"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Rhabdomyosarcoma (RMS) is a rare soft tissue tumour, accounting for 3% of all childhood cancers. RMS can arise virtually anywhere in the body, as it originates in embryonal mesenchyme. Embryonal Rhabdomyosarcoma (ERMS) and Alveolar Rhabdomyosarcoma (ARMS) are the most prevalent subtypes of RMS but arise through diverse biological mechanisms. RMS generally presents as an expanding mass that tends to be very painful and causes symptoms related to the compression of structures present nearby. Metastases of such tumours are common and can occur in bone, lungs and other organs leading to pain, difficulty with respiration, pleural effusion, anaemia, thrombocytopenia, and neutropenia. In the present report, two unusual presentations of ERMS have been reported. First case is of a 28-year-old adult male who presented in surgical Outpatient Department (OPD) with recurrent episodes of painful acute urinary retention since one year. Another case was of a six-year-old girl presenting with aural fullness and serosanginous discharge from right ear, ear pain and decreased hearing since two years. Since five year survival rate of such tumour is less than 30%, therefore, an awareness of the typical signs and symptoms, radiological features, histomorphological features in a case of paediatric and adult ERMS can help a pathologist to consider this tumour in the differential diagnoses, even at unusual sites.

Case Report

Case 1

A 28-year-old male presented in the Department of Surgery with on and off episodes of painful micturition and inability to empty bladder completely since one year. There was no significant past medical or family history. Digital rectal examination revealed a smooth palpable cystic mass underlying the anterior rectal wall. Rectal mucosa was free of lesion. Computed Tomography (CT) urography revealed a large heterogeneously enhancing lesion measuring 5.5×5 cm in the prostate gland on left side causing displacement of urethra to right side (Table/Fig 1)a. Magnetic Resonance Imaging (MRI) prostate with spectroscopy revealed a large solid cystic mass in left side of prostate showing heterogenous enhancement, restricted diffusion, high choline and no periprostatic spread or significant lymph nodes (Table/Fig 1)b. Fine Needle Aspiration Cytology (FNAC) was performed at a peripheral lab and reported as a spindle cell neoplasm displaying a cellular smear composed of sheets and nests of spindle cells and few small round blue cells with scant cytoplasm along with frequent mitotic figures.

The patient open radical prostatectomy with vesicourethral anastamosis with bilateral pelvic lymph node dissection. Prostatectomy specimen measuring 5×4.5×4.5 cm was received. Cut surface showed a tumour measuring 4.5×4 cm involving almost the entire prostate. Bilateral seminal vesicles and vas deferens were free of tumour. On histopathology, tumour was arranged in interlacing fascicles interspersed by focal areas of necrosis. Tumour cells displayed spindle shaped nuclei, vesicular chromatin, inconspicuous nucleoli and scant amount of eosinophilic cytoplasm. Brisk mitotic activity was seen. Normal prostatic acini were noted in the peripheral area (Table/Fig 1)c,d, (Table/Fig 2)a. Based on the histopathology, differential diagnosis of leiomyosarcoma was kept with a low suspicion of prostatic adenocarcinoma undergoing sarcomatous transformation. Hence, additional sections were taken to look for areas of carcinoma. Extensive sampling yielded no focus of adenocarcinoma. On Immunohistochemistry (IHC), tumour cells displayed diffuse positivity for vimentin, focal positivity for desmin and negativity for Smooth Muscle Actin (SMA). Owing to negative staining of SMA, possibility of leiomyosarcoma was excluded.

A closer inspection showed a small focus showing round to oval cells with abundant amount of eosinophilic cytoplasm along with occasional strap shaped eosinophilic rhabdomyoblasts. An extended panel including myogenin was applied which showed diffuse nuclear positivity (Table/Fig 2)b. Thus, owing to the predominance of spindle cells, focal areas of rhabdomyoblasts and IHC positivity for myogenin, the present case was reported as spindle cell variant of ERMS. Patient underwent radiotherapy, but was, lost to follow-up.

Case 2

A six-year-old girl presented with blood tinged discharge from right ear, ear pain and decreased hearing for 15 days. She had aural fullness for past two years. On examination, a mastoid swelling measuring 4×4 cm was seen which was non tender, mobile with normal appearing overlying skin. Otological examination revealed an aural polyp measuring 2×2×1 cm protruding from the external auditory meatus. The CT scan showed an ill-defined heterogenous mass of size 6×4 cm with hypodense centre which was eroding the mastoid bone (Table/Fig 3)a.

Fine Needle Aspiration Cytology (FNAC) was performed from the postauricular mastoid swelling which was highly cellular and revealed diffusely scattered medium sized round, oval to spindle shaped cells with hyperchromatic nuclei and scant amount of cytoplasm. Occasional rhabdomyoblasts were also noted (Table/Fig 3)b,c. Based on cytomorphology and clinical profile, a provisional diagnosis of small round blue cell tumour, most likely ERMS was made. The aural polyp was excised and mastoidectomy was done and excised tissue was sent for histopathological examination. Both the tissues showed similar histomorphology. The tumour was lined by startified squamous epithelium with a cellular cambium layer underneath it. Diffusely scattered tumour was noted in a background of loose, myxoid stroma. Tumour cells were round, oval to spindle in shape with hyperchromatic nuclei, inconspicuous nucleoli and scant amount of cytoplasm. Occasional strap cells were also noted (Table/Fig 3)d, (Table/Fig 4)a. IHC showed diffuse cytoplasmic positivity for vimentin, nuclear positivity for myogenin (Table/Fig 4)b. The diagnosis of ERMS was confirmed. Patient was lost to follow-up.

Discussion

The RMS can develop in almost any part of the body, most common site being genitourinary organs accounting for 29% of the cases. The orbit is the most usual location for paediatric RMS, but it can occur in the oral cavity, pharynx, face, and neck in descending order of incidences (1). Involvement of the ear and temporal bone is uncommon (2). RMS has a broad range of reported age range between 17-68 years and only few cases are reported in adults (2),(3). Embryonal, botryoid, alveolar, pleomorphic, spindle cell and anaplastic variants are the pathologic subtypes of RMS and ERMS and comprises of about 60-70% of RMS (4). Though ERMS is generally regarded as a neoplasm occurring primarily during childhood, but there are few reports in the literature that occurred in adults (5). Prostate ERMS is a common tumour in infants and children, with a median occurrence age of 5 years (6). A 15-20% of all RMSs arise from the genitourinary tract. It has the proclivity to involve the hollow organs like bladder, prostate, paratesticular region, uterus and vagina and it is the 3rd most common extracranial solid tumour of childhood after nephroblastoma and neuroblastoma (7). The common variants of sarcomas affecting the prostate include leiomyosarcoma, RMS, malignant fibrous histiocytoma and unclassified sarcoma. Among all these, RMS is the most common histological subtype that accounts for approximately 40% of prostate sarcomas in children. Leimyosarcoma accounts for nearly 25% cases and mostly occurs in the elderly (8). When an adult male presents with lower urinary tract obstruction and markedly enlarged prostate with normal Prostate-Specific Antigen (PSA) levels, prostate sarcoma is often suspected (9).

Spindle cell lesions of prostate poses a great diagnostic challenge as it encompass a broad range of benign and malignant tumours originating from the prostate epithelium or stroma, such as sclerosing adenosis, sarcomatoid carcinoma, Stromal Tumours of Uncertain Malignant Potential (STUMP), stromal sarcoma, Solitary Fibrous Tumour (SFT), leiomyosarcoma, Inflammatory Myofibroblastic Tumour (IMT), Gastrointestinal Stromal Tumour (GIST), fibrosarcoma and Malignant Peripheral Nerve Sheath Tumour (MPNST) (10). Identification of benign or malignant nature of tumour cells along with admixture of benign or malignant glands and the presence of heterologous elements are the few useful features that aids in distinguishing these lesions from one another. Admixture of prostate glands with the spindle cell lesion poses a more specific differential diagnosis as in the present case like some patterns of STUMP, stromal sarcomas (malignant phyllodes pattern), sarcomatoid carcinoma and sclerosing adenosis. In sclerosing adenosis, STUMPs and stromal sarcoma, the glandular component is typically benign, whereas sarcomatoid carcinoma shows admixed adenocarcinoma component. Rest of the lesions like IMTs, leiomyosarcomas, GISTs and SFTs generally grow in an expansile pattern without any admixed glandular element. In such pure spindle cell lesions, cytological features and growth pattern are two important features in diagnosis of these entities (9). The recognition of rhabdomyoblast is the key to the diagnosis of RMS. However, in more primitive tumours, IHC such as myogenin, myo-D1 and desmin can help to confirm diagnosis of RMS (10).

Clinical features of ERMS include rapidly progressing obstructive urinary symptoms, enlargement of prostate on digital rectal examination, infrequent suprapubic mass, involvement of nearby lymph nodes, difficulty in breathing due to lung metastasis, osteoclastic bone metastasis and normal serological markers like PSA levels and prostatic acid phosphates (11),(12). Botryoide type of ERMS is the usual presentation of urogenital RMS in children and they respond well to radiation and chemotherapy (13). In contrast, adults usually present with non embryonal subtypes which tend to be widely disseminated. The results are poor and despite good initial responses to chemotherapy, they eventually die of their disease (14). The lack of awareness of this entity in adults, delay in diagnosis and more aggressive behaviour of this malignancy are some of the reasons (3). Localised presentation and favourable prognosis of index case was due to the histological subtype. Cases with spindle cell morphology of ERMS are extremely rare and till date, only four similar cases have been reported in literature, index case is the fifth such case. Schildhaus HU et al., published a case of 25-year-old male with problem of micturition which was reported as spindle cell variant of ERMS (15).

Rhabdomyosarcoma (RMS) in the head and neck can occur in the orbit, pterygopalatine fossa, parapharyngeal space, nasopharynx but very rarely in the middle ear and mastoid. RMS of mastoid is a deadly neoplasm that occurs almost exclusively in paediatric age group. Hence, the misdiagnosis as aural polyp is generally made. Therefore, such tumour presents as advanced disease at the time of diagnosis (16). Clinical features of such tumours include purulent, blood tinged ear discharge, hearing impairment, earache, aural polyp. Advanced cases may present with neurologic symptoms. As these features are non specific, they can lead to a delayed diagnosis. Therefore, most of these patients are initially managed on antibiotics and only when this treatment fails, other diagnosis is suspected (17).

In 1966, Potter reported a 3-year-old male with bilateral otitis media and polypoidal external auditory canal mass that turned out to be RMS (18). Metastases of such tumours commonly spread to the lungs, liver, bones and extremities, and are present in approximately 30% of cases (19). The main treatment is often chemo-radiotherapy. Parameningeal tumours, especially of the middle ear and mastoid have a poor prognosis because of the involvement of the brain (20).

Conclusion

The possibility of prostatic RMS should be kept in mind when a young male presents with prostate mass, lower urinary tract symptom and normal PSA. Likewise the diagnosis of RMS should be sought for in a child presenting with mastoiditis and not responding to the routine therapy. A high index of suspicion is needed to avert a grave prognosis. Timely detection and early diagnosis are the key to successful management of these sarcomas at rare sites.
