Pleural Mesothelioma Diagnosed on Inguinal Lymph Node Biopsy: A Rare Entity ED06-ED07
Dr. Arvind Kumar Gupta,
Department of Pathology, AIIMS Rishikesh, Uttarakhand, India.
Mesothelioma is a locally aggressive tumour arising from mesothelial lining of serous cavities, commonest site being the pleura. Distant metastasis to extra thoracic lymph node is rare. We herewith report a case of pleural mesothelioma with extensive peritoneal involvement which was diagnosed after inguinal node biopsy. This case highlights the aggressive nature of mesothelioma along with unusual site of metastasis. Though rare, a differential diagnosis of malignant mesothelioma should be kept while dealing with patients presenting with ascites and inguinal lymphadenopathy. A high index of suspicion along with immunohistochemical confirmation can prevent disease progression and prolong patient survival.
