Introduction: Breast diseases in paediatric and adolescence are unusual. Fine Needle Aspiration Cytology (FNAC) has an important role in triaging breast masses, more so in younger population, wherein preoperative accurate diagnosis has significant impact on selecting and planning treatment. Role of FNAC in breast lesions amongst children and adolescents has not been explored much.
Aim: To study the role of FNAC in diagnosis of breast lesions in children and adolescents.
Materials and Methods: A cross-sectional study was conducted between June 2017 to May 2019 at Adichunchanagiri Institute of Medical Sciences, Mandya, Karnataka, India. All the patients presenting with breast lesion aged below 21 years, referred to FNAC clinic during this period were included in the study. The diagnoses were categorised as inflammatory, benign, atypia, suspicious and malignant. Cytohistopathology concordance was attempted wherever possible. Analysis was done using Statistical Package for the Social Sciences (SPSS) software version 17.0.
Results: Out of total 45 cases, 37 (82.22%) were females and 8 (17.78%) were males. Breast lesions in paediatric and adolescents accounted for 15.20% (45/296) of total breast FNAC performed during the study period. The morphologic spectrum seen most commonly was fibroadenoma (FA) 62.22% (2-8/45), benign breast disease 8.88% (4/45), mastitis 4.44% (2/45). Morphologic variations observed in FA were epithelial hyperplasia 32.14% (9/28), cystic change 28.57% (8/28), hyper cellular stoma 21.42% (6/28), multinucleate giant cells 32.14% (9/28), apocrine change 14.28% (4/28), adenosis 10.71% (3/28), columnar cell change 10.71% (3/28), squamous metaplasia 3.57% (1/28) and atypia 3.57%(1/28). Histopathologic correlation was obtained in 31 cases (68.88%). Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of FNAC was found to be 50, 100%, 100%, 96.6%, 96.77%, respectively.
Conclusion: Majority of the breast lesions in paediatric and adolescents are benign in nature with FA being the most common. FNAC had high specificity and diagnostic accuracy, thereby establishing its role in selecting appropriate treatment for this age group of patients.
