A Case of Juvenile Giant Fibroadenoma of Breast: A Diagnostic Dilemma

Abstract

Fibroadenomas are the most common type of breast tumours diagnosed in young women. Fibroadenomas found in children and adolescents are termed as juvenile fibroadenomas of which giant fibroadenomas are rare account for 0.5%-2% of all fibroadenomas, that cause asymmetry of the breasts and are characterised by rapidly growing mass of more than 5 cm in greatest dimension, and/ or weight more than 500 gm, or replaces at least 80% of the breast. Both phyllodes tumour and giant fibroadenoma have similar clinical presentations. The current case is of 15-year-old female with a rapidly growing mass in the left breast with in a span of six month duration measuring 15×10 cm and was associated with dilated veins over it. The clinical diagnosis was suggestive of phyllodes tumour. Cytopathological and histopathological reports showed the evidence of juvenile giant fibroadenoma. Hence, the purpose of this report is to differentiate phyllodes tumour from juvenile giant fibroadenoma preoperatively to obtain the best cosmetic outcome for a developing breast lesion.
