An Adolescent Girl with Giant Fibroadenoma - A Case Report.

Though fibroadenoma is the most common benign tumor of the breast and is more common under the age of 30, giant fibroadenoma is rare representing less than 4% of all fibroadenomas. A 12 years old girl presented with rapidly enlarging well-circumscribed firm, non-tender mass in right breast for 2 months which was painless and with no history of trauma, nipple discharge, fever, anorexia, weight loss or axillary lymphadenopathy. There was no family history of neoplasms. Clinically, the lump was about 12 × 12 cm and not fixed to skin or underlying structures with the absence of nipple retraction or discharge. There was no axillary lymphadenopathy. Fine needle aspiration cytology showed a benign proliferative breast disease. Total excision of mass was done preserving nipple and areola having weight of 535 gm with histopathological features suggestive of giant fibroadenoma. Giant fibroadenoma is a benign breast disease that may mimic rare malignant lesion. So, breast and nipple conserving surgery should always be performed irrespective of size of tumor as in this case.
