Abstract
Juvenile fibroadenoma comprises about 4% of the total fibroadenomas. The incidence of giant juvenile fibroadenomas is merely 0.5% of all the fibroadenomas. Bilateral giant juvenile fibroadenomas are extremely rare. We are presenting a case of giant juvenile fibroadenomas in an 11-year-old pre-pubertal girl. The diagnosis was made on fine-needle aspiration cytology which was confirmed on histopathology. As these tumors are mostly benign, breast-conserving surgery is done so that patient can lead a normal life without psychological trauma. ----------------------------------- Cite this article as : Goyal S, Garg G, Narang S.

Highlights
Fibroadenoma of the breast is a benign tumor affecting females usually before the age of 30.[1]
If fibroadenoma occupies a major fraction of the breast and weighs more than 500 gram, it is named as "giant fibroadenoma breast"
In 1829, Sir Astley Coop described fibroadenomata as a tumor belonging to a group called "chronic mammary tumors." Subsequently, Brodie classified fibroadenoma as "sero-cystic tumors of the female breast"
Summary
Fibroadenoma of the breast is a benign tumor affecting females usually before the age of 30 (commonly between 10-18 years).[1]. In 1934, Oliver described breast mass as benign growth and named it as fibroadenomata.[2] Fibroadenomas and abscess are common in breasts of children. An 11-year-old pre-menarche girl presented with rapidly enlarging right breast lump for three months. There was no history of trauma, nipple discharge, fever, anorexia, or weight loss. On local examination there was a slightly tender, huge, well-circumscribed mass in the right breast which was firm in consistency. The right breast lump measured 16 × 13 cm. Ultrasonography of breast showed heterogeneous parenchymal pattern suggestive of fibroadenoma. Fine-needle aspiration cytology (FNAC) of breast lumps showed cellular smears comprising of many branching monolayer sheets along with myoepithelial cells (Figure 1). Based on the cytological findings, diagnosis of benign proliferative lesion without atypia suggestive of fibroadenomas was made.
