We presents a case of juvenile fibroadenoma of the breast in a 14 year old girl, presented with rapidly growing mass in the right breast of four months duration. On local examination a solitary, firm, mobile, unilateral, non-tender mass was felt in the upper and lower outer quadrant of the right breast, measuring 6.5 x 4.1 x 3.5cm. The overlying skin was normal. There was no axillary lymphadenopathy. The sonomammography of the right breast showed a single, oval, hypoechoic, well circumscribed mass lesion with cleft like spaces features suggestive of complex fibroadenoma BIRADS IV a. On fine niddle aspiration cytology showed sheets of hyperplastic benign ductal epithelial cells with myoepithelial cells and a background of benign bipolar nuclei and blood, without inflammatory cells. It was suggestive of fibroadenoma. She underwent right lumpectomy with breast conservation. We received right breast lumpectomy specimen. On gross showed a well-circumscribed, grey white, firm mass m 6.3 x 4.1 x 3.2 cm. On histologic features reported as juvenile fibroadenoma right breast. The postoperative period was uneventful and she recovered well and advise regular follow up. Conclusion: Juvenile fibroadenomas are rare benign breast tumors that should be distinguished from other masses of breast. Herewith we are presenting case of Juvenile fibroadenoma for its clinical, radio imaging, pathological features and management.

They can result in an esthetic problem due to breast asymmetry or hypertrophy. 3 In the majority of pediatricbreast lesions they are of benign etiology, therefore the management approach should be proper. 2.
