Giant breast hamartoma

Abstract

A 14-year-old girl presented with a painless and progressively growing swelling involving the left breast of one year's duration. Physical examination revealed a non-tender well circumscribed lobulated mobile mass in the left breast. Magnetic Resonance Imaging studies revealed a well encapsulated mass lesion in the left breast predominantly containing fat in the upper quadrants (Fig. 1A). T1 weighted images showed randomly oriented hypointense areas within the lesion which turned hyperintense on T2 weighted images with no evidence of increased vascularity. This suggested a benign breast lesion, possibly a hamartoma. The patient underwent excision of the lump through a circumareolar approach followed by mastopexy to correct the ptosis of the breast. The lesion measured 13 × 9 cm (Fig. 1B). Histopathology showed lobular ducts surrounded by loose stroma and hyalinized connective tissue along with adipose tissue consistent with fi broadenolipoma (Fig. 2). She is recurrence free after one year follow-up.Hamartomas of the breast are uncommon benign breast tumours and constitute 0.7% of all benign tumours of the female breast [1]. Giant breast hamartomas are rarely encountered [2]. Hamartoma of the breast are usually encountered during the fourth and fi fth decades. They constitute the IMAGES IN SURGERY

“…Breast hamartoma also is known as fibroadenolipoma is a rare benign condition of indeterminate cause and pathogenesis [1]. Due to its rarity and benign nature, it is usually undiagnosed or has delayed diagnosis [2].…”
