Huge Cavernous Hemangioma Arising in a Male Breast

Abstract

We report a rare case of a huge cavernous hemangioma arising in a male breast.
A 60-year-old man first noticed 1 × 2 cm elastic hard nodule just below his right nipple ten years previously. It enlarged 5 × 5 cm over six years. When he came to our clinic, it was size of child head (510 mm in circumference), was an elastic hard with a rather smooth surface, and firmly fixed to the chest wall. Magnetic resonance imaging (MRI) and multidetectocomputed tomography (MDCT) showed a large mass infiltrating into the chest wall. Fine needle aspiration cytology (FNA) and core needle biopsy (CNB) failed to obtain proper material except for old bloody fluid or necrotic connective tissue, precluding a correct diagnosis preoperatively. Mastectomy with partial resection of the chest wall was subsequently performed. Histologically, it was found to be a cavernous hemangioma without cellular atypia. In such a case, complete excision is recommended to exclude the possibility of an underlying malignant lesion.
