ABSTRACT
Intracystic papilloma (ICP) of the breast in males is extremely rare. We reported the 13th male patients presented in literature, complaning about ICP in his right breast. The patient had a history of a painful enlarging mass for about 6 months. Ultrasonography revealed a cyst with an intracystic component. Because the radiologic and clinical features of benign ICP are similar as intracystic carcinoma, complex cystic masses with solid components require biopsy. Sonographically guided core needle biopsy can be performed for differential diagnosis of benign ICP and intracystic carcinoma. Otherwise surgical resection is recommended as a diagnostic and therapeutic method for ICP. Excisional biopsy was performed under local anesthesia for our patient. Pathological examination revealed the intracystic component to be benign IP.
