Fine needle aspiration cytology (FNAC) is now an established procedure for the evaluation of breast masses in women. But there are only occasional reports of aspiration cytology of rare malignant neoplasms of male breast. During the past 8 years the authors detected 12 malignant neoplasms of male breast by FNAC out of total 167 cases of aspirates of male breast lesions. There were eight infiltrating ductal carcinomas, two leiomyosarcomas and two metestatic carcinomas. The cytologic features with short review of literature of male breast carcinomas are presented. Due to high diagnostic accuracy, FNAC should be routinely practiced as a quick and safe diagnostic procedure in all outpatients department.
