Abstract
Male breast cancer is rare, accounting for less than 1% of all breast cancer cases. Intracystic papillary carcinoma (IPC) of the breast is an extremely rare malignant tumor, particularly in men. It is a subtype of non-invasive encapsulated carcinoma that often presents with a benign appearance on imaging. We report the case of a 42-year-old man who presented with a right breast mass. Ultrasound revealed a solid-cystic lesion classified as BI-RADS 4. The biopsy confirmed the diagnosis of IPC. This case highlights the role of breast imaging in the detection and diagnostic guidance of rare papillary lesions in men.
