Breast cancer in men accounts for only 1% of all breast cancers. Intracystic papillary carcinoma (IPC) of the male breast is a rare subtype of breast cancer, representing <0.5% of all breast cancers and often challenging to diagnose due to its indolent nature and cystic presentation.

We report a case of a 60-year-old male farmer who presented with a 5-year history of a right retroareolar lump, rapidly increasing in size over the last 5 months and associated with dull aching pain. Clinical and imaging evaluation revealed a retroareolar cystic lesion with a solid component. Core biopsy confirmed papillary carcinoma. The patient underwent right mastectomy with axillary sampling. Histopathology revealed intracystic papillary carcinoma with foci of invasive ductal carcinoma. Hormone receptor status was ER/PR positive, and the patient was started on tamoxifen. Follow-up was uneventful.

Male IPC is a rare but treatable breast neoplasm. Timely evaluation using a combination of imaging, histopathology, and surgical excision is crucial. Endocrine therapy is beneficial in receptor-positive patients.
