Abstract: Intracystic papillary carcinoma (IPC) is a rare tumor with good prognosis that occurs in only 5% to 7.5% of male breast cancer. We report a case of a 46-year-old man who presented a brown nipple discharge a few months ago. He had a bilateral IPC and an invasive ductal carcinoma on the right breast. A double mastectomy was then performed with a bilateral sentinel lymph node biopsy, and he received chemotherapy, radiotherapy, and hormonotherapy. Two years after the diagnosis, the patient recovered and was free of recurrence. Considering the scarcity of this tumor type, we conducted a systematic literature review on the PubMed of all the cases of IPC in men. The clinical presentation, imaging, and treatment of the 43 case reports from the 41 articles selected were described. Furthermore, no clear guidelines for IPC management are available. Conservative surgery should also be preferred, and a sentinel lymph node biopsy should be performed systematically. Moreover, radiotherapy should be proposed in the case of conservative surgery, and hormone therapy could be proposed in the case of invasive IPC or IPC associated with a ductal carcinoma in situ.
