Case report: Intraductal papilloma in a male patient

Abstract

Introduction: In this case report, we discussed a rare case of an intraductal papilloma (IP) in a male patient. Intraductal papilloma of the breast is a benign tumor characterized by fibrovascular cores lined by an outer epithelial layer and inner myoepithelial layer.

Case Presentation: Our patient was a 36-year-old male who presented with a 6-month history of a bloody discharge from the right nipple. Mammography revealed right retroareolar, fibroglandular parenchyma with no associated discrete masses or suspicious microcalcifications. Ultrasound imaging revealed a lesion within the dilated ducts in the right breast. This was concordant with the biopsy result, which confirmed an IP with no evidence of malignancy. Although IPs are benign tumors, they can lead to atypical hyperplasia or ductal carcinoma in situ. Therefore, this patient was managed with total ductal excision, and the final histopathological examination confirmed the preoperative diagnosis.

Conclusion: IP is a rare condition in male patients and should warrant proper investigations. Surgical excision is the current mainstay of such condition.
