# Adenoma of the Nipple: A Case Report

## TL;DR

This case report describes a rare benign breast condition called nipple adenoma in a 69-year-old woman, emphasizing the importance of histology for diagnosis and surgical management.

## Contribution

The paper presents a rare case of bilateral nipple adenomas and discusses management strategies including complete resection and partial excision.

## Key findings

- Nipple adenomas can present with unilateral bloody discharge and a palpable mass, mimicking breast malignancies.
- Histologic and immunohistochemistry evaluation is essential for accurate diagnosis due to limited imaging specificity.
- Complete resection with clear margins is the primary treatment to prevent recurrence, though partial excision may be viable in selected cases.

## Abstract

Nipple adenomas are rare, benign breast lesions that present similarly to breast malignancies, often manifesting with unilateral bloody discharge, a palpable mass, and/or nipple distortion. Imaging techniques have limited specificity in distinguishing nipple adenomas from malignancy; therefore, clinicians must rely on histologic and immunohistochemistry evaluation. Here, we highlight the case of a 69-year-old woman with bilateral nipple adenomas presenting as an enlarging nipple mass with chronic nipple discharge. Complete lesion resection with clear margins stands as the primary route of management and complete avoidance of re-occurrence. However, partial excision with nipple preservation has been reported to be successful in selected cases.
