# Incidental Bilateral Ductal Carcinoma In Situ (DCIS) in Excisional Surgery for Gynecomastia

## TL;DR

A 47-year-old man had early-stage breast cancer found during surgery for gynecomastia, highlighting the need for thorough testing in male breast cases.

## Contribution

Highlights the importance of pathological evaluation in male breast surgeries, even for non-cancerous conditions.

## Key findings

- Bilateral ductal carcinoma in situ was incidentally found during gynecomastia surgery.
- The case underscores the need for routine pathology testing in male breast tissue.
- Early detection was possible due to tissue examination following weight loss.

## Abstract

Male breast cancer is a rare disease, and it is important to have a high index of suspicion in patients presenting with breast symptoms, such as a breast mass or nipple discharge. Most male patients who are diagnosed with breast cancer present with breast complaints and/or a strong family history of cancer. Here, we will present a 47-year-old male patient who was diagnosed with bilateral ductal carcinoma in situ during a routine gynecomastia surgery after massive weight loss. This case demonstrates the importance of sending breast tissue specimens for pathology, especially in a male patient.
