# A Case of Breast Papillary Carcinoma in an Elderly Black Male Patient With Pathology, Ultrasound, and Mammogram Imaging Findings

## TL;DR

This paper presents a rare case of breast papillary carcinoma in an elderly Black male, including imaging and pathology results.

## Contribution

Adds a new case report of male breast papillary carcinoma with detailed imaging and pathological findings.

## Key findings

- Ultrasound showed a complex, cystic mass.
- Mammogram revealed a well-circumscribed, high-density lesion.
- Immunostaining showed absence of myoepithelial cells in fibrovascular cores.

## Abstract

The patient was an 84-year-old man who presented with a palpable, left breast mass. Following ultrasound, mammography, and ultrasound-guided core needle biopsy, the lesion was diagnosed as papillary carcinoma. Findings included a complex, cystic mass on ultrasound; a well-circumscribed, high-density lesion on mammogram; and a lack of highlighting of myoepithelial cells within fibrovascular cores on immunostaining. With this case report, we aim to add to the literature an additional example of breast papillary carcinoma in a male patient and its corresponding imaging and pathologic findings.
