Spectrum of disease in the male breast

Abstract

Objective: The purpose of this article is to review the anatomy of the male breast and to describe the imaging findings of a variety of diseases that affect the male breast to better understand and recognize the imaging findings and underlying pathophysiology of diseases and conditions affecting this emerging subset of patients.

Conclusion: Understanding the anatomy of the male breast is central to developing a differential diagnosis and delivering optimal care in male patients presenting with breast complaints. Diseases in the male breast can affect the skin and subcutaneous tissues, stroma and glandular elements, and neurovascular and lymphatic structures. Although the most commonly encountered disease entity is gynecomastia, men can develop many other benign and neoplastic diseases, including primary breast cancer. By incorporating clinical presentation with imaging findings on mammography and ultrasound, the breast imager can more effectively establish the correct diagnosis in males.
