Man With Gynecomastia, Gross Anatomy

Description

Presented as an anterior full-body 3D male figure in neutral anatomical position, the chest contour highlights enlargement centered at the nipple-areolar complex consistent with gynecomastia. Subareolar glandular tissue occupies the superficial fascia overlying pectoralis major, with the areola and nipple projecting anteriorly while the pectoral mass remains deep and posterior to the breast mound. Medially, the sternum and parasternal region frame the medial borders of the pectoralis major; laterally, the anterior axillary fold defines the transition toward the axilla and upper arm. Gynecomastia is a patterned process, usually a firm, rubbery retroareolar disc rather than diffuse adiposity, so this view supports the key teaching point of distinguishing true gland development from pseudogynecomastia in obesity. The relationship to pectoralis major matters in operative planning, because subcutaneous mastectomy and contouring liposuction work in the plane superficial to the pectoral fascia while preserving the nipple-areolar complex and its perforator supply from the internal thoracic and lateral thoracic systems. A common clinical context is pubertal or medication-associated gynecomastia (for example spironolactone, antiandrogens, or anabolic steroids), where asymmetric enlargement, tenderness, and psychosocial impact often drive evaluation and treatment. Ideal for endocrine and reproductive blocks, physical diagnosis teaching on male breast examination, and surgical education on chest wall landmarks and incision placement (periareolar vs inframammary) for gynecomastia correction. It also fits patient-facing counseling materials that need a clear, non-photographic representation of male breast gland enlargement against otherwise typical adult male musculature.
