Developmental disorders and malformations of the breast

Area of Science:

• Reproductive medicine
• Developmental biology
• Pathology

Background:

• Breast development abnormalities are uncommon, encompassing genetic, syndromic, acquired, and sporadic conditions.
• These abnormalities can affect the nipple-areolar complex and glandular tissue, leading to under- or overdevelopment.
• Presentation and severity vary based on the underlying biological cause.

Purpose of the Study:

• To review the spectrum of breast development disorders.
• To discuss the etiologies, clinical presentations, and histopathologic features of these conditions.

Main Methods:

• Literature review of breast development disorders.
• Synthesis of information on etiologies, clinical presentations, and histopathology.

Main Results:

• Abnormalities can be global (unilateral or bilateral) or focal, including tumor-like lesions like hamartomas, pseudoangiomatous stromal hyperplasia, and gynecomastia.
• Syndromic and endocrine abnormalities are often associated with widespread breast development issues.
• Histopathologic examination is crucial for diagnosis.

Conclusions:

• Breast development disorders present a diverse range of conditions with varied etiologies and manifestations.
• Understanding the clinical and histopathologic features is essential for accurate diagnosis and management.
