[Echographic aspects of gynecomastia]

Area of Science:

• Medical Imaging
• Endocrinology
• Pathology

Background:

• Gynecomastia is characterized by male breast tissue enlargement due to non-neoplastic proliferation.
• Two main types are recognized: 'florid' (ductal proliferation) and 'quiescent' (stromal proliferation).
• Pseudo-gynecomastia involves non-glandular volume increase, distinct from true gynecomastia.

Purpose of the Study:

• To evaluate the diagnostic capabilities of sonography in male breast conditions.
• To differentiate between gynecomastia and pseudo-gynecomastia using ultrasound.
• To correlate sonographic findings with anatomopathologic patterns for therapeutic guidance.

Main Methods:

• Sonographic examination of the male breast.
• Identification of normal male breast structures.
• Classification of gynecomastia based on sonographic echo-patterns.

Main Results:

• Sonography accurately identifies normal male breast anatomy.
• Ultrasound effectively diagnoses gynecomastia and distinguishes it from pseudo-gynecomastia.
• Three distinct sonographic echo-patterns correlate with anatomopathologic features of gynecomastia.

Conclusions:

• Sonography is a valuable tool for diagnosing male breast conditions.
• Ultrasound-based classification of gynecomastia aids in understanding underlying pathology.
• Sonographic findings can inform and direct therapeutic strategies for gynecomastia.
