[Mammographic findings of gynecomastia].

Objective: To investigate the features of gynecomastia displayed by mammography.

Methods: Twelve patients with gynecomastia were examined with a high-performance GITTO-TECH mammograph (IMS Company, Italy), and the results were compared with those obtained from pathological examination.

Results: The 12 cases were pathologically confirmed as gynecomastia, 10 of which were also identified by mammography while 2 misdiagnosed as male breast cancer.

Conclusion: Diagnosis of gynecomastia can be established when typical features are presented in mammography, and fine needle aspiration biopsy can be performed when possible for discrimination from male breast cancer.
