Background: Juvenile breast hypertrophy is a rare benign condition leading to rapid and massive enlargement of one or both breasts in young girls during peri-pubertal period. Patients encounter physical and psycho-social problems. Therefore, the condition warrants early appropriate management. Breast imaging studies (ultrasound and magnetic resonance imaging) are particularly important in order to exclude tumors and occult pathologies. First line treatment modality is reduction mammoplasty that significantly improves quality of life with lesser chances of recurrence. Case Presentation: We report two post-menarchal girls with juvenile breast hypertrophy who presented as different clinical cases facing psychological and social embarrassment. Breast ultrasound showed right breast mass in both patients that were biopsied. The lesions turned out to be fibroadenomas on histopathological correlation. Patients were then referred to plastic surgery and endocrinology department. Conclusion: Juvenile breast hypertrophy is definitely a disturbing cosmetic problem. Early investigations and appropriate management will surely leave a positive impact on the quality of life.
