A Case Report of Juvenile Hypertrophy of the Breast in a 15-Year-Old Girl: Presented with Asymmetric Breast Enlargement and a Focal Mass-like Lesion

ABSTRACT

Juvenile hypertrophy of the breast is a rare condition, leading to hyperplastic breast anomalies in adolescents. Here, we report a case involving a 15-year-old girl, presented with asymmetric enlargement of the left breast. Pronounced parenchymal thickening was found on initial ultrasonography (US). MRI and second-look US revealed a focal mass-like lesion on the left mid-lateral breast, confirmed as juvenile hypertrophy of the breast on pathology.
