Unilateral gigantomastia related to juvenile fibroadenoma with idiopathic thoracic scoliosis.

A 15-year-old girl was referred to our Department by the orthopedic surgeons, showing a massive unilateral gigantomastia of her right breast and a progressive idiopathic thoracic scoliosis. Ventral positioning of the patient for the planned scoliosis correction was impossible without prior treatment of the hypertrophic breast. In the first operation the fibroadenoma with a total weight of 3020 g was resected and histological examination revealed diagnosis of a juvenile giant fibroadenoma, which is a rare tumor of the stromal breast tissue. Tumor resection was followed by anterior thoracic release and posterior scoliosis correction.
