A case of desmoplastic fibroblastoma of the chest wall

Abstract

A 54-year-old woman complaining of a subscapular tumor was referred to our hospital. The tumor was located in the right subscapular area, and it was 3 cm in diameter, hard, and unmovable from the chest wall. CT revealed an ill-defined soft-tissue tumor. The tumor was iso-intense on T1-weighted MR imaging, with a low intensity inside and high intensity outside. We could not obtain a preoperative histological diagnosis, but suspected the tumor to be an elastofibroma because of its location. After resection of the tumor, it was diagnosed as a desmoplastic fibroblastoma, one of the rare histological types of soft tissue tumors.
