Case of a Calcified Epithelioma with a Suspected Solitary Fibrous Tumor

The patient was a 16-year-old girl. She noticed gradual increase in the size of skin mass on right posterior neck and observed redness 1 month prior to visiting our department. 4 cm size, dome-shaped, side neck. Ultrasound images showed well-defined oval heterogeneous isoechoic mass. interior rich blood flow with some coarse calcifications. Magnetic resonance imaging uniform hypointensity T1-weighted variable hyperintensity superficial layers T2-weighted images. On basis these findings, solitary fibrous tumor suspected. resected at proximal margin under general anesthesia. erythematous, overlying partially adherent fascia. diagnosed as calcified epithelioma.Solitary tumors are histologically fibroblastic mesenchymal neoplasms, which include hemangiopericytomas. Generally, arise within thoracic cavity, but few cases have been reported subcutaneous soft tissue. We encountered epithelioma that we suspected be imaging. Because similar rare, report this case along literature review.
