CT scan showed multiple extensive peritoneal lesions, and peritoneal fluid cytology analysis confirmed the presence of neoplastic cells. CT-guided biopsy was performed and a histological diagnosis of epithelioid MST (Figures 1, 2) (phenotype: CK-AE1AE3+, CK5/6+, Calretinin+, Vimentin+, WT1+, BerEp4-) was established.
