Bladder perivascular epithelioid cell tumors
Introduction: Perivascular epithelioid cell tumors (PEComas) of the bladder are infrequent localisation of this mesenchymal cancer with uncertain malignant behavior.
Case report: We report the case of a 74 years old women who was diagnosed a malignant PEComa of the bladder. She necessited radical cystectomy with orthotopic ileocaecal pouch reconstruction. Histology and immunohistochemistry confirmed the diagnosis of a malignant PEComa of the bladder. We evaluate the literature cases to adjust the prognosis criteria.
Conclusion: Evolution and prognosis evaluation remain hard and could necessitate a radical surgery. Prognosis criteria for the bladder PEComas have to be clarified.
