Exophytic Myxoid Liposarcoma of the Bladder Developed Around A Cystostomy: A Rare Form of Revelation

Introduction: Myxoid liposarcoma is a sarcoma of the supporting tissues. However, its superficial location is rare. It sometimes takes on an appearance that leads to confusion. In these rare clinical forms, its diagnosis is not often considered. Case presentation: We report a case of myxoid liposarcoma of the bladder with rare exophytic development. It developed around a cystostomy tube. The diagnosis was made after histological examination of a biopsy of the mass. Excision of the mass combined with radiotherapy was proposed. The mutilating nature of the treatment prevented it from being carried out. The course was negative. Conclusion: This atypical mode of revelation may be a source of diagnostic delay.
