Pseudomyxoma peritonei: A case report and review of the literature.

OBJECTIVE: We present the case of a patient incidentally diagnosed with a pelvic mass next to the bladder. After surgical excision, definitive diagnosis was pseudomyxoma peritonei. We provide a concise review of the literature of this pathology. METHODS: A 55 year-old male patient, was found to have, in annual routine ultrasound, a pelvic retrovesical mass. CT guided needle aspirate showed a tumor with myxoid changes and low aggressive cytology. Surgical excision was performed. RESULTS: The excised mass contained the cecal appendix and ileal serosa. Pathology report was: mucinous cystadenoma of the appendix and pseudomyxoma peritonei. CONCLUSIONS: PMP is a local-regional disease within the abdomen, characterized by a mucinous tumor (mucocele) that produces a progressive amount of mucinous ascites, which eventually blows-out, and tumor cells are spread through the peritoneal cavity. Treatment options differ significantly, depending the stage of the disease.

Objetivo: Presentamos el caso de un paciente diagnosticado incidentalmente de una masa pélvica lateral a la vejiga. Después de realizarse cirugía de extracción de la masa, el diagnóstico fue de pseudomixoma peritoneal (PMP). Métodos: Un paciente varón de 55 años de edad, en ecografía rutinaria presenta una masa pélvica retrovesical. Punción y aspiración guiada por TAC mostró un tumor con cambios mixoides y citología de baja agresividad. Se realzó cirugía y extracción de la masa. Resultados: La pieza quirúrgica contenía además el apéndice cecal y serosa ileal. El reporte de patología fue: cistoadenoma mucinoso del apéndice y PMP. Conclusiones: PMP es una enfermedad loco-regional del abdomen, caracterizada por un tumor mucinoso (mucocele) que produce una cantidad progresiva de ascitis mucinosa, que eventualmente revienta, y las células malignas son esparcidas en la cavidad peritoneal. Las opciones de tratamiento difieren significativamente según el estado de la enfermedad (AU)
