Pseudomixoma Peritonei as an Unusual Tumor in a Kidney Donor

Abstract

Introduction: Pseudomixoma peritonei is a neoplasia originating from the appendix, with an incidence of 2-4 per million habitants. Clinical presentation is variable, from asymptomatic to appendicitis, intestinal obstruction, or perforation, and is usually diagnosed incidentally at image studies or by laparoscopy when performing a conventional appendectomy. Case presentation: 40-year-old male with history of successful left kidney donation developed a pseudomixoma peritonei. At image examination, a CT revealed hypermetabolic activity consistent with peritoneal carcinomatosis, treatment with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy was established with good results and has been followed up for 4 years with no evidence of recurrent disease and adequate kidney function. Conclusion: Association of appendiceal neoplasms in organ donors has been unusual when developed most common present as carcinomatosis, combined treatment with cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy has shown the best long-term survival for appendiceal neoplasms.
