Récidive d'un pseudomyxome péritonéal avec métastases hépatique et splénique: à propos d'un cas rare avec revue de littérature

Abstract

Pseudomyxoma peritonei (PMP) is a clinicopathologic syndrome characterized by mucinous ascites and pools of mucin resulting in neoplastic mucinous epithelium in the peritoneal cavity. PMP is uncommon and it is characterized by clinical and unusual pathologic manifestations posing diagnostic and therapeutic problems. Involvement of abdominal viscera and lymph node metastases are rare and sporadic cases have been reported in the literature. We here report the case of a 56-year old patient who had undergone two operations for PMP of appendicular origin presenting with progressive abdominal pain five years after his last treatment. Scanner objectified a recurrence of peritoneal pseudo-myxoma with liver and splenic intraparenchymatous lesions. Anatomopathological examination showed intrasplenic and hepatic recurrence of low-grade peritoneal pseudo-myxoma confirming the metastases.

Keywords: Peritoneal pseudo-myxoma, splenic metastasis, liver metastasis
