[Pseudomyxoma peritonei with appendiceal and ovarian mucinous cystadenoma. A case report. Correlations with synchronous or metachronous colorectal carcinomas].

Mucocele is a rare pathology which is difficult to diagnose prior to surgery. The clinical symptoms are aspecific. Diagnosis is generally made at the time of surgery. Explorative laparoscopy is not advised owing to the possibility of encouraging metastatic diffusion. Surgery associated with ex tempore freezer tests must be carried out with the greatest caution to avoid rupture of organs and the spread of mucin. Appendectomy and removal of the adnexa is recommended in benign forms, with or without omentectomy. Omentectomy is necessary together with hystero-adnexectomy and right hemicolectomy in malignant forms, as well as lymph node cleaning and removal of all mucin in pseudomyxoma peritonei.
