[Intestinal endosalpingiosis. Apropos of 2 cases]

Intestinal endosalpingiosis (ES) involving colon or small bowel is a rare, misleading disease. Two different aspects must be distinguished:--serosal involvement, more or less disseminated: this form is asymptomatic or associated with ascites leading to the diagnosis of peritoneal pseudo-carcinomatosis; in this form of typical or atypical endosalpingiosis of florid type, no malignancy is found on histology;--parietal involvement, leading to stenosis or intestinal perforation with enterocutaneous fistula: this malignant form of endosalpingiosis is similar to primary papillary peritoneal carcinoma or stage III ovarian carcinoma. These two forms of ES are studied on 2 cases illustrating the overlap between typical benign ES, proliferating ES and malignant ES.
