In the present study we report a patient with long-standing seropositive rheumatoid arthritis, who developed Crohn's disease. We discuss the possible pathophysiologic mechanisms and their associations between these two entities.

Endometriosis of the sigmoid colon is a pathologic entity which is infrequently reported. A 29-year-old woman was admitted to the hospital because of abdominal pain, constipation, and menstrual rectal bleeding. Endometriosis was suspected, and CT (virtual) colonoscopy showed severe stenosis of the orthosigmoid canal due to a submucosal mass. Sigmoidoscopy using a pediatric endoscope was successful, and biopsies confirmed the original diagnosis. Non-invasive techniques such as endoscopic ultrasound and CT (virtual) colonoscopy now make it possible to diagnose sigmoid endometriosis. The latter technique, in particular, is feasible and well tolerated.
