TWO CASES OF MUCOSAL PROLAPSE SYNDROME OF THE RECTUM

Abstract

Two cases of mucosal prolapse syndrome are reported. Case 1:40-year-old female with complete rectal prolapse were endoscopically diagnosed as submucosal tumor. Barium enema study showed a few elevated lesions which are about 1 cm in size. Histopathological study revealed this case as colitis cystica profunda. Case 2 : 34-year-old male had been complained of difficulty of defecation for many years. He had a habit of straining. Barium enema study showed filling defect, suspected of rectal malignancy. Endoscopic appearance showed enlarged rectal mucosa and ulcera-tion. Epithelial changes of rectal mucosa were not entirely clear. By histopathological study, this case was diagnosed as solitary ulcer of the rectum. In both cases, fibromuscular obliteration in lamina propria was observed. Therefore, we suppose, these two cases can be included in the entity of mucosal prolapse syndrome which were due to obvious rectal prolapse or a habit of straining as occult mucosal prolapse. According to the concept of this syndrome, it is important to confirm mucosal prolapse. But it is difficult to diagnose occult mucosal prolapse, so detailed questioning is necessary on concealed straining habit. Surgical therapy is effective in case of obvious rectal prolapse.
