Sigmoidocele (also known as pouch of Douglas descent) is a medical condition in which a herniation of peritoneum containing loops of redundant sigmoid colon descends (prolapses) into the rectouterine pouch (in females), between the rectum and the vagina. [1] [2] This can obstruct the rectum and cause obstructed defecation syndrome. [3]
Oral submucous fibrosis (OSF) is a chronic, complex, premalignant (1% transformation risk) condition of the oral cavity, characterized by juxta-epithelial inflammatory reaction and progressive fibrosis of the submucosal tissues (the lamina propria and deeper connective tissues).
The sigmoid colon is completely surrounded by peritoneum (and thus is not retroperitoneal), which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.
Description: Another case of villous adenoma of the transverse colon, this one more discrete and polyp-like than the case above. Although it had a semi-decent stalk, it was still far too large for safe removal by endoscopy, so the surgeon was called in to do a segmental resection of the colon.
The final branch which is important for the digestive system is the inferior mesenteric artery, which supplies the regions of the digestive tract derived from the hindgut, which includes the distal 1/3 of the transverse colon, descending colon, sigmoid colon, rectum, and the anus above the pectinate line.

The cemento-ossifying fibroma is hard and fibrous, most frequently seen in the jaw or mouth, sometimes in connection with a fracture or another type of injury. Other fibromas: chondromyxoid fibroma , desmoplasmic fibroma , nonossifying fibroma , ossifying fibroma , nuchal fibroma , collagenous fibroma , fibroma of tendon sheath , perifollicular ...
Low grade dysplasia means that the tissue maintains the glandular structure, cellular variance (pleomorphism) is mild or absent, nuclei maintain basal polarity and mitotic activity is not markedly increased.
