Dermoid perforation of the colon

Abstract

A case report of an ovarian dermoid tumor perforation the sigmoid colon in a pregnant woman is presentd. Various complications of dermoid perforation are discussed.

Ovarian dermoid presenting as acute intestinal obstruction: a rare case report and review of literature

“…8 In contrast, rupture, infection and secondary malignant change are uncommon complications and dermoid cysts only very rarely present with bowel involvement. In this regard, entero-ovarian fistulae have been described involving both the small [9][10][11] and large [12][13][14][15] bowel. Such patients may present with pain, rectal bleeding or the passage of dermoid cyst contents such as hair and teeth within the stool.…”

Mature Cystic Teratoma Eroding into the Colon

“…Ovarian dermoid cysts that perforate the bowel may result in hairy stools, acute abdominal pain, and perrectal bleeding. 1,2 In our patient, iatrogenic rupture of ovarian cyst during previous cystectomy was the likely cause of the dermoid cyst eroding into the colon, leading to intra-abdominal spillage of tumour contents. It then caused chemical peritonitis, resulting in an inflammatory reaction and adhesion to surrounding structures and erosion into the colon.…”

Two cases of ovarian mature cystic teratoma with bowel fistulation

“…Most commonly encountered causes for chronic dirrhoea would be irritable bowel syndrome (IBD), bile acid diarrhea, dietary related, colonic neoplasia, inflammatory bowel disease, and drug related [4] . Benign ovarian dermoid cysts are usually asymptomatic but occasionally complicate into ovarian torsion (16%), peritoneal rupture (1-4%), malignant transformation (1-2%) infection (1%), invasion into adjacent viscera and autoimmune hemolytic anemia (< 1%), producing variable symptoms [5][6][7][8][9][10] . Fistula formation is a rare complication of dermoid cysts.…”
