An unusual case of keratin granuloma peritonealis following spontaneous rupture of mature ovarian cystic teratoma: A case report and discussion

Abstract

Mature ovarian teratoma is a common benign tumour in women of reproductive age group. This is a slowly growing tumour
often remains asymptomatic for a long period of time unless large sized or some complication occurs. Torsion is the most
common complication, whereas rupture is an unusual complication of mature teratoma. We report a case of keratin granuloma
peritonealis, a very rare condition following spontaneous rupture of mature ovarian teratoma. Rarity of this condition warrants
its mention.
A 40 year old female presented with an acute abdomen with the background history of gradually increasing abdominal pain
and distension for three months. She had exploratory laparotomy which revealed keratin granulomas and chemical peritonitis.
The diagnosis of spontaneously ruptured teratoma was made. The abdomen was closed following rigorous peritoneal washout.
After an interval of 8 weeks, left adenexectomy and adhesiolysis were performed. She made full recovery after the surgery.
