title: Local foreign body reaction of peritoneum after rupture of cystic partially immature teratoma.
abstract: This is a pictorial report of rare sequelae after an unintended intraoperative rupture of a cystic teratoma. A 30-year-old woman was operated on for a mature cystic teratoma of the right ovary with an unintended intraoperative rupture of the ovarian tumor during the procedure. Postoperatively, the final immune histologic report showed partial neuroendocrine differentiation of an immature origin. At relaparoscopy for staging 7 weeks later, several suspicious peritoneal lesions of up to a 2.5-cm diameter were discovered and excised for which malignancy could not be excluded macroscopically. However, the final histologic report revealed a foreign body reaction related to spilling of the content of the mature teratoma. It is important to distinguish local peritoneal reaction from chemical peritonitis. The postoperative follow-up regarding symptomatic recurrence was uneventful.
