[Acute intestinal obstruction provoked by intraperitoneal secretion of ovarian tumor. A clinical case].

We report here of the case of a 53-year-old woman who presented with intestinal obstruction without response to medical treatment. Exploratory laparotomy produced a moderate quantity of yellowish-green liquid and agglutination of semi-dough-like material. Separation of the flaps of intestine and colon was easily done by the fingers. A grayish white mass of 10 x 15 cm was seen in the left annex, with a perforation which released the semi-dough-like material. Wide resection of the corresponding annex was carried out. Anatomopathologic examination revealed malignant thecoma with resected free borders of at least 2 cm which was moderately differentiated. Because endometrial biopsy was normal, we decided against further hysterectomy. The patient was referred to an oncologist who did not recommend chemotherapy. The patient was reviewed one year later and was found to be free of tumor and in good condition although with some evidence of occlusive blocking. There have been only four similar cases in the literature in which intestinal obstruction by the same mechanism appeared, also indicating that the finding of malignant thecoma is rare.
