Fibroma of the cecum. Case report.

The case of a young woman with pain and a tumor in the right lower abdomen is reported. Ultrasound revealed an echogenic tumor of 10 cm diameter. Fibroma of the uterus was diagnosed. During the operation in the gynecological department, the tumor turned out not to be of gynecological origin. After more extensive examinations laparotomy was performed. Histologic examination of the tumor revealed a fibroma, originating from the muscular layer of the cecum. In the literature of the last 35 years, only 5 similar cases have been reported and in 2 of them it was also misdiagnosed as fibroma of the uterus.
