[Peritonitis caused by a giant trichobezoar ventriculi--a case report].

Bezoars are the most common foreign bodies of gastrointestinal tract. They contain swallowed hair, different fibres, seeds, nut shells, sweets or drugs. Clinical manifestations vary, depending on the location and size of bezoar, from "no symptoms" to "acute abdomen" syndrome. In this case report, the authors describe a giant trichobezoar from the stomach of an 18-year-old girl, who had been admitted to the gynecological department with syndromes suggesting an ovarian cyst torsion. The preoperative diagnosis was not confirmed and a giant trichobezoar was found and removed during the surgery.
