[Gastroduodenal trichobezoar: about a case].

Gastroduodenal trichobezoar ulcer is rare. Its diagnosis is easy in the presence of an evocative context. We report the case of a 21-year old patient followed up for schizophrenia, admitted with acute abdominal pain, vomiting and epigastric mass. Abdominal CT scan suggested the diagnosis of bezoar on the basis of heterogeneous, non-enhanced lesions occupying the entire stomach and appearing to be separated from the gastric wall. Surgical removal of trichobezoar by gastrotomy was performed without complications. The patient was referred to the Department of Psychiatry.
