Anorexia nervosa presenting as a somatic delusional disorder responsive to pharmacotherapy

A case of somatic delusional disorder with a severe secondary eating disorder is described. The patient's psychotic symptoms and emaciation were markedly improved with separate trials of antipsychotic and antiobsessional medications. Further epidemiologic studies of eating disorders with coexisting psychotic disorders are suggested. Classification of eating disorders to include a subset with psychotic or obsessional features (or both) may prove useful in future diagnoses. Pharmacotherapy may be a beneficial therapeutic modality in treating eating disorders with concurrent psychotic features.
