Acute psychosis in an adolescent girl during treatment for advanced nodular lymphocyte-predominant Hodgkin's lymphom.

A 16,5 year old female adolescent was diagnosed with nodular lymphocyte-predominant Hodgkin lymphoma (nLPHL), presenting bilateral inguinal and right iliac lymphadenopathy accompanied by B-symptoms. The patient was due to treatment according to the German Interim Guidelines of HD 2002-Pilot Study with 2x OPPA (vincristine, adriamycine, prednisone, procarbacine) and 2x COPP (cyclophosphamide, vincristine, prednisone, procarbazine) and radiotherapy. After 2x OPPA the patient presented a severe episode of a presumably prednisone-induced acute psychosis with need for psychiatric treatment and change of therapy regimen. She was successfully treated with a chimeric monoclonal anti-CD20 antibody (rituximab) and subsequent radiotherapy.
