[Phenothiazine-induced pseudolymphoma].

A 59-year-old male patient developed lymphoma-like cutaneous infiltrates on the back and left side following treatment with levomepromazine (Neurocil) over many years. Complete remission after discontinuation of levomepromazine and its replacement by a drug of another chemical class (melperone, Eunerpan) confirmed the causative role of the phenothiazine in the development of pseudolymphoma.
