A small number of cases have been presented in the world literature in which treatment with phenothiazines resulted in clinical and laboratory manifestations of systemic lupus erythematosus (SLE). The clinical picture of such patients tends to be "symptom poor". A 26-year-old patient is presented who had a 7-year history of treatment for a schizophrenic illness and developed clinical as well as laboratory evidence for SLE. The differential diagnosis included: a) phenothiazine-induced SLE; b) SLE presenting with psychosis as a symptom; and c) SLE and sychosis occurring independently. The patient had a complete medical and neuropsychiatric work-up and was followed for 12 months. This challenging diagnostic problem is discussed. Phenothiazine-induced SLE was the most likely diagnosis. Although the possibility of two diseases occurring independently in the same person did not explain the clinical and laboratory data, it is difficult to rule out this possibility completely. SLE presenting with psychosis as a symptom could be ruled out by the work-up and history.

Phenothiazine-induced lupus with circulating anticoagulant (CAC) has been reported infrequently, and is rarely associated with significant symptoms. We describe a patient who we suspect had perphenazine-induced lupus erythematosus with CAC. She had recurrent episodes of venous thrombosis and ultimately developed superior vena cava syndrome. The relationships among phenothiazine-induced lupus, CAC, and thrombosis are discussed.
