Early diagnosis of polymyalgia rheumatica is often difficult. A missed diagnosis and inadequate treatment can result in severe and prolonged disability and expose the patient to the hazards of temporal arteritis. Treatment is effective and relatively straightforward provided that good doctor-patient communication is maintained.
The development of a reticulum cell sarcoma in the lung of a patient with systemic lupus erythematosus treated with azathioprine for 18 months is described. This possible hazard of immunosuppressive therapy is discussed in relation to patients with SLE.

A patient with systemic lupus erythematosus (SLE) was treated with chloroquine therapy for four years after the onset of her illness. Nine years after cessation of chloroquine, muscle weakness developed as part of the SLE. Four muscle biopsies performed for diagnostic purposes revealed varying degrees of inflammatory change as well as distinctive cytosomes with curvilinear profiles (CCPs). These CCPs were identical to those reported in Batten disease, a degenerative disorder of children which has a clinical course different from SLE. The CCPs seen in this case of SLE are thought to result from the effect of chloroquine on membrane systems within muscle cells. This report calls attention to the fact that CCPs are not unique to Batten disease bu may also occur in muscle of SLE patients treated with chloroquine.
