Inflammatory Myositis-Secondary to SLE.

Inflammatory myositis involving the proximal muscles has been reported to occur in 5% to 11% of SLE patients and may develop at any time during the course of the disease. It can be secondary to internal malignancies also. We report one such patient who presented with generalised muscle weakness for 7 months. Erythematous hyperpigmented scaly patches were present over the scalp, face, trunk, upper limbs. We discuss the inflammatory myopathies secondary to SLE and internal malignancies. Most cases responds to low-dose corticosteroid treatment.
