Lupus erythematosus (LE) is separated into the systemic (SLE) and the cutaneous (CLE) forms of the disease. Patients with SLE experience constitutional symptoms such as fatigue, fever, and weight loss. They can be identified using either the ACR or SLICC criteria. Cutaneous LE presents with non-specific cutaneous lesions such as diffuse non-scarring alopecia, Raynaud phenomenon, nail fold telangiectasias and erythema, palmar erythema, papular and nodular mucinosis, vasculitis, Sweet-syndrome-like neutrophilic dermatosis, and cutaneous signs of APS.

This quiz is designed to test your knowledge on the epidemiology, pathogenesis, clinical features, differential diagnosis and management of LE. We encourage you to review the associated learning module before taking the quiz.
