Coexistent systemic lupus erythematosus and tophaceous gout.

Only seven patients with coexistent gout and systemic lupus erythematosus have been reported in the English-language literature. We describe an eighth case, which is the first, to our knowledge, in the dermatologic literature. The patient met four of the eleven new American Rheumatism Association criteria for the diagnosis of systemic lupus erythematosus, and clinical, laboratory, roentgenographic, and histologic assessments confirmed the diagnosis of gout.
