Abstract
Gout is a systemic disorder characterized by hyperuricemia and recurrent arthritis, most involvement of ankles, midfoot joint and first metatarsophalangeal joint, with monosodium urate crystals deposition in synovial fluid and other tissues. We present a case of 53-year-old male, who had several nontender, white-yellow papules and plaques over his elbows, knees and arms with chalk-like substances and crust on inflammatory base wax and wane in the past 2 years. Upon histopathology examination of the skin lesions, it reported as intradermal urate tophi and miliarial gout was diagnosed. This case highlights the importance of considering unusual cutaneous tophi in the differential diagnosis of deposition disorders.
