Gout - Cellulitis DDx
The acute form of gout presents as a painful, swollen, warm, and erythematous joint, usually monoarticular, with the most common joints affected being the first metatarsophalangeal joint, ankle, foot, and knee.
Chronic tophaceous gout presents most commonly involving the ear but can also affect other soft tissues, articular structures, bursas, or tendons. Smooth or multilobulated nodules can ulcerate, leading to extrusion of a chalk-like substance. Rarely, urate bullae may develop.
Men aged 40-50 are most commonly affected. Other risk factors include renal insufficiency, obesity, increased alcohol consumption, medications (eg, diuretics), lymphomas, leukemias, tumor lysis syndrome, and hemolysis as well as lead exposure (eg, from illegally distilled liquor, or "moonshine"; known colloquially as "saturnine gout").
Gout should be distinguished from cellulitis on the basis of involved body location and possible previous history of similar attacks. Gout does not spread like the plaques of cellulitis.
