The ulcers are most commonly painless and located on the trunk, with a clean granulating base. They generally do not show undermining but may have a vegetative border. Lesions usually respond well to either topical or intralesional corticosteroids with complete healing. The classic histopathologic finding is a "three-layer granuloma" in the superficial dermis consisting of central neutrophilic inflammation and necrosis, a surrounding layer of histiocytes and multinucleated giant cells, and an outer most layer of plasma cells and eosinophils. Herein, we present a unique case of SGP with sporotrichoid-like distribution on the lower extremity.Red puffy hand syndrome is an uncommon clinical manifestation of intravenous drug abuse, which presents with bilateral, painless and non-pitting erythema and edema of the dorsal hands. The pathophysiology is believed to primarily be the result of lymphatic blockage from either direct toxicity of the injected drug, drainage of impurities, or infection complications. A woman in her 40's with remote intravenous drug use presented with over a decade of fixed, painless erythema and swelling of bilateral dorsal hands. Owing to an elevated rheumatoid factor, which would later be attributed to patient's untreated hepatitis C, these findings were mistaken for rheumatoid arthritis and unnecessarily treated with methotrexate and prednisone. Upon proper recognition of her underlying Red puffy hand syndrome, systemic medications were discontinued and appropriate care was initiated with lymphedema decongestion and occupational therapy. Red puffy hand syndrome, albeit rare, is an important manifestation of intravenous drug abuse; its r
