Peripheral T-cell lymphoma with erysipelaslike spread.

An 88-year-old man from the Dominican Republic with a history of gastric adenocarcinoma was admitted with one month of fatigue, anorexia, weight loss, and abdominal pain. The dermatology department was consulted to evaluate an asymptomatic, shiny, firm, red nodule on the lower left chest, with an expanding rim of erythema. Skin biopsies were performed from the nodule and surrounding rim of erythema, which were both diagnostic of peripheral T-cell lymphoma (PTCL). This case is a unique example of PTCL with erysipelaslike spread.
