Abstract
Primary cutaneous diffuse large B‐cell lymphoma is an uncommon and aggressive lymphoproliferative disorder with a rapid growth rate and dismal prognosis. We present the case of a 91‐year‐old female with an unusual manifestation of primary cutaneous diffuse large B‐cell lymphoma, mimicking other more prevalent diseases like chronic non‐healing venous ulceration. Dermatopathologic evaluation rendered the correct diagnosis. A discussion of this rare presentation is important for clinician consideration to prevent misdiagnosis and prolongation of proper management in patients with chronic non‐healing leg ulcers.
