Indurated Plaques on the Legs: Think Lymphoma

Primary cutaneous diffuse large B-cell lymphoma, leg-type (PCDLBCL-LT) is a rare and aggressive neoplasm. A timely diagnosis may prevent fatal outcomes; physicians should take this entity into consideration when assessing non-specific lesions on the lower limbs. We present a 69-year-old woman with a 1-month history of a firm plaque on her left leg. Physical examination revealed an asymptomatic, indurated, smooth, and erythematous plaque on the pretibial region of her left extremity (Figure 1,a)
