Bullous leukemia cutis in a patient with T-cell prolymphocytic leukemia

LC: leukemia cutis T-PLL: T-cell prolymphocytic leukemia L eukemia cutis (LC) is a rare, cutaneous infiltration of neoplastic leukemic cells and correlates strongly to additional sites of extramedullary disease. LC is a nonspecific term for the cutaneous manifestations of many subtypes of leukemia; therefore, the cutaneous morphology and histopathology of LC varies widely. This distinction makes it clinically difficult to distinguish from other nonspecific lesions, especially in the bullous subtype, which is rare and clinically mimics bug bites. LC usually follows or occurs concomitantly with the diagnosis of leukemia, and its presence is an indicator of poor prognosis Proper diagnosis of LC is essential because it can alter a patient’s treatment course.
