T-cell prolymphocytic leukemia (T-PLL) is the most common mature T-cell leukemia (MTCL). Cutaneous involvement is a characteristic symptom of T-PLL and appears in up to one-third of cases; however, T-PLL is a relatively unknown disease in the field of dermatology. In this article, we seek to increase awareness and educate physicians about the clinical manifestations of T-PLL. Hopefully, an increased awareness of this disease will lead to more prompt diagnoses and better prognoses for affected patients.
