Abstract

Large granular lymphocytic leukemia refers to a clonal expansion of lymphocytes that have abundant cytoplasm and azurophilic granules. The disease is characterized clinically by chronic neutropenia and it may be associated with recurrent pyogenic infections. Except for these infections, cutaneous manifestations of this disease have not been well characterized. We describe a patient with large granular lymphocytic leukemia, which was confirmed by molecular genetics studies, who had a pyoderma gangrenosum-like ulcer on his leg. Results of an evaluation of the histologic characteristics and the leukocytic immunophenotype of a skin biopsy specimen from the ulcer demonstrated large granular lymphocytes within the blood vessels. Cutaneous ulceration may be a manifestation of large granular lymphocytic leukemia, and this disease should be considered when diagnosing patients with otherwise unexplained pyoderma gangrenosum-like ulcers of the skin.
