Abstract

Pyoderma gangrenosum is a neutrophilic dermatosis that may be associated acute leukemia. We report a case of pyoderma gangrenosum associated refractory acute biphenotypic leukemia wherein the malignant cells show a phenotype specific for myelogenous and lymphocytic leukemia. Histopathologic examination revealed moderate perivascular infiltrate consisting mainly of neutrophils and lymphocytes without involvement of leukemic cells in the skin lesions. Treatment with systemic steroid was followed by a characteristically rapid healing of the skin lesions.
