Pyoderma gangrenosum in a patient with essential thrombocythemia

BACKGROUND: Pyoderma gangrenosum is an uncommon ulcerative condition associated with inflammatory bowel disease, arthritis, and hematologic disease. We report a patient with essential thrombocythemia and pyoderma gangrenosum. OBJECTIVE: This article is a review of the associations between pyoderma gangrenosum and other diseases. RESULTS: There have been two previous reports of patients with pyoderma gangrenosum and essential thrombocythemia. CONCLUSION: There may be a possible association between pyoderma gangrenosum and essential thrombocythemia. The diagnosis of pyoderma gangrenosum should be considered in patients with essential thrombocythemia and cutaneous ulcers.
