Pyoderma gangrenosum in association with hematologic malignancies: Systematic review
Pyoderma gangrenosum (PG) is a sterile, idiopathic, ulcerative, neutrophilic dermatosis that can be associated with trauma or systemic diseases. The lesion typically begins as a pustule that later progresses to an ulcer or deep erosion with violaceous undermined borders. Diagnosis of PG is based on histopathology as well as exclusion of other diagnoses. Approximately 50% of PG cases are associated with systemic diseases, which include inflammatory bowel disease (IBD), rheumatoid arthritis, and hematologic malignancies.
