Pediatric pyoderma gangrenosum associated with leukocyte adhesion deficiency type 1: A case report and review of the literature

Abstract Pyoderma gangrenosum is a rare neutrophilic dermatosis characterized by painful skin ulcers with necrotic, undermined margins. In severe cases, particularly in pediatric patients, work‐up for an associated autoimmune, inflammatory, malignant, or genetic disorder should be considered based on the clinical presentation. We report a unique case of pediatric pyoderma gangrenosum with a leukemoid reaction, secondary to an autosomal recessive leukocyte adhesion deficiency type 1.
