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.
