Pyoderma gangrenosum associated with an aseptic splenic abscess in a patient with neurofibromatosis.

Pyoderma gangrenosum (PG) is a painful, ulcerating neutrophilic dermatosis commonly associated with a variety of underlying systemic conditions. We report a child with neurofibromatosis-1 (NF-1) and an aseptic splenic abscess who developed multifocal PG in areas of iatrogenic skin trauma. There is no clinical evidence or theoretical basis to suggest a causal relationship between NF-1 and PG. Systemic corticosteroid and cyclosporine therapy led to complete resolution of the lesions.
