Twenty-five patients had superficial ulcerative and vegetative pyoderma with
granulomatous histologic findings. Healing occurred without systemic
corticosteroid therapy in all but three patients. All patients had clinical
pyoderma gangrenosum. In five patients the lesion occurred after surgery of the
skin. Histopathologic study of 40 biopsy specimens showed focal neutrophilic
abscesses of the papillary dermis, often with peripheral palisading histiocytes
and foreign-body giant cells. Pseudoepitheliomatous, vegetative hyperplasia and
sinus tract formation were observed frequently. All patient had massive areas of
plasmacytosis, and 13 had eosinophils. Granulation tissue, hemorrhage, and
fibrosis were additional features in some areas. Foreign material in the lesions
was considered unimportant, except in one patient with a starch granuloma.
Therapy with local corticosteroids, minocycline, tetracycline, or sulfa drugs
resulted in healing in 15 patients. We believe that we have identified a
localized, limited form of chronic superficial pyoderma gangrenosum with
verrucous and ulcerative lesions and a granulomatous histologic appearance that
represents a unique pattern of this disease in some patients.
