Fig 2 Skin of back. A, The periphery of the ulcer undermines adjacent skin and is partially re-epithelialized. B, The ulcer bed harbors acute suppurative and plasma cell–rich inflammatory components. The histologic features are consistent with pyoderma gangrenosum. (Hematoxylin-eosin stain.)

Fig 5 Naris lesion. A, Acute suppurative folliculitis with rupture and destruction of a follicular infundibulum. B, In the context of the skin of back lesion, the acute suppurative folliculitis at the naris probably denotes an early lesion of pyoderma gangrenosum. (Hematoxylin-eosin stain.)
