History

Some patients with pyoderma vegetans (PV) may have a history of hidradenitis suppurativa. [19, 20] This rare inflammatory dermatosis may involve skin and mucosa with pustular and vesicular plaques. In some patients, vegetating plaques may appear in the axillary, vulvar, and inguinal areas. [21] Disfiguring facial pyoderma vegetans has been described. [22]

Physical Examination

Both clinical and histologic findings are necessary to make the diagnosis of pyoderma vegetans. The plaques are often multiple; some may appear purulent, others hyperkeratotic. [23] At clinical examination, multiple pustules and large verrucous plaques with an elevated border are identified (note the images below). It may rarely appear on the penis. [24] At histologic examination, pseudoepitheliomatous hyperplasia is demonstrated.
