A case of pyoderma vegetans associated with acne conglobata

Pyoderma Vegetans

Background:

Pyoderma vegetans is a rare condition that is clinically characterized by large verrucous plaques with elevated borders and multiple pustules. The etiology of this disorder remains unknown.

Objectives:

We describe a 24-year-old woman with rapidly evolving pyoderma vegetans. Our patient had the unique additional findings of a highly elevated serum IgE level and a history of hidradenitis suppurativa.

Conclusions:

Pyoderma vegetans is diagnosed on clinical and histological criteria. Differentiation must be made from disorders such as pyoderma gangrenosum, Sweet's syndrome, and deep fungal infections. We illustrate a case of pyoderma vegetans and review the literature on this rare disorder. Clinical and histological criteria for diagnosis are presented, as well as differentiation from some mimicking disorders.

A case of pyoderma vegetans and the follicular occlusion triad

A case of pyoderma vegetans (PYV) and hidradenitis suppurativa (HS) is described. Our patient had a previous history of perifolliculitis capitis abscedens et suffodiens and acne conglobata. Direct immunofluorescence findings ruled out pemphigus vegetans and suggested a potential pathogenic mechanism.
