²Ankara Numune Training and Research Hospital Pathology, ANKARA Pyoderma vegetans, also known as pyodermatitis vegetans, is a rare inflammatory dermatosis characterized by vesiculopustular lesions and vegetating plaques most commonly affecting the scalp, trunk, flexural areas and extremities. The etiopathogenesis of pyoderma vegetans has not been clearly elucidated yet; however, it has been proposed that pyoderma vegetans is associated with a number of underlying conditions, including ulcerative colitis, cutaneous T-cell lymphoma primary immunodeficiency, alcoholism and human immunodeficiency virus infection. Although pyoderma vegetans may also be seen in healthy individuals, considerable association between immunosuppression and pyoderma vegetans is evident. Moreover, the occurrence of pyoderma vegetans and its oromucosal analogue, pyostomatitis vegetans, has been reported to be as high as 75% in patients with inflammatory bowel disease; hence, pyoderma vegetans has been considered to be an indicator of inflammatory bowel disease. On the other hand, the association of pyoderma vegetans with CrohnÂ’s disease has been rarely documented, and most of the reported cases are associated with ulcerative colitis. Here, we present a case of pyoderma vegetans associated with CrohnÂ’s disease that showed remarkable response to corticosteroid therapy.
