Pyoderma-Pyostomatitis Vegetans without Inflammatory Bowel Disease / 대한피부과학회지

ABSTRACT

Pyodermatitis-pyostomatitis vegetans (PD-PSV) is a rare, benign pustular and vegetating mucocutaneous dermatosis with a tendency to affect the oral mucosa and the skin of the groin and axilla. The cutaneous lesions begin as crusted erythematous papulopustules, which coalesce to form large vegetating plaques, usually in the axillae, genital area and scalp. PD-PSV is known to be frequently associated with inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease. We report a rare case of PD-PSV, which showed typical clinical and istopathological features, but was not accompanied by inflammatory bowel disease.
