A Case Report on Pyodermatitis-pyostomatitis vegetans (PD-PSV) in a patient with ulcerative colitis

Pyodermatitis-pyostomatitis vegetans (PD-PSV)), is a very rare, chronic inflammatory dermatosis. It is characterized by large exudative, verrucous plaques with well-defined and elevated borders with typical mucocutaneous involvement. Cutaneous lesions can affect the genital and axillary areas, trunk as well as the scalp. Mucosal involvement is characterized by multiple pustules and vesicles on an erythematous base. Oral mucosa is mostly affected. PV(Pyoderma Vegetans) often affects middle-aged men. It is frequently associated with ulcerative colitis (UC), being considered a marker of inflammatory bowel disease (IBD). Predisposing factors include microbial infections, halogen ingestion, foreign materials and tattoos in patients with a compromised immune system.
