  4. Pyodermatitis-pyostomatitis vegetans is a rare but characteristic pustular eruption of the mouth and skin folds consistently associated with inflammatory bowel diseases such as ulcerative colitis and less commonly Crohn disease. The skin disease is pyodermatitis vegetans and the mucosal disease is pyostomatitis vegetans
  5. Pyostomatitis vegetans (PSV)-pyodermatitis vegetans (PDV) is a rare inflammatory mucocutaneous disease strongly associated with inflammatory bowel disease (IBD), particularly ulcerative colitis (UC). 1, 2 The cutaneous manifestations of this disease are referred to as pyodermatitis vegetans and the oral form is termed pyostomatitis vegetans, although most reports support the notion that they are virtually the same disease because they have similar histopathological features.
  6. Pyostomatitis vegetans is an uncommon manifestation of inflammatory bowel disease, with most cases being associated with ulcerative colitis. Some patients with Crohn disease may also present with pyostomatitis vegetans. A similar skin condition, known as pyodermatitis vegetans, may develop simultaneously in some instances

Pyostomatitis Vegetans is a rare, pustular, oral condition associated with inflammatory bowel disease and other underlying gastrointestinal diseases. The gastrointestinal diagnosis typically precedes the oral diagnosis by years. This is the oral presentation of pyoderma vegetans (vegetative plaques in the intertriginous folds) • Pyostomatitis vegetans is a rarely occurring disorder of the oral mucosa, which has a dramatic clinical picture and a striking histopathologic pattern. Moreover, the condition is a highly specific oral mucosal marker for inflammatory bowel disease, particularly ulcerative colitis BACKGROUND: Pyostomatitis-pyodermatitis vegetans is an uncommon condition associated with chronic inflammatory bowel disease in 75% of the cases, usually hemorrhagic rectocolitis.

Pyostomatitis vegetans (PV) is a rare inflammatory stomatitis that is seen in association with inflammatory bowel diseases (IBD). The treatment approach of PV depends on the presence of coexisting IBD. In the absence of IBD, topical steroids are often used, but in many cases, there is a need for systemic therapy Direct immunofluorescence was negative. Conclusion: Pyodermatitis-pyostomatitis vegetans is a rare disorder of unknown cause.

In particular, pyostomatitis vegetans must be excluded in patients presenting with oral involvement.

Benign and reactive lesions (e.g. squamous papilloma, verruciform xanthoma) usually present little diagnostic difficulty. However, premalignant and malignant verrucous and papillary lesions pose a much greater diagnostic challenge, not helped by often confusing terminology Pyostomatitis vegetans is rare.
