A Case of Pyodermatitis-Pyostomatitis Vegetans

Autoimmune Disease Manifestations in the Oral Cavity

Immune-related disorders of the oral cavity may occur as primary disease process, secondary to systemic disease or neoplasm, or as a reaction to medications and other agents. The entities represented within this group may vary significantly by severity, clinical presentation, microscopic presentation, and special testing results. The selected immune-related conditions of the oral cavity in this article are categorized and presented by their prototypical tissue reaction patterns: vesiculobullous, including acantholytic and subepithelial separation; psoriasiform; spongiotic; and lichenoid reaction patterns.

Pyodermatitis vegetans after total colectomy

Pyostomatitis-pyodermatitis vegetans (PPV) is a rare dermatological manifestation of inflammatory bowel disease, characterized by erythematous, vesiculopustular, exudative, annular, and/or vegetating plaques over the intertriginous regions that may precede or appear at the same time as the mucosal lesions. Systemic corticosteroids, dapsone, sulfasalazine, azathioprine, cyclosporine, and subtotal/total colectomy are the most common treatment options. A 16-year-old male patient presented to our outpatient clinic with a four months history of thickly crusted erosions on his trunk, back, and lower extremity. He had ulcerative colitis for four years and total colectomy was done seven months ago. Clinical and histopathological examination of his lesions were consistent with pyostomatitis vegetans. Although subtotal/total colectomy has been reported as a treatment option for PPV, lesions reappeared three months after total colectomy in our patient.

Pyoblepharitis Vegetans in Association With Pyodermatitis-Pyostomatitis Vegetans

Background:

Pyodermatitis-pyostomatitis vegetans (PDPSV) is a rare inflammatory disorder of the skin and oral mucosa that is commonly associated with inflammatory bowel disease (IBD). Ocular involvement is uncommon.

Objective:

Given the association with IBD, it is important for dermatologists to be aware of the varying manifestations of PDPSV.

Methods:

A biopsy was performed for diagnosis confirmation, and the literature was reviewed for similar cases.

Observations:

Our 48-year-old PDPSV patient presented with rare ocular findings. There have been 8 PDPSV reports of ocular involvement. Only 3 of those patients developed blepharitis and/or conjunctival disease. None showed simultaneous involvement of sites at disease onset like our patient.

Results:

Our patient’s concomitant presentation at onset of multiple mucocutaneous sites with blepharitis and conjunctivitis is unique.

Conclusions:

We propose the term pyoblepharitis vegetans (PBV) to describe vegetating lesions of the eyelids. The diagnosis of PDPSPBV should be considered with presentation of these signs.
