Pyodermatitis-pyostomatitis vegetans (PD-PSV) is a rare disorder characterized by mucocutaneous involvement and associated with inflammatory bowel disease. We describe here a 42-year-old woman with ulcerative colitis who manifested verrucous and pyogenic lesions on her scalp, neck, axillae, inguinal areas, umbilicus, trunk, and oral cavity for about 11 months. She also experienced general fatigue and swelling in her lower extremities. Histology revealed eosinophilic inflammation with microabscesses and pseudoepitheliomatous hyperplasia, but she was negative on direct immunofluorescence for IgA, IgG, and C3. She was diagnosed with PD-PSV and treated with infusions of 100 ml 20% human albumin for five days, followed by 40 mg/day methylprednisolone, with remission of lesions observed after one month. We discuss the differential diagnosis of PD-PSV and pemphigus vegetans.
