Nonhealing Ulcer at a Surgical SiteA man in his 80s was evaluated for a 4.5 cm necrotic ulcer with a violaceous border at a previous surgical site (Figure 1). The nonhealing ulcer despite treatment was concerning for squamous cell carcinoma (Marjolin ulcer). Punch biopsy from the ulcer border revealed epidermal hyperplasia with intraepidermal acantholysis, dermal hemorrhage, and lymphoplasmacytic inflammation (Figure 2). Tissue cultures, Grocott methenamine silver, Gram, and acid-fast bacillus stains and immunohistochemistry for herpes simplex virus were unremarkable.
Vulvar Lymphangioma Circumscriptum Secondary to Crohn DiseaseA 56-year-old woman presented to the dermatologist for worsening vulvar papules and edema for 3 years. She had Crohn disease in remission status post colectomy with ileostomy and vaginal fistula repair. Prior nondiagnostic biopsies performed by the gynecology service showed squamous hyperplasia, lichenoid features, acute and chronic inflammation, and dermal fibrosis. The labia were markedly edematous, with clear to hemorrhagic papules and vesicles coalescing to a papillomatous plaque (Figure 1).
