Less Common Vulvar Dermatologic Diseases.

Less common vulvar dermatologic disorders discussed here can mimic infection, inflammatory dermatoses, and malignancy. This review outlines 4 entities clinicians should recognize. A pyogenic granuloma is a benign, rapidly growing vascular neoplasm that bleeds easily; excision is typically curative. Hidradenitis suppurativa causes recurrent nodules, sinus tracts, and scarring. Diagnosis is clinical with multimodal management using antibiotics, biologics, and surgery. Aphthous ulcers are a diagnosis of exclusion, with treatment centering on analgesia and anti-inflammatory therapy. Vulvar Crohn disease is rare, often diagnosed late, and managed with biopsy plus coordinated dermatology-gastroenterology care. Recognizing these dermatoses is imperative for timely diagnosis and management.
