Case in brief
A 38-year-old woman with advanced HIV infection presented with a vulvar lesion suggestive of carcinoma. Histopathology, fungal culture and molecular testing confirmed vulvar infection with Histoplasma capsulatum var. duboisii. She received antifungal therapy and had a favorable outcome.
What made this case unusual
The infection presented as a lesion resembling vulvar carcinoma, illustrating how genital histoplasmosis can mimic neoplastic disease.
Diagnostic / clinical pearl
In an immunocompromised patient with a suspicious vulvar lesion, include histoplasmosis in the differential and use tissue examination with microbiological and molecular testing to establish the diagnosis.
