Rhinocerebral mucormycosis diagnosis by aspiration cytology.

Abstract

Rhinocerebral mucormycosis is a rapidly progressing, often fatal fungal infection that occurs commonly in diabetics and immunocompromised individuals. We present 2 cases of rhinocerebral mucormycosis with a paranasal mass. One patient had an intracranial extension. Nasal scrapings and fine-needle aspiration cytology (FNAC) of the paranasal masses showed fungal hyphae morphologically resembling Mucor. Surgical material showed features of mucormycosis. FNAC and scrape smears can give a conclusive diagnosis of mucormycosis, and the patient can be treated with appropriate antifungal therapy and surgical debridement. Preoperative cytology is an effective technique to establish a diagnosis of mucormycosis and obviates the need for a preoperative biopsy.
