Alternaria alternata infection associated osteomyelitis of maxilla: A rare disease entity.

Alternaria alternata is one of the rarest fungi associated with paranasal sinusitis. Alternaria species are pigmented (also known as dematiaceous or phaeoid) filamentous fungi, which are well-known soil saprophytes and plant pathogens that infrequently cause infection in humans mainly, cutaneous lesions. We present a case of osteomyelitis of maxilla caused by a rare fungus- A. alternata in a diabetic patient with poor glycemic control who was successfully treated with antifungal and surgical debridement over the period of 6 months.
