An unusual cause of acquired tracheo-oesophageal fistula in a patient undergoing chemotherapy

Fungal infection is a common complication following intensive chemotherapy for acute myeloid leukemia. Fungal infections commonly involve the lungs, paranasal sinuses or the skin. Our patient was evaluated for complaints of a choking sensation in the throat, and was found to have a trachea-oesophageal fistula with an eroding growth, which on biopsy was proven to be mucormycosis. Even with unusual presentation such as this, a high index of suspicion for an infective etiology is required in patients following high dose chemotherapy.
