Tuberculous fistulas of the pharynx and esophagus

Four patients with tuberculous fistulas communicating with the pharynx or the esophagus are reported. In 1 patient, there was strong evidence to suggest primary involvement of the esophageal mucosa. The other 3 cases were related to involvement of the pharynx or the esophagus from adjacent tuberculous process, as confirmed by histopathological proof.The patients had varying degrees of symptoms, which in two dramatically responded to antituberculous therapy; the third patient needed surgery for complete cure and the last patient was lost to follow-up.
