title: A Case of Intermittently Discharging Skin Lesion: Orodentocutaneous Fistula Demonstrated on CT Fistulography.
abstract: Orodentocutaneous fistula is a rare entity where periapical dental abscess communicates with both oral cavity and external skin. In few cases, patients presents initially with only cutaneous manifestation with no recollectable history of dental problem. Delay in diagnosis of odontogenic cause of skin lesion makes the disease more chronic and extensive. We hereby present a case of orodentocutaneous fistula that presented with intermittently discharging skin lesion and was evaluated by using CT fistulography.
