[Odontogenic sinusitis with cutaneous fistulization. A case report]

A 70-year-old male patient presenting with a cutaneous node of the genal region that was first diagnosed as basal cell carcinoma is described. Owing to the following observation, the authors were prompted to a diagnosis of cutaneous odontogenic sinusitis: a) examination of the lesion which emitted pus upon gentle squeezing; b) presence in the vestibular fornix of a large fibrous cord; c) the serious conditions of the mouth and the radiologic results of homolateral sinusitis. The importance of the sinusitis picture, and the necessity to completely remove all bacteria foci prior to surgery on the abdominal aorta the patient was scheduled to undergo, prompted the authors to avulse the cutaneous lesion with tooth extraction, after a "Caldwell-Luc" operation of the homolateral paranasal sinus. Full restitutio ad integrum was achieved.
