Cutaneous sinus tract from remaining tooth fragment of edentulous maxilla.

Cutaneous sinus tract of dental origin usually arises from chronic dental infections. These tracts usually appear as suppurative lesions of the chin or neck. Because many patients with this lesion do not have any complaints of oral symptoms, these lesions are often diagnosed incorrectly and overlooked, and are also treated ineffectively. A case of an unusual presentation of a chronic suppurative granuloma on nasolabial fold, which originated from the remaining tooth fragment of edentulous maxilla, is reported. Treatment with removal of the tooth fragment as well as the sinus tract resulted in complete healing of the lesion. This report emphasizes the importance of awareness of the possible dental origin of facial sinuses, despite their unusual location.
