title: A draining sinus tract of obscure etiology: a case report.
abstract: A patient presented with a draining sinus tract on the lingual alveolus of the posterior mandibular ridge. The source of the sinus tract was not readily apparent. Radiographs created the impression that a lesion of unusual and possibly metastatic origin might be involved. Comprehensive diagnostic tests were ordered, but the source of the lesion remained obscure until a surgical exploration was performed.
