Referred Orofacial Pain as an Initial Symptom of Distant, Nonmetastatic Cancer: Report of a Case and Review of the Literature.

Referred orofacial pain as the first symptom of an otherwise silent distant, nonmetastatic cancer has been reported, but there is sparse literature on the subject. Referred pain may not be considered in the orofacial pain differential diagnosis because of its rarity; however, this may delay a cancer diagnosis. The authors present a case report and a review of the English literature.
