[Trigeminal neuralgia. First manifestation of adenocarcinoma of the prostate]. / Neuralgia del trigémino. Primera manifestación de un adenocarcinoma de próstata.

ABSTRACT

We report a case of adenocarcinoma of the prostate that had been incidentally discovered during patient evaluation for trigeminal nerve neuralgia refractory to treatment. Analysis revealed the underlying cause of neuralgia was tumor metastasis to the mandible, which had caused irritation of the fifth nerve. The patient was treated with complete androgenic block and his symptoms improved simultaneously with partial remission of metastasis.
