Tic douloureux as a presenting feature of facial leprosy: diagnostic enigma in Taiwan.

PURPOSE: Leprosy is rarely seen in Taiwan. We herein report a foreign worker concomitantly with facial borderline tuberculoid leprosy presenting with trigeminal neuralgia.

CASE REPORT: A 26-year-old male foreign labor from Indonesia, presented with 1 year history of a hypoanaesthetic erythematous plaque of right face and subsequent 6 months constant, severe pain in the right side of his face over the nasolabial groove. Biopsies and histopathological examination confirmed the diagnosis of leprosy. We treated the patient with a multidrug regimen including dapsone, clofazimine, and rifampine since April of 2012 with a good response.

CONCLUSIONS

We report a rare case of new-onset leprosy presenting with trigeminal neuralgia in Taiwan and suggest leprosy should be listed in the differential diagnosis of unusual skin manifestations and neuralgia.
