GRANULOMATOUS THYMITIS ASSOCIATED WITH CH RONIC POLYRADICULITIS

We report on a 48-year-old man who developed over several months a pro gressive polyradiculitis. An extensive space-occupying lesion in the a nterior mediastinum was diagnosed and a thymoma was suspected. Histolo gical examination, however, did not reveal neoplasia but granulomatous thymitis. Thymectomy and corticoid therapy led to clinical normalizat ion. The association of thymitis with chronic polyradiculitis has not been previously described. The possible origins of this combination ar e discussed.
