[Granular-cell tumor: review of the literature apropos of a case of bronchial site].

Abrikossoff's tumor, also called granular cell tumor, is an uncommon condition, generally benign, which can affect every organ and specially skin and tongue. The authors report an observation of a bronchial tumor and review the literature. Possible relapse after treatment, locally or everywhere in the body, may occur as local or regional complication that may necessit heavy surgery. It appears that a benign tumor can have macroscopic and even microscopic aspect of malignancy, when real malignant tumors are extremely rare. Wide excision still remain current treatment of Abrikossoff's tumor. Endoscopic methods are an interessant and less invasive alternative to treat some deep tumors.
