A case of granular cell tumour in the pituitary stalk is described marked by the sudden loss of visual acuity in the left eye, followed by the right years later. A comparison with 17 cases previously published and with cases of asymptomatic granular cell nodules leads the authors to suggest the term granular cell pituicytoma. They discuss the place of this neoformation among other systemic granular cell tumours (granular cell myoblastoma). Fifteen patients were operated on, complete excision being carried out in only three (including the case published). Whether complementary cobalt therapy is useful remains problematical since very few cases have been published because of the slow development of the neoplasm.
