Symptomatic granular cell tumour of the pituitary.

Granular cell tumours (GCT) and pituicytomas are rare tumours seen in the sellar suprasellar region which are believed to arise from either the infundibulum or the posterior lobe of the pituitary gland. Whether they are two distinct lesions or represent one single pathological entity remains a matter of debate. We report the case of a 42-year-old male with a granular cell neoplasm of the sellar suprasellar region and attempt to discuss the controversies shrouding this distinct clinicopathological entity.
