Neuroendocrine tumours are a heterogeneous group of tumours originating in various anatomical locations. The management of this disease represents a significant challenge because of the heterogeneous clinical presentations and varying tumour biology. Oncocytic variant of neuroendocrine tumour is rare and the diagnosis is based on histopathological analysis following surgery. The lack of specific clinical features makes preoperative diagnosis difficult. We report two cases of oncocytic variant of neuroendocrine tumours and review of the literature of this subtype of neuroendocrine tumour.
