CGA and carcinoma: In our case, pre-operative biopsy showed both neuroendocrine (Syn and CgA) and carcinoma (panCK+) markers, but the cyto/histology were predominant of NET, and there was no ground (<30% carcinoma component) for a formal MiNEN diagnosis, and we could prove a diagnosis of adeno-MiNEN only at the post-operative histological examination.
