| Abstract: | A case of gangliocytic paraganglioma of the duodenum is reported, including light microscopic, ultrastructural, and immunohistochemical characteristics. The cytologic appearance, as might be seen in fine-needle aspiration smears, indicates a neoplasm with three cellular components (epithelioid, ganglion, and spindle cells) seen histologically by light and electron microscopy. |
