頸動脈小体腫瘍の 1 例

抄録

A woman aged in her 50’s was incidentally diagnosed as having a carotid body tumor, which was then completely excised.

The cytological findings showed tumor cells arranged singly and in small clusters, with abundant or granular cytoplasm. The nuclei were round, with granular chromatin and small nucleoli. Histopathological examination of the resected tumor specimen revealed the characteristic Zellballen pattern, and immunohistochemistry revealed a diffusely positive reaction in the cytoplasm for neuroendocrine markers. Based on the findings, we diagnosed the tumor as a paraganglioma arising from the carotid body.

We report this relatively rare case here and consider that the diagnosis of this tumor could be confirmed or supported by the characteristic cytological findings.
