Primary ovarian trabecular carcinoid tumor: a case report and literature review

INTRODUCTION: Carcinoid tumors are uncommon neoplasms in the diffuse peripheral endocrine system. Ovarian carcinoids are rare and can be primary or transplanted. Primary ovarian carcinoids make up approximately 0.5-1.7% of all carcinoid tumors.

.....The immunohistochemical study revealed a neuroendocrine origin with strong positivity for NSE, CgA and Syn. Other markers, such as a-inhibin and Calretinin, were negative. Finally, the case was diagnosed as a primary ovarian trabecular carcinoid tumor.

CONCLUSION: Primary ovarian trabecular carcinoid tumors are very rare. The patients lack clinical indicators, and final diagnosis depends on pathological examination, special staining and inmmunohistochemistry staining to confirm the neuroendocrine differentiation.
