Objective:
The aim of this case report is to discuss the clinicopathological features of a patient with a primary renal carcinoid tumor.
Methods:
We report on the clinical and pathological information of one case of a patient with a primary renal carcinoid tumor as well as review relative literature.
Results:
The patient was diagnosed with a renal tumor when she received physical examination, and exhibited no positive symptoms. The diameter of tumor was 5 cm, the cross surface of the tumor was light yellow and firm, and the central part was soft with hemorrhage and necrosis. Immunohistochemical staining revealed strong and diffuse staining with synaptophysin, chromogranin A, and neuron-specific enolase.
Conclusion:
A primary renal carcinoid tumor is extremely rare. Surgical resection is a preferred therapeutic method.
