갑상선 여포종양의 임상적 특성 및 감별진단

Abstract

Background and Objectives：A preoperative diferential diagnosis betwen follicular adenoma and follicular carcinoma of thyroid is very dificult, and the standard basis for distinction is the presence of capsular and/or vascular invasion. In this study, the folli-cular neoplasm. Subjects and Method：A retrospective review of medical records was caried out on 104 patients who had undergone thyroid surgery and had been diagnosed with thyroid follicular adenoma or carcinoma from 195 through 204. The final pathologic diagnosis was compared to the various clinical data including the result of fine needle aspiration cytology (FNAC) and ultrasonographic findings. Results：Of total 104 cases, 82 were follicular adenoma and 22 were follicular carcinoma. The incidence of carcinoma was significantly higher in male than in female. The result of FNAC were divided into 6 cyto-diagnostic groups, namely, inadequate, colloid nodule without atypia, colloid nodule with atypia, follicular neoplasm without atypia, folicular neoplasm with atypia, or highly suspicious malignancy. The incidence of carcinoma was significantly higher in the groups with atypia such as colloid nodule with atypia, follicular neoplasm with atypia, and highly suspicious malignancy than ci-fication on ultrasonography also indicated the posibility of malignancy. Conclusion：The incidence of follicular carcinoma was significantly high in male patients, atypia in FNAC, and ill-defined margin and calcification on ultrasonography.
