Preoperative diagnosis of follicular variant of papillary carcinoma of thyroid-A retrospective study

Follicular variant of papillary carcinoma is the second common variant of papillary carcinoma. The diagnosis of follicular variant pre-operatively has been really very challenging and the incidence of false diagnosis is also very high. So, an attempt has been made to study the cytological as well as ultrasound findings of histologically proven cases of follicular variant of papillary carcinoma of thyroid.

Sonographic findings and cytology findings of 20 histologically proven cases of Follicular variant of papillary carcinoma of thyroid are retrospectively reviewed.

Only 50% of cases were diagnosed as malignant on ultrasound and only 25% cases were diagnosed malignant on cytology.

The sensitivity of diagnosis is more radiologically, so all the thyroid FNAC should be done under ultrasound guidance and also nuclear features of Papillary carcinoma should be more carefully looked into in all suspicious cases. With these initiatives, the accuracy of cytological diagnosis of FVPTC can be substantially increased.
