FOLLICULAR NEOPLASM, RIGHT LOBE THYROID WITH RETROSTERNAL EXTENSION- CASE REPORT

Sreevidya S.* and Bismi S.

ABSTRACT

Follicular neoplasm (consisting of the combination of high numbers of follicular cells, micro follicular arrangement, and scant or absent colloid) is a cytologic term used to encompass both the benign proliferation of thyroid follicular cells in adenoma and the malignant proliferation in carcinoma. Follicular adenomas are much more common than follicular carcinomas, occupying a histologic niche between follicular hyperplasia and follicular carcinoma. Retrosternal goiter is defined when 50% of the thyroid is below the thoracic inlet. This can also be called as intra thoracic goiter. Retrosternal goiter is a very rare condition which account for 5 to 20% of thyroidectomy patients.1 Mediastinal extension is more common in huge goiters with a peak incidence in 5th to 6th decade. This is usually rare when the patient has associated hyperthyroidism which may increase the risk of complications. The reported incidence of goiters with thyroid malignancy is around 3 to 17%.1,2 Retrosternal goitre occurs when the thyroid enlarges downwards into the chest. Although the great majority of retrosternal goitres are extensions from the neck, pure intra thoracic goitres are very rare. Here we present an unusual way in which a 51 year old male was found to have Follicular Neoplasm, Right Lobe Thyroid With Retrosternal Extension.
