Struma ovarii or monodermal teratoma, is a specialized ovarian neoplasm composed entirely of mature thyroid tissue. It is a relatively rare tumor which comprises 1% of all ovarian tumors and 2.7% of all dermoid tumors. Its colour and consistency is like that of a thyroid tissue. The tissue may show any of the pathologic changes seen in a normally placed gland, including diffuse or nodular hyper...

When Policy Topic is covered The use of the Afirma Gene Expression Classifier in fine needle aspirates of the thyroid that are cytologically considered to be indeterminate (follicular lesion of undetermined significance or follicular neoplasm) may be considered medically necessary in patients who have the following characteristics:  Thyroid nodules without strong clinical or radiologic finding...

Spindle epithelial tumor with thymus-like element (SETTLE) is a rare malignant neoplasm of the thyroid, occurring predominantly in children, adolescents, and young adults. SETTLE usually presents itself as a thyroid mass, without metastases at diagnosis. It is believed to derive from branchial pouch or thymic remnant tissue showing primitive thymic differentiation. This article reports the clin...

PSMA PET is increasingly being used in imaging of recurrent prostate carcinoma. A case with suspected recurrent Prostate carcinoma (PCa), raised PSA (Prostate specific antigen) and suspected spinal metastases was referred for whole body Ga-68-PSMA PET/MRI. The study revealed PSMA avid recurrent prostate mass and extensive osseous metastases. Abnormal PSMA uptake in the thyroid gland prompted US...

INTRODUCTION Thyroid carcinoma represents total 1 % of human neoplasm with increasing incidence for the last 4 decades. However, that increase appears to be due to an increase in the diagnosis of papillary microcarcinomas associated with increased sampling of 1 resected specimens by pathologists . Epidemiologically ascertained risk factors are ionising radiation, the presence of thyroid adenoma...

Background: Classical teaching dictates that follicular adenoma (FA) can be distinguished from follicular carcinoma (FC) based on histologic features only. We retrospectively reviewed our institution’s 10-year experience in the use of fine-needle aspiration (FNA) to diagnose follicular thyroid neoplasms. Methods: Patients who had FNA of a thyroid neoplasm from 2000 to 2010 were reviewed. Diagno...

CONTEXT Struma ovarii, a rare neoplasm, is a monophyletic teratoma composed of thyroid tissue. It is generally considered to account for less than 5% of mature teratomas. CASE REPORT A diagnosis of struma ovarii may be the source of many diagnostic problems. It may be cystic and microscopic examination may only reveal a few typical thyroid follicles, resulting in confusion with other cystic o...

BACKGROUND To date, appropriate management for Bethesda IV thyroid nodules is controversial, and no specific features of follicular neoplasm and nodular hyperplasia on ultrasonography, computed tomography (CT), or other imaging modalities have been reported. This study aimed to compare CT features of follicular neoplasm and nodular hyperplasia and to determine the specific CT features that coul...

Thyroid fine-needle aspiration (FNA) is a standard procedure for the clinical triage of thyroid nodules. The diagnosis of an adequately sampled thyroid FNA is generally grouped into three categories: benign, malignant, and indeterminate. The latter group usually includes follicular neoplasm, follicular lesion, and sometimes a more specific diagnosis such as Hurthle cell neoplasm or follicular l...
