Nuclear grooving; Pseudoinclusion; Thyroid; Papillary Background: Fine Needle Aspiration Cytology is a widely accepted diagnostic tool for thyroid lesions. It is well known that nuclear features form the mainstay of diagnosis for papillary carcinoma thyroid. Focal nuclear features can be missed unless carefully looked for and pose diagnostic difficulty. The aim was to study the cytomorphologica...

This is a case report on papillary thyroglossal duct cyst (TGDC) carcinoma along with synchronous occult papillary thyroid microcarcinoma. A 46-year-old woman visited our hospital because she had an anterior midline neck mass below her hyoid bone. Preoperative ultrasound-guided fine-needle aspiration cytology revealed signs of papillary TGDC carcinoma. We performed a Sistrunk operation and a to...

This was an extremely rare case of unusual granular cell tumor of the trachea coexisting with recurrent papillary thyroid carcinoma. We initially misdiagnosed this patient as having tracheal invasion from recurrent thyroid carcinoma even after a computed tomography scan and fine-needle aspiration cytology.Clinicians should be aware of the possibility of granular cell tumor of the trachea occurr...

Well-differentiated papillary and follicular thyroid carcinomas are the two most common types of thyroid cancer. Although cancerous cells in both types phenotypically resemble the epithelial follicular cell, the tumors display different histological characteristics and clinical outcomes. Molecular defects contributing to the separate development pathways remain largely unclear. We evaluated gen...

Thyroid cancer is one of the most frequently diagnosed cancers of the endocrine system. There are no known genetic risk factors for non-medullary thyroid cancer, other than a small number of hereditary syndromes; however, approximately 5% of non-medullary thyroid cancer, designated familial non-medullary thyroid cancer, exhibits heritability. The p.G534E (c.1601G>A) variant of HABP2 was recentl...

 Abstract Background: Thyroglossal duct cysts (TDC) are the most common congenital neck masses arising from the expansion of the epithelial tract remnants occurring during embryogenic thyroid migration. About 7% of the population have thyroglossal duct remnants. Clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. Thyroglossal duct cysts may r...

BACKGROUND Metastatic papillary thyroid carcinoma typically appears in local lymph nodes. Skin metastases are rare. PURPOSE A man with progressive metastatic papillary thyroid carcinoma who developed a cutaneous metastasis on his nose is described. The clinical manifestations of metastatic papillary thyroid carcinoma to skin are reviewed. METHODS PubMed was used to search the following term...

Dear Editor: I read with great interest the case report by Sun et al. (1), entitled "Papillary thyroid carcinoma treated with radiofrequency ablation in a patient with hypertrophic cardiomyopathy: a case report," which was published in the Korean Journal of Radiology (KJR), July 2016. The authors presented a subcentimetic papillary thyroid carcinoma treated by radiofrequency ablation in an inop...

We present a 73-year-old female with advanced thyroid papillary carcinoma who complained of gross hematuria. We found a bladder tumor and considered it the cause of her symptom. Cystoscopic findings of the tumor were unusual, with peri-tumor vessel formation. Pathological examination of the bladder tumor was consistent with metastasis of thyroid papillary carcinoma. Therefore, we identified thy...

Papillary carcinoma of thyroid is the most common type of thyroid neoplasm which is usually confined to the thyroid and tends to metastasize to regional lymph nodes. Distant metastasis occur in up to 15% of cases. Thymic metastasis from any malignant carcinoma is extremely rare with only four cases reported in medical literature. We report a case of papillary carcinoma of thyroid metastasizing ...
