four patients are described in whom a follicular carcinoma developed following thyroidectomy for a benign follicular neoplasm. it is possible that the initial thyroid neoplasm was a well- differentiated follicular carcinoma which was microscopically indistinguishable from a benign adenoma. realizing this pathologic pitfall in thyroid diagnosis, the need for meticulous examination of the patholo...

INTRODUCTION Papillary thyroid carcinoma and medullary thyroid carcinoma are two different thyroid neoplasia. The simultaneous occurrence of medullary thyroid carcinoma and papillary thyroid carcinoma as a collison tumor with metastases from both lesions in the regional lymph nodes is a rare phenomenon. CASE PRESENTATION A 32-year-old Iranian man presented with a fixed anterior neck mass. Ult...

Thyroid cancer is the most common endocrine malignancy. This study surveys the pathologic characteristics of thyroid cancerin Mashhad and study of papillary carcinoma in more detail. In this retrospective study, 108 out of 197 cases of thyroid cancer were papillary in type (55%), with female to male ratio of 1.91 which is lower than current reports. The age at the time of diagnosis ranged ...

Background: Thyroid carcinoma is the most common malignancy of the endocrine system. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. Thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. As a result of diagnostic methods improvement, p...

Renal tumor metastasis from thyroid follicular carcinoma is very rare. Here, we present a 64-year-old woman with metastatic thyroid follicular carcinoma presenting as a primary renal tumor. The renal tumor was removed and revealed the origin of thyroid follicular carcinoma. Six months after the treatment of renal tumor, the patient was readmitted for the enlarged thyroid gland. The follicular c...

Introduction apillary carcinoma of thyroid is a common thyroid malignancy and most common endocrine neoplasia in those countries where iodine is sufficient or excess in their diet. Female are affected more commonly than male. Mean age of initial diagnosis of papillary carcinoma is 40 years. In case of children 90% of thyroid malignancy is papillary carcinoma. Papillary carcinoma of thyroid has ...

Thyroid cancer accounts for approximately 1% of all human cancers. Follicular carcinoma thyroid (FCT) is the second most common thyroid cancer after papillary carcinoma. Follicular carcinoma thyroid accounts for 10-15% of clinically evident thyroid malignancies. Follicular carcinoma thyroid commonly metastasize to lung and bone. Intracranial metastasis occurs in about only 1%. Follicular carcin...

Thyroid cancer is the most common malignancy in endocrine system, composed of four major types; papillary thyroid carcinoma, follicular thyroid carcinoma, anaplastic thyroid carcinoma, and medullary thyroid carcinoma. The incidence of thyroid cancer, especially differentiated thyroid cancer, is increasing in developed countries. Growing body of studies on molecular pathogenesis in thyroid cance...

Thyroid follicular epithelial cell–derived cancer includes papillary carcinoma, Hürthle cell poorly differentiated thyroid cancer, and anaplastic carcinoma. Although the incidence of has increased over past 30 years, there not been a significant increase in patient mortality. Use increasingly sensitive detection methods such as high-resolution imaging enabled earlier better characterization mal...
