introduction struma ovarii is an ovarian teratoma, represented in more than 50% by thyroid tissue. five percent of struma ovarii cases have been proven to be malignant and, as in the thyroid gland, papillary thyroid carcinoma is the most common histotype arising in struma ovarii. because of the unusual occurrence of this tumor, its management and follow-up after pelvic surgery is still controve...
OBJECTIVE It is uncommon for dermatomyositis to be associated with papillary thyroid cancer. We report an unusual case of papillary thyroid cancer presenting with dermatomyositis. METHODS The case history, imaging and laboratory data is reviewed. RESULTS We report the case of a 62-year-old female with a prior history of dermatomyositis and breast cancer who presented with a recurrent episod...
BACKGROUND Struma testis is a rare entity, and there are only few reports on the malignant transformation of a testicular teratoma to papillary thyroid carcinoma in the literature. In this report, we describe the malignant transformation of struma testis with distant lung metastasis associated with trisomy 17 and a coexisting papillary microcarcinoma in the thyroid. CASE REPORT A 56-year-old ...
A major early event in papillary thyroid carcinogenesis is constitutive activation of the mitogen-activated protein kinase signaling pathway caused by alterations of a single gene, typically rearrangements of the RET and NTRK1 genes or point mutations in the BRAF and RAS genes. In childhood papillary thyroid cancer, regardless of history of radiation exposure, RET/PTC rearrangements are a major...
The question is complicated, as there are different types of thyroid cancer, and a causal relationship is hard to prove. Glucagon-like peptide 1 (GLP-1) receptor agonists can be safely used in all patients with thyroid cancers that are derived from the thyroid follicular epithelium (papillary and follicular thyroid cancer). However, they are currently contraindicated in patients with medullary ...
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...
Background: Warthin tumor- like papillary carcinoma of thyroid is a rare variant of papillary thyroid carcinoma. It is characterized by distinct papillary structures lined by oncocytic tumor cells with nuclear features of papillary carcinoma and marked lymphoplasmocytic infiltrate in the papillary stalks. This tumor derives its name from its resemblance to Warthin tumor of major salivary glands...
abstract introduction: cancer stem cells are a small subpopulation of cells within a tumor which are responsible for maintaining the tumor mass. a number of factors such as oct-4 that govern the fate of adult stem cells also play a role in malignant cell transformation. oct-4 is a key regulator of self-renewal in embryonic stem cells; its expression is potentially correlated with tumorigenesis ...
Thyroid hemiagenesis with or without isthmus is a rare congenital disorder. Papillary thyroid carcinoma associate with hemiagenesis is very rare. A 42 years old female with chief complain of cervical mass was referred to our center. In physical examination, she had a 1.5 × 1.5 nodule in right lobe of thyroid. The result of thyroid nodule fine needle aspiration was reported papillary thyroid c...
UNLABELLED The aim of the present study was to present data on frequency of thyroid cancer in Mures County (Romania) and border counties, a goiter endemic area, and to analyze its histopathological characteristics, over a 20 years period (1990-2009). MATERIALS AND METHODS Demographic, clinical and pathological data were obtained from database registries. Histological subtypes of thyroid cance...
