Click, atypia of undetermined significance / follicular lesion of undetermined significance, solid cell nests / ultimobranchial body remnants, sclerosing mucoepidermoid carcinoma with eosinophilia. Background: Poorly differentiated thyroid cancer (PDTC) is a rare but clinically highly significant entity because it accounts for most fatalities from non-anaplastic follicular cell-derived thyroid cancer. The term poorly differentiated thyroid carcinoma (PDTC) was first proposed in the 1980s, but it was not definitively recognized as a distinct pathologic entity until the most recent classification of endocrine tumors by the World Health Organization in 2004. Methods and results. Poorly differentiated thyroid carcinomas (PDTC) in young individuals are rare and their clinical and histopathologic features, genetic mechanisms, and outcomes remain largely unknown. Poorly differentiated carcinoma (PDC) was defined with Turin consensus criteria more precisely for its histopathological diagnosis, and PTC with solid growth without increased mitosis and/or tumor necrosis were removed from PDC and was placed in PTC as an aggressive variant (solid variant of PTC).

Poorly differentiated thyroid carcinoma (PDTC) is a rare neoplasm with an aggressiveness midway between that of differentiated (follicular and papillary carcinomas) and undifferentiated carcinomas [ 1 ]. Poorly differentiated thyroid carcinomas (PDTC) in young individuals are rare and their clinical and histopathologic features, genetic mechanisms, and … The term poorly differentiated (PD) carcinoma was proposed 20 years ago to define aggressive, follicular‐derived thyroid carcinomas with behavior intermediate between follicular/papillary and anaplastic carcinomas. and D.L.C.) This website is intended for pathologists and laboratory personnel but not for patients. More than 95% of thyroid malignant tumors are derived from thyroid follicular epithelium, which includes PTC, follicular thyroid cancer (FTC), poorly differentiated thyroid cancer (PDTC), and undifferentiated or anaplastic thyroid cancer (ATC), among them, PTC accounts for about 85% [12] [13].

Conversely, some authors pointed out … Background: Please enable it to take advantage of the complete set of features! The term Poorly Differentiated Thyroid Carcinoma (PDTC) was first proposed in the early eighties to describe a heterogeneous group of neoplasms, of follicular cell origin, dwelling in an intermediate clinicopathological position between well-differentiated follicular or papillary carcinomas and undifferentiated carcinomas. Archived histopathology slides of 69 patients were available for review by two independent pathologists (R.G. These three thyroid carcinomas were large; the tumors from patients 1 and 3 were encapsulated, and that from patient 2 showed invasive growth. Due to the relative rarity of the disease and heterogeneous diagnostic criteria, studies on PDTC have been limited. Genetics of Familial Non-Medullary Thyroid Carcinoma (FNMTC). Some PDTCs arise from pre-existing, well-differentiated carcinomas of follicular cell origin; however, others most likely arise de novo [ 2 ]. The differences of survival rates among well differentiated, poorly differentiated and anaplastic carcinomas were statistically significant. See this image and copyright information in PMC. Poorly differentiated carcinoma was found in 13.6% of all thyroid malignancies, and its prognosis was worse than that of well differentiated carcinoma. Epub 2017 Jun 20. Poor prognostic factors in papillary carcinoma include older age at diagnosis, male sex, large tumor size, and extrathyroidal growth. There was a median of 21 slides per specimen. 25% PDTC were PDL1 positive. In light of the evolution of ultra-deep next-generation sequencing technologies and through correlation of clinicopathologic and genomic characteristics of PDTC, an improved understanding of the biology of PDTC has been facilitated. To characterise the mutational profiles of poorly differentiated thyroid carcinoma (PDTC) and anaplastic thyroid carcinoma (ATC) and to identify markers with potential diagnostic, prognostic and therapeutic significance. Poorly differentiated thyroid cancer (PDTC) has remained a controversial diagnosis. Xu W, Li C, Ma B, Lu Z, Wang Y, Jiang H, Luo Y, Yang Y, Wang X, Liao T, Ji Q, Wang Y, Wei W. Front Oncol. Although the morphologic criteria for PD tumors are well defined, it is not clear how much of a PD area besides a well-differentiated component in a given tumor is required to allow such a diagnosis.
