Ultrastructural Morphometry of Thyroid Neoplasms
American Journal of Clinical Pathology, 1983This paper presents the first comprehensive morphometry analysis of normal thyroid, adenomas, and follicular and papillary carcinomas. The mean nuclear volume and the mean nuclear surface increased, while the volume densities of rough endoplasmic reticulum and dense bodies decreased from normal thyroid through adenomas and follicular carcinomas to ...

Hürthle Cell Neoplasms of the Thyroid
Otolaryngologic Clinics of North America, 1990The approach to Hürthle cell neoplasms of the thyroid gland remains controversial because there is no consensus on the criteria used to establish malignancy. Invasion into the thyroid capsule, blood vessels, and contiguous structures in the neck and lymph nodes, or distant metastases establishes malignancy. Benign Hürthle cell lesions should be treated

Oncocytic Neoplasms of the Thyroid Gland
Acta Pathologica Japonica, 1992Among well differentiated thyroid tumors, oncocytic neo plasms feature a distinctive set of clinical, morphologic and biologic characteristics, some of which have been a matter of controversy. The world literature on this subject has been reviewed to show that: 1) Morphology accurately predicts the behavior of Hurthie cell tumors assuming that the ...

Hurthle Cell Neoplasms of the Thyroid
The Laryngoscope, 2002AbstractObjectives/Hypothesis Hurthle cell tumors are a variant of follicular cell neoplasms. The purpose of the study was to determine the reliability of intraoperative frozen‐section analysis for diagnosing Hurthle cell carcinoma and Hurthle cell neoplasm and to evaluate age, gender, and tumor size differences in the incidence of Hurthle cell ...

Unilateral thyroid neoplasm in a cat
Veterinary Record, 1980An aged cat with a thyroid neoplasm showed clinical signs and had laboratory data and post mortem findings similar to those observed in human and canine patients afflicted with hyperthyroidism. Because of these similarities hyperthyroidism was suspected in the cat.

Molecular Pathobiology of Thyroid Neoplasms
Endocrine Pathology, 2002Tumors of thyroid follicular cells provide a very interesting model to understand the development of human cancer. It is becoming apparent that distinct molecular events are associated with specific stages in a multistep tumorigenic process with good genotype/ phenotype correlation.

Molecular biology of thyroid neoplasms.
Rays, 2000Thyroid tumorigenesis proceeds through the progressive accumulation of alterations in genes involved in the regulation of cell proliferation and differentiation accompanying the acquisition of phenotypic, biological and clinical characteristics of increasing malignancy and dedifferentiation.

[Thyroid activity in patients with thyroid neoplasms].
Voprosy onkologii, 1984Levels of thyroid hormones and thyrotropin in 58 cases of adenoma and 86 cases of cancer of the thyroid gland were assayed radioimmunologically. Secretory function of the thyroid gland was inhibited in cancer patients and increased in adenoma group. Due to feedback, peripheral blood--thyrotropin levels were lowered in adenoma patients and raised in the
