Papillary thyroid carcinoma is the most common thyroid malignancy worldwide. The influence of clinicopathologic features on prognosis has been examined, but the relationship between cytologic features obtained by fine-needle aspiration (FNA) and prognosis has been minimally studied. We retrospectively studied the cytologic features with computerized morphometry in 83 patients with usual-type papillary thyroid cancer and followed them for more than 10 years except for one with metastasis at diagnosis. The cytologic features of FNA and recurrence of cancer were examined statistically.

Thyroid nodules are common (prevalence of 12.7% in women), but are malignant in only 5% of cases. International experts agree that a preliminary cytological examination by fine needle aspi...
The purpose of this study is to evaluate how common gene mutations are in benign and malignant thyroid lesions.
Thyroid nodules are a very common clinical problem with prevalence of up to 68% in adults on high-resolution ultrasound .Ultrasound used in order to differentiate between benign and malign...
A clinical trial is proposed, to clinically validate, in a US population, the diagnostic performance of a new genetic test (ThyroidPrint). It will determine the nature of thyroid nodules t...
To evaluate the application value of contrast-enhanced ultrasound in the diagnosis of thyroid nodules using fine needle aspiration.
Thyroid fine-needle aspiration cytology (FNAC) is one of the most performed medical procedures worldwide. It is used as a diagnostic test to separate benign thyroid nodules (colloidal and hyperplastic...
Fine needle aspiration (FNA) is routinely used in triaging thyroid lesions in adults. However, role of FNA in pediatric thyroid lesions is less studied.
Thyroid nodules are very common, and their frequency is four to five times higher in women than in men. Most of them are benign, with only a very little percentage revealing a malignant neoplasm. Abou...
Hyalinizing trabecular tumor (HTT) is a rare thyroid tumor with low to minimal malignant potential. HTT is often misinterpreted as other thyroid tumors, including papillary thyroid carcinoma (PTC) and...
Many attribute the rise in incidence of thyroid cancer to a deluge of radiologically identified incidental thyroid nodules. The clinical implications are unclear.
Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.
An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.
Tumors or cancer of the THYROID GLAND.
Autoantibodies that bind to the thyroid-stimulating hormone (TSH) receptor (RECEPTORS, THYROTROPIN) on thyroid epithelial cells. The autoantibodies mimic TSH causing an unregulated production of thyroid hormones characteristic of GRAVES DISEASE.
A paired box transcription factor that functions in the development of THYROCYTES and the control of thyroid-specific gene expression. Mutations in the PAX8 gene are associated with THYROID DYSGENESIS and THYROID NEOPLASMS.
A diagnostic test is any kind of medical test performed to aid in the diagnosis or detection of disease. For example: to diagnose diseases to measure the progress or recovery from disease to confirm that a person is free from disease Clin...
The thyroid is a butterfly-shaped gland in the neck, just above thecollarbone and is an endocrine gland that make hormones. These Thyroid hormones control the rate of many activities in the body, including how fast the body burns calories and how fast th...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
