We describe a 39-year-old woman presenting with a painless solitary thyroid nodule, initially without signs suggesting thyroiditis. The serum level of thyrotropin was suppressed whereas those of thyroxine and triiodothyronine were normal. Fine needle aspiration cytology showed no signs of inflammation or malignancy. One week later, the patient felt pain and tenderness on her neck, and erythrocy...

Accepted 23 April 1998 Summary We describe a 39-year-old woman presenting with a painless solitary thyroid nodule, initially without signs suggesting thyroiditis. The serum level ofthyrotropin was suppressed whereas those of thyroxine and triiodothyronine were normal. Fine needle aspiration cytology showed no signs ofinflammation or malignancy. One week later, the patient felt pain and tenderne...

BACKGROUND The role of serum TSH concentrations as a predictor of malignancy of thyroid nodule remains unclear. OBJECTIVE To prospectively evaluate the usefulness of serum TSH levels as a predictor of malignancy in thyroid nodules. METHODS Patients with thyroid nodule(s) who underwent fine-needle aspiration biopsy under ultrasonographic guidance in a tertiary, university-based hospital were...

Endobronchial metastasis is a rare manifestation of differentiated thyroid cancer. A 79-year-old male was admitted to the hospital with shortness of breath, chest pain, anemia, and weight loss. Computed tomography of chest revealed multiple lung nodules. Bronchoscopy showed an endobronchial lesion in the right upper lobe. The biopsy of the lesion demonstrated neoplastic cells stained positive f...

Although there is considerable controversy about the proper management of the solitary nodule, certain information may be useful in reaching this decision. Age, sex, and a previous history of external irradiation to the head and neck are helpful as are the clinical characteristics of the thyroid gland. Whether the nodule is functioning or "cold" on thyroid scan, and cystic or solid on thyroid u...

A case of follicular thyroid cancer with intense focal Methionine uptake on 11C-Methionine PET/CT is reported here. The use of 11C-Methionine PET in differentiated thyroid cancer is currently being investigated as a surrogate tracer compared to the more widely used 18F-FDG PET. This case illustrates the potential incremental value of this modality, not only in the localizing of parathyroid aden...

Secondary neoplasm of the thyroid mimicking a primary thyroid lesion is a rare finding, especially in an individual without a past history of malignancy. A case of squamous cell carcinoma metastatic to the thyroid (presenting as a solitary thyroid nodule), who had an unsuspected primary in the esophagus is described. Usually, multiple areas of the gland are involved in the secondary involvement...
