BACKGROUND Sensitivity and specificity data regarding positron emission tomography (PET) and PET/CT for surveillance of well-differentiated thyroid cancer does not evaluate subtypes separately. Papillary and follicular thyroid carcinoma may have different characteristics on PET/CT imaging and so should be investigated individually. METHODS This is a systematic meta-analysis of studies using P...

Backround. Thyroglossal duct cyst (TDC) is a developmental abnormality of the thyroid gland. Due to embryological remnants of thyroid tissue located in the TDC, the same malignant tumors that develop in the thyroid gland can also develop in the TDC. Methods. We present the unique case of a 39-year-old female with simultaneous de novo papillary carcinoma in a TDC and the thyroid gland. Results. ...

With fewer than 40 cases described in the otolaryngology literature, mixed medullary papillary thyroid carcinoma represents a rare but phenotypically distinct tumor. While isolated medullary carcinoma may be admixed with normal follicular structures, true mixed carcinoma displays morphological and immunological characteristics of medullary and papillary carcinoma within a single lesion. We repo...

INTRODUCTION The link between Hashimoto's thyroiditis and thyroid carcinoma has long been a topic of controversy. OBJECTIVE The aim of our study was to determine the prevalence of thyroid carcinoma and Hashimoto's thyroiditis coexistence in histopathologic material of thyroidectomized patients. METHODS In a retrospective study, the clinicohistopathologic data of 2117 patients (1738 females/...

BACKGROUND Papillary carcinoma is the most common differentiated malignant thyroid neoplasm. The biological course of this cancer is typically indolent with a protracted clinical course. Metastases commonly occur in regional lymph nodes, and distant metastasis is a late and rare occurrence. We report a patient who presented with cerebellar metastasis prior to the diagnosis of papillary thyroid ...

we studied the clinical, radioisotopic, and pathologic characteristics and the incidence of cancer in clinically solitary cold nodules of the thyroid in an iodinedeficient area. the study included retrospective analysis of 765 patients who underwent thyroidectomy for a clinically single cold nodule in a ten-year period. we compared the pathological findings with clinical data. in pathological e...

The salient features of 15 cases of carcinoma of the thyroid and phaeochromocytoma taken from the literature and two personal cases are reviewed. The significant points noted are the frequency with which the adrenal tumours were bilateral, the frequency with which a family history of phaeochromocytoma (six cases) and thyroid carcinoma (four cases) was present, and the frequency with which the t...

BACKGROUND Thyroid carcinoma occurring as a second primary associated with head and neck squamous cell carcinoma (HNSCC) is unusual. The clinical management of thyroid cancer in such cases has been debated. METHODS Between 1975 and 2004, we collected 33 cases. The associated thyroid carcinoma was diagnosed either during or as a consequence of surgery planned as head and neck cancer treatment....

We present a 73-year-old female with advanced thyroid papillary carcinoma who complained of gross hematuria. We found a bladder tumor and considered it the cause of her symptom. Cystoscopic findings of the tumor were unusual, with peri-tumor vessel formation. Pathological examination of the bladder tumor was consistent with metastasis of thyroid papillary carcinoma. Therefore, we identified thy...

Warthin tumor-like papillary thyroid carcinoma is an uncommon variant of papillary thyroid carcinoma. We report a rare case of Warthin tumor-like variant of papillary thyroid carcinoma with a dedifferentiated component consisting of a solid tumor area composed of neoplastic cells with a spindle to tall cell morphology associated with marked nuclear pleomorphism, atypical mitoses, and foci of ne...
