1/741. Malignant struma ovarii.A rare case of malignant struma ovarii is presented. The tumor was excised together with the ovary and interpreted as a papillary strumal adenocarcinoma arising in a cystic teratoma with predominant thyroid elements. Prior to surgery the patient did not show any symptoms of thyroid hyperfunction. The thyroid function tests performed subsequent to surgery were within normal limits. Periodic examinations of the patient over a period of three years did not reveal any abnormalities. Statistically, this type of malignancy carries a good prognosis with a high "cure" rate.- - - - - - - - - - ranking = 1keywords = thyroid (Clic here for more details about this article) |
2/741. thyroid gland papillary carcinoma with fibromatosis-like stroma: case report.Papillary carcinoma of the thyroid may show a variable degree of fibrosis of the stroma, but proliferation of the stromal fibroblasts mimicking fibromatosis is rare. There appears to be a new variant of papillary carcinoma of the thyroid associated with exuberant proliferation of the fibroblasts resembling fibromatosis. We present one such case in a 50 year old woman and succinctly reviewed the relevant literature of this rare variant. The necessity of a diligent search for a papillary carcinoma in thyroid gland which shows a proliferative fibrous lesion is stressed.- - - - - - - - - - ranking = 1keywords = thyroid (Clic here for more details about this article) |
3/741. False-positive result of a total-body scan caused by benign thyroidal tissue after I-131 ablation.This case report illustrates a false-positive result of an I-131 total-body scan caused by abnormal, noncancerous thyroid tissue. A 39-year-old woman underwent an open biopsy and thyroidectomy for a papillary thyroid carcinoma. She was treated by ablation with 150.8 mCi I-131. A follow-up total-body scan revealed a solitary focus of increased activity near the midline at the upper border of the larynx that was subsequently excised. Histologic analysis indicated a fragment of thyroid tissue with chronic inflammation, fibrosis, and squamous metaplasia. No evidence of thyroid carcinoma was present. Hypofunctioning or nonfunctioning residual tissue within the thyroglossal duct may have been suppressed under euthyroid conditions, protecting it from ablation. This tissue may have become stimulated by the high thyroid-stimulating hormone levels, accumulating I-131 and producing a false-positive result of the scan.- - - - - - - - - - ranking = 3.6666666666667keywords = thyroid (Clic here for more details about this article) |
4/741. Tall cell variant of papillary thyroid carcinoma with foci of columnar cell component.We report a case of the tall call variant of papillary thyroid carcinoma with foci of columnar cell component in a 67-year-old Japanese man. Tall cell variant occupied more than 70% of the tumour, and columnar cell component was of two types in representative sections. One showed striking stratification of nuclei with scanty cytoplasm, and the other appeared clear. Characteristic nuclear features of papillary carcinoma were also observed in the area of the tall cell variant. The patient died of the thyroid cancer with aspiration pneumonia 10 years and 6 months after operation. Although autopsy was not performed, metastatic lymph nodes of the neck removed during life also showed papillary carcinoma with both tall cell and columnar cell components. Our case indicates that tall cell and columnar cell variants may coexist in the same tumour although the pathogenesis remains unclear.- - - - - - - - - - ranking = 2keywords = thyroid (Clic here for more details about this article) |
5/741. Tall cell variant of papillary thyroid cancer.Papillary histologic type is the most common form of thyroid carcinoma amounting to 85% cases. This pathology presents a rather good prognosis, but a few years ago, new subtypes have been described. Some of these variants show a fairly good prognosis i.e follicular, macropapillary, encapsulated while others appear to have a decidedly worse one, columnar cells, diffused sclerosing, or even to be clearly malignant as in the case of the tall cell variant. The authors report a case treated by a combined surgical and radiometabolic therapy and evidence the main characteristics of this rare and underestimated neoplasia.- - - - - - - - - - ranking = 1.6666666666667keywords = thyroid (Clic here for more details about this article) |
6/741. Thyroid autonomy (Plummer's disease) with contralateral malignancy--mere coincidence?A patient with an autonomously functioning nodule in the left lobe and a papillary carcinoma in the right lobe of the thyroid gland is described.

8/741. Successful surgical treatment of a solitary parapharyngeal metastasis from thyroid cancer, using the mandibular swing-transcervical approach: report of a case.A 72-year-old man presented with a right parapharyngeal mass, 4 cm in diameter, which was subsequently diagnosed as a metastasis originating from papillary carcinoma of the thyroid gland. The parapharyngeal tumor was successfully removed by the mandibular swing-transcervical approach with pharyngeal reconstruction, performed using a buccal mucosal island flap based on the facial artery. His postoperative course was uneventful, and the preoperative clinical symptoms such as dysphagia and headaches completely resolved after surgery.- - - - - - - - - - ranking = 1.6666666666667keywords = thyroid (Clic here for more details about this article) |
9/741. Thyroid lung metastasis diagnosed 47 years after thyroidectomy.A 75-year-old woman underwent excision of a middle lobe lung nodule that contained a separate, isolated focus of metastatic papillary thyroid carcinoma. A thyroid lobectomy for papillary cancer had been performed 47 years earlier. This interval is believed to be the longest time from initial diagnosis to identification of distant lung metastasis reported. The pertinent published reports are reviewed and methods of surveillance discussed.- - - - - - - - - - ranking = 2.0010256455433keywords = thyroid, nodule (Clic here for more details about this article) |
10/741. Mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid: report of a case.The patient was 59-year-old Japanese woman who presented with a neck swelling. ultrasonography and computed tomography demonstrated a round tumor in the thyroid right lobe measuring 2.5 x 1.5 cm in size. A right hemithyroidectomy with lymph node dissection was performed. Histopathological findings demonstrated low-grade B cell lymphoma of the mucosa-associated lymphoid tissue (MALT) associated papillary microcarcinoma. A previous report showed an excellent prognosis of MALT lymphoma of the thyroid without capsular invasion or lymph node involvement. We also describe the concept of MALT lymphoma as a primary lesion in which lymphoid tissue is not present in the normal state.- - - - - - - - - - ranking = 2.3333333333333keywords = thyroid (Clic here for more details about this article) |
