1/223. 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 = gland (Clic here for more details about this article) |
2/223. 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. Some evidence suggests the association to be more than coincidental.- - - - - - - - - - ranking = 0.2keywords = gland (Clic here for more details about this article) |
3/223. 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 = 0.2keywords = gland (Clic here for more details about this article) |
4/223. carcinoma of the thyroid gland, adenoma of the adrenal cortex and peptic ulcer: an unreported association.A 39-year-old man, operated on for duodenal ulcer, was found to have a papillary carcinoma of the thyroid, an aldosterone-producing adenoma of the adrenal cortex, and a recurrence of a peptic ulcer. The probable coincidental occurrence of these diseases in this patient is suggested. Nevertheless, careful investigation of the other endocrine glands in patients with endocrine tumors is recommended.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
5/223. Intraductal papillary carcinoma of the parotid gland with low malignancy.A peculiar case of papillary carcinoma arising in the parotid gland is reported. A 68-year-old woman presented with a right, painless, parotid mass, measuring approximately 3 cm in greatest diameter. A conservative parotidectomy was performed. Histologically, the neoplasm showed exophytic papillary projections into a cavity. The cells were focally suggestive of epidermoidal differentiation, whereas a transitional differentiation was noted in other portions, as in bladder papilloma. Immunohistochemical studies showed strong positivity of the neoplastic cells for cytokeratin and weak positivity for PCNA and Mib-1. We classified this neoplasm among the papillary tumors with a low-grade of malignancy.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/223. Tall cell variant of papillary carcinoma coexisting with chronic lymphocytic thyroiditis. A case report.BACKGROUND: Recent studies have shown a correlation between lymphocytic thyroiditis and papillary carcinoma of the thyroid. It is thought that autoimmune thyroiditis could be a risk factor for the development of thyroid carcinoma, mainly for the papillary variant. CASE: A 59-year-old female presented with a history of enlargement in the neck and five months of dysphagia. Clinical examination showed generalized expansion and an increase in the hardness of the thyroid gland. Hormonal outline showed subclinical hypothyroidism with serum levels of TSH slightly elevated (5 micrograms/dL; range, 0.25-4). thyroglobulin antibodies and thyroperoxidase titers were moderately positive. Given these results, a diagnosis of chronic thyroiditis was made. Thyroid ultrasound scan showed diffuse gland irregularity and the presence of a solitary nodule (2.3 cm in diameter) localized in the right lobe. Fine needle aspiration biopsy (FNAB) of the nodule was performed under ultrasound guidance. CONCLUSION: Although clinical and laboratory results supported the diagnosis of autoimmune thyroiditis only, FNAB of the nodular lesion provided evidence of a rare case of papillary carcinoma, tall cell variant, confirmed by histologic results.- - - - - - - - - - ranking = 0.4keywords = gland (Clic here for more details about this article) |
7/223. Metastatic thyroid carcinoma of the mandibule.A case of metastatic papillary carcinoma to the mandible is presented. Though relatively rare, metastatic tumours of the mandible should be included in the differential diagnosis of the tumours in the parotid region. For the primary site; being in the cervicofacial region, the thyroid gland must be considered by the head and neck surgeon.- - - - - - - - - - ranking = 0.2keywords = gland (Clic here for more details about this article) |
8/223. Thyroid papillary carcinoma arising in ectopic thyroid tissue within a branchial cleft cyst.A case of papillary carcinoma arising in ectopic thyroid tissue within a branchial cleft cyst is described. A 46-year-old woman presented with a 2.0 x 2.0 cm mass in her left lateral neck. The excised mass showed a cystic lesion with a thyroid papillary carcinoma. Following a lateral cervical cystectomy, subsequent thyroid gland and lymph nodes dissections were performed. Pathological examination showed an adenomatous goiter and no primary carcinoma in the thyroid gland, as well as metastatic papillary carcinoma in the lymph nodes. Two cases of thyroid papillary carcinoma arising in ectopic thyroid tissue within a branchial cyst have been reported previously, but no lymph node metastases were recognized. The first case of papillary carcinoma arising in ectopic thyroid tissue within a branchial cleft cyst, and accompanied by lymph node metastasis is presented.- - - - - - - - - - ranking = 0.4keywords = gland (Clic here for more details about this article) |
9/223. Tumor-to-tumor metastasis to follicular variant of papillary carcinoma of thyroid.OBJECTIVE: To describe and document tumor-to-tumor metastases in the thyroid gland. methods AND RESULTS: In this series we describe 3 cases of tumor-to-tumor metastasis in which the recipient tumor was a follicular variant of papillary thyroid carcinoma. The donor tumors and sites were small cell carcinoma of the lung, neuroendocrine carcinoma probably of pancreatic origin with initial presentation as liver metastasis, and clear cell carcinoma of the kidney with metastasis to liver and pancreas. The donor tumor cells infiltrated the substance of the follicular variant of papillary thyroid carcinoma, the nontumorous thyroid parenchyma, and the lymphovascular spaces. Small cell carcinoma and neuroendocrine carcinoma showed positive reactivity for neuroendocrine markers and were negative for thyroglobulin and calcitonin. The follicular variant of papillary thyroid carcinoma showed positivity with thyroglobulin and cytokeratin 19. CONCLUSIONS: Although tumor-to-tumor metastases in thyroid gland are exceedingly rare, one should be aware of this phenomenon as the metastatic lesion may simulate a thyroid primary. history of a previous tumor and immunohistochemical stains can be helpful in distinguishing between primary and metastatic thyroid neoplasms.- - - - - - - - - - ranking = 0.4keywords = gland (Clic here for more details about this article) |
10/223. A case of extraadrenal pheochromocytoma associated with adrenal cortical nodular hyperplasia and papillary thyroid carcinoma.A 64-year-old woman was admitted in November, 1996 for fluctuating blood pressure. There was multinodular goiter in her neck. High urine VMA and serum aldosterone were noted. Computed tomography showed an oval lesion in the left adrenal gland. Left adrenalectomy was performed and the pathology was proved to be adrenal cortical nodular hyperplasia. Fluctuating blood pressure and high urine VMA persisted after the operation. CT scan of the abdomen revealed a soft tissue mass in lower abdomen. The patient was admitted again in September, 1997. Laboratory examinations showed normal serum aldosterone, normal plasma renin activity and high urine VMA. Aspiration cytology of the thyroid gland disclosed papillary thyroid carcinoma. [131I]-metaiodobenzylguanidine image revealed a high uptake lesion in the right L-3 paravertebral area. Tumor excision and thyroidectomy were performed. The pathology was reported as extraadrenal pheochromocytoma and papillary thyroid carcinoma. Papillary thyroid carcinoma is rarely associated with pheochromocytoma. To our knowledge, this paper is the first report of a patient with extraadrenal pheochromocytoma associated with papillary thyroid carcinoma and adrenal cortical nodular hyperplasia.- - - - - - - - - - ranking = 0.4keywords = gland (Clic here for more details about this article) |
