A case of squamous cell carcinoma of the thyroid gland associated with esophageal carcinoma is presented A squamous cell carcinoma of the thyroid gland is rare and is prognosis is poor. The histogenesis of squamous cell carcinoma is not clear, but at present, it is believed that most cases arise from the follicular epithelium It is very important to know whether squamous cell carcinoma of the thyroid is primary or secondary. Thus, the possibility of squamous cell carcinoma in the thyroid being the result of a metastasis or extension from a primary tumor in the trachea or esophagus must always be ruled out and intensive evaluation should be required to confirm the diagnosis of this disease. We report a squamous cell carcinoma of the thyroid associated with esophageal cancer with brief review of literature.

Thyroid carcinomas are usually classified as papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma. Among the thyroid carcinomas, the incidence of medullary and anaplastic thyroid carcinoma is low, but the rate of lymph node & distant metastasis from them are more common compared to other types. Follicular thyroid carcinoma has a low rate of lymph node metastasis as 10% and has a high occurrence of hematogenous metastasis to lung, bone, brain and liver. Papillary thyroid carcinoma accounts for $60{\sim}70%$ of whole thyroid carcinomas and the cervical lymph node metastasis is $21{\sim}81%$ including micrometastasis, but the distant metastasis is rare. In the case of bone metastasis, follicular type reveals most frequent, and the rate is about 5%, and more likely to be found on vertebra, pelvis, ribs, femur, and skull. The clinical symptoms of bone metastasis are pain, swelling, pathological fracture and radiologically osteolytic lesions can be observed. But distant metastasis of papillary thyroid carcinoma is very rare and especially, bone metastasis has hardly been reported. The treatment modalities of metastatic thyroid carcinoma to mandible are known as follows : thyroidectomy to treat primary site, resection of the affected site of mandible, external beam radiotherapy and radioiodine therapy etc.

We have experienced a case of occult papillary thyroid carcinoma presenting as an anterior mediastinal mass in a 40-year-old man. The CT scan revealed a huge mass behind the manubrium of the sternum but the ultrasound examination failed to detect any lesion and developmental defect in the thyroid. Excision of the mediastinal mass and total thyroidectomy were carried out. Histologically, the mediastinal mass turned out to be papillary carcinoma without any portion of the normal thyroid tissue or normal lymph node tissue and the thyroid gland showed a tiny papillary carcinoma with the diameter of 0.3cm. Although a mediastinal mass as the sole presentation of the thyroid carcinoma is very rare, we suggest that a mediastinal mass should be added to the list of possible metastatic thyroid carcinoma.

Simultaneous occurrence of medullary and papillary thyroid carcinomas in the same gland is very rare. In fact. there are only 18 cases of simultaneous occurrence of medullary and papillary thyroid carcinomas in the literature. We report a case of simultaneous medullary and papillary carcinoma of thyroid gland. A 67-year-old woman was diagnosed with medullary carcinoma of right lobe of thyroid gland and papillary carcinoma of left lobe of thyroid gland by fine needle aspiration cytology. Total thyroidectomy, anterior neck dissection, bilateral modified radical neck dissection and tracheotomy was undertaken. The tumor metastasized to regional lymph node and extrathyroidal muscle invasion of left papillary carcinoma was also revealed by pathological report. This report describes a case of thyroid carcinoma that demonstrated both medullary carcinoma and papillary components in the thyroid with lymph node metastasis.

The distant metastasis is found out in about 25-57% of the patients with renal cell carcinoma at the time of diagnosis. But, the incidence of metastases to the head and neck region, especially to the thyroid gland, is rare. Most of patients with metastatic renal cell carcinoma to the thyroid gland are asymptomatic at presentation as patients with primary thyroid carcinoma. In the presence of clear cell tumor of the thyroid gland, the diagnostic considerations must include metastatic renal cell carcinoma. We report a case of thyroid metastasis from renal cell carcinoma at the time of diagnosis.

Metastasis from primary cancer to the thyroid is uncommon in breast cancer. Here we present a case of lobular breast carcinoma that metastasized to the thyroid. A 54-year-old woman without symptoms was admitted to our institution for staging of the lymph node above the left clavicle. An $^{18}F$-fluoro-deoxy-D-glucose positron emission tomography scan was performed for staging, and low uptakes were observed in the left supraclavicular and cervical lymph nodes. High uptake was seen in the posterior and lower left lobe of the thyroid. Histologic findings indicated lobular breast carcinoma (positive GATA3, loss of E-cadherin expression) metastatic to the thyroid with a luminal profile. Immunohistochemical analysis was negative for primary thyroid or parathyroid carcinoma. To our knowledge, this is the first report of a patient presenting a metastatic invasive lobular carcinoma in the thyroid and lymph nodes without a prior diagnosis of breast cancer.

Papillary carcinoma of thyroid is the most common thyroid carcinoma carrying better prognosis than the other thyroid carcinoma. Among the variants in the papillary thyroid carcinoma, the tall cell variant and diffuse sclerosing variants have more aggressive behavior than the classic papillary carcinoma. Recently, a new variant of papillary carcinoma has been reported which was named warthin-like tumor of the thyroid because of its close histologic resemblance to a tumor encountered in the salivary gland, carrying favorable prognosis. Since then, in English literature, a few cases have been reported, but in Korea have not been reported yet. We report a case of warthin-like tumor of the thyroid. A 38 year-old woman who had neck mass, was administered for thyroid surgery due to suspicious thyroid cytology. Right total thyroidectomy and left subtotal thyroidectomy with central compartment node dissection was performed. Histologic diagnosis was made as a Warthin-like tumor of the thyroid.

Thyroid carcinoma occuring as a second primary associated with head and neck squamous cell carcinoma (SCC) is unusual. This report presents a synchronous thyroid carcinoma and squamous cell carcinoma in the anterior palate region of a 41-year-old man. The clinical, radiologic, and histologic features are described. At 10-month follow-up after operation, no evidence of recurrence and metastasis was present.

Lymphoepithelioma-like carcinoma exhibits immunohistochemically similar features to lymphoepithelioma and commonly occurs in the skin, salivary gland, breast, lung, gastrointestinal tract, liver, urinary tract, prostate, vulva and vagina. Lymphoepithelioma-like carcinoma from the thyroid gland is extremely rare. We recently experienced a case of lymphoepithelioma-like carcinoma of thyroid gland in a 28-year-old female, who presented a thyroid nodule that was suspicious of papillary carcinoma. We report this unusual case of lymphoepithelioma-like carcinoma of thyroid gland with a brief review of literature.

Mutation of the P53 tumor suppressor gene playa major role in the development of many carcinomas, namely in the colon, breast and bladder, whereas the role played by such mutations in thyroid carcinogenesis remains controversial. Vascular endothelial growth factor (VEGF) induces proliferation of endothelial cells, stimulates angiogenesis, and increases vascular permeability. Increased VEGF expression has been associated with poor clinical outcomes in many malignancies E-cadherin, a calcium-dependent transmembrane glycoprotein, is an adhesion molecule Expression of p53, VEGF and E-cadherin was assessed immunohistochemically in 19 tall columnar variant of papillary carcinoma, 24 common papillary carcinoma and 7 follicular carcinoma. The aim of this study was to evaluate the expression of P53,VEGF and E-cadherin as a potential maker for the prognosis of thyroid carcinomas. The results are as follows: 1) There were no significance in any clinical parameters examined among tall columnar variant of papillary carcinoma, common papillary carcinoma and follicular carcinoma. 2) The expression of P53 demonstrated low in tall columnar variant of papillary carcinoma, common papillary carcinoma and follicular carcinoma, but a significantly high in regional lymph node metastasis. 3) The expression of VEGF demonstrated a significantly high in regional lymph node metastasis than those without metastasis in papillary thyroid carcinoma. 4) The expression of E-cadherin demonstrated less often among papillary carcinomas with lymph node metastasis than in those without metastasis in papillary thyroid carcinoma. In conclusion, it is suggested that VEGF and E-cadherin will be useful for the diagnosis of thyroid carcinoma and serves as a biological marker for thyroid carcinoma lymph node metastasis.
