Follicular thyroid carcinoma with metastasis rarely manifests as spinal cord compression without any previous symptoms of its malignancy. This report describes a 64-year-old man with follicular thyroid carcinoma who presented initially with left arm motor weakness. Magnetic resonance images demonstrated severe cervical cord compression by a mass with destruction of C4 vertebra. Corpectomy of C4 and anterior interbody fusion was carried out. Histopathological study revealed a metastatic follicular carcinoma of the thyroid. We present our case, especially focused of its possible pathophysiology, with review of pertinent literatures.

유방암 검사와 함께 시행한 갑상선 선별 초음파 검사에서 나타난 전형적인 갑상선 유두암의 소견은 경계가 불분명한 고형의 저에코 결절로 나타나고 점상 혹은 미세석회화를 보일 수 있어 이러한 결절에서는 조직 검사를 통한 확진이 필요하다.

Insular carcinoma(poorly differentiated thyroid cancer) is defined as a aggressive, follicular-derived thyroid carcinoma with behavior intermediate between follicular/papillary and anaplastic carcinomas. It was described by Carcangiu in 1984, but its prognosis, classification and the origin is not yet clear. And preoperative fine needle aspiration cytology of insular carcinoma has not been satisfactory. We experienced a case of advanced thyroid insular carcinoma with invasion of the sternum. So we intend to present the case with a review of the related literatures.

Multiple primary tumors in the head and neck are not uncommon, however those in the thyroid and the larynx are known to be very rare. In most cases of multiple primary tumors involving the thyroid and the larynx, lesions are observed usually simultaneously and thyroid tumors are found incidentally during the laryngeal tumor surgery. In rare cases, thyroid tumors are found metachronously after radiation therapy of laryngeal cancer. The authors recently experienced a case of multiple primary tumor involving the thyroid and the larynx, in which thyroid papillary carcinoma was the index tumor and the laryngeal squamous carcinoma was the meatachronous second tumor. Both tumors showed aggressive local extension and regional nodal meatastasis with tumor collision in the same node. The patient died of recurrent or of residual squamous carcinoma shortly after main surgical treatment index thyroid cancer.

Primary squamous cell carcinoma of the thyroid gland is a very rare event, representing much less than 1% of all malignant tumors of the thyroid gland. The cancer is characterized by rapidly progressive clinical course in spite of its differentiated morphologic features. In most cases, a squamous epithelium is believed to be a result of metaplasia of a follicular epithelium, although in rare exceptions, it can originate from a remnant of the thyroglossal duct or ultimobranchial body. Squamous cell carcinoma of the thyroid gland can occur in a pure form or mixed with adenocarcinoma. Because their clinical behavior is more aggressive than that of other malignant neoplasm of thyroid gland, the tumor should be treated more vigorously at its initial stage. Recently, authors experienced one case of primary squamous cell carcinoma of the thyroid gland. We report our case with a brief review of literature.

Primary thyroid lymphoma is rare and accounts for less than 5% of all thyroid malignancy. The clinical presentation includes a rapidly enlarging neck mass, associated with dysphagia, dyspnea or hoarseness. The most common histologic type is diffuse large B cell non-Hodgkin's lymphoma. Papillary thyroid carcinoma is the most common type of thyroid malignancy. Co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma is very rare. Recently, we experienced a case with co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma in a 79-year-old woman, who had tuberculous lymphadenitis presented as lateral neck mass. We present this case with a review of the literature.

Anaplastic carcinoma of the thyroid (ACT) is a rare subtype of thyroid neoplasm. This tumor represents approximately 5-10% of all thyroid malignancies and has poor prognosis ACT often arises on a long-standing thyroid nodule and has been documented to be associated with a variety of more well-differentiated thyroid carcinomas. We experienced a case of anaplastic thyroid carcinoma who had had about a year history of thyroid getter. The patient had been injected with sclerosing agents in treatment of preexisting golfer. The ACT in this case had varied cytologic and histologic appearances: pleomorphic, giant cell, spindle and squamoid. Immunohistochemically, strong cytoplasmic positivity for cytokeratin was seen in all kinds of tumor cells. Ultrastructurally, the evidences of epithelial differentiation were seen such as intercellular junctions and tonofibrils.

Skin metastasis from papillary thyroid carcinoma is extremely rare. Due to similar histopathologic features, it is difficult to differentiate skin metastatic papillary thyroid carcinoma and some primary skin neoplasms without a clinical history. However, most of metastatic skin lesions showed a strong reactivity to the antithyroglobulin antibodies unlike primary skin neoplasms. Metastatic skin lesions must be completely removed and radiotherapy can be added. Investigators reported that prognosis of skin metastases from thyroid carcinoma is dismal and the average survival after it's diagnosis was only 19 months because distant metastases were often discovered at diagnosis of skin metastasis or during follow-up period. We report a case of skin metastasis from tall cell variant of papillary thyroid carcinoma. In our case, the anti thyroglobulin antibodies measured from cystic fluid from a skin lesion was more than 2000 IU/ml. Skin metastasis was diagnosed at 20 months after primary surgery for thyroid cancer and brain metastasis at 12 months after diagnosis of skin metastasis. Although skin metastasis is an ominous prognostic indicator in patients with thyroid carcinoma, a radical treatment for skin lesions and early diagnosis of distant metastasis could provide a chance to the patients to improve their survival.

Oxyphilic (Hurthle) cells have abundant eosinophilic granular cytoplasms and occur in both benign and malignant neoplasms of the thyroid gland. Most published studies described mainly oxyphilic tumors of follicular type, and reports on oxyphilic papillary thyroid carcinomas are rare. The oxyphilic variant of papillary carcinoma differs from the classic papillary carcinoma in its more aggressive biological behavior. We report a case of oxyphilic papillary carcinoma exhibiting exclusively oxyphilic cells in a follicular pattern without papillary structures. The pattern of papillary carcinoma was confirmed by fine needle aspiration material and lymph nodal metastasis, both of which revealed typicaled papillary structures with characteristic nuclear features, psammoma bodies, and oxyphilic cytoplasm.

Ectopic thyroid glands generally occur in the midline as a result of abnormal median migration, and their presence lateral to the midline is extremly rare. We report a 83-year-old male with anaplastic carcinoma admix papillary carcinoma in the extrathyroid area. We suspected left lateral neck metastasis on preoperative fine needle aspiration result and computed tomography. the patient underwent total thyroidectomy and left selective neck dissection(level II, III, IV, V). The patient was diagnosed as having an ectopic thyroid gland on the lateral neck with anaplastic carcinoma admix papillry carcinoma. The patient is alive without incident of tumor recurrence at 5month after surgery and radiotherapy.
