Small cell carcinoma of larynx has been reported as a rare disease occurring in 0.5% of larynx cancer. This tumor is known as one of the most lethal of all malignancies and associated with early recurrence and distant metastasis, leading into death. We experienced a case of a 70-year old male patient, who had admitted for sore throat and dysphagia and diagnosed as small cell carcinoma of larynx. We present small cell carcinoma of larynx with a brief review of literature.

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.

Lymphoepithelial carcinoma is an extremely rare malignant tumor, especially those localized at the head and neck region. The histological prototype of lymphoepithelial carcinoma is undifferentiated nasopharyngeal carcinoma. Herein, we report a case of a tumor localized in the left submandibular gland in a 20-year-old male. The tumor mass was surgically excised with the submandibular gland, and the specimen was pathologically confirmed to be lymphoepithelial carcinoma.

A Phase II study of UFT which is a mixture of Tegafur and Uracil was conducted in two institutions during past two years. Ninty-four patients of head and neck squamous cell carcinoma entered this trial, of which sixty-eight were evaluated. Among those, thirty-six cases were previously untreated and thirty-two cases were recurrent UFT was administrated orally at a daily dose of $400mg/m^2$ for eight weeks. The results were as following: 1) Overall response was 30.88%, but for 38.36% for 36 cases of the untreated cases, 21.88% for 32 cases of recurrent cases. 2) UFT was more effective in early stage and well differentiated squamous cell carcinoma and UFT tended to reduce the tumor size maximally at fourth or fifth week 3) There was no serious side effects except mild gastrointestinal disturbances such as nausea and vomiting, which were recovered immediately after stop or reducing a daily dose. Therefore, UFT therapy is clinically effective for head and neck squamous cell carcinoma and also may be useful for combination or palliative chemotherapy because of mild side effects.

Neuroendocrine carcinomas are rare neoplasms of the hypopharynx. Neuroendocrine neoplasms are divided into four main types : carcinoid, atypical carcinoid, small cell carcinoma and paraganglioma. The diagnosis is primarily based on light microscopy and should be confirmed by immunohistochemical investigation. Small cell neuroendocrine carcinoma of the hypopharynx is extremely uncommon tumor and surgical results for this tumor have been disappointing. Chemotherapy and radiotherapy currently appear the most effective forms of therapy. We report our case of small cell neuroendocrine carcinoma of the hypopharynx with the brief review of literatures.

Mucoepidermoid carcinoma is most frequent malignant tumor of parotid gland. However, mucoepidermoid carcinoma arising from pleomorphic adenoma has been disputed and rarely reported. 54-year-old woman with pleomorphic adenoma underwent superficial parotidectomy. And 15 years later, she diagnosed mucoepidermoid carcinoma at the same side. We report the case with a review of literature.

Oncocytic neoplasm of the head and neck region accounts for approximately 1% of all salivary gland tumors, but only 5% of oncocytic neoplasm is malignant. Oncocytic carcinoma arising in the submandibular gland is exceedingly rare. We encountered a sixty seven-year-old male patient who presented with multiple mass in the right neck. Fine needle aspiration biopsy revealed a salivary gland tumor of predominantly oncocytic form, and a differential diagnosis included oncocytic adenoma or mucoepidermoid carcinoma. A right submandibular gland resection and modified radical neck dissection were performed. Histologically, the tumor cells showed nuclear pleomorphism, and stromal invasion, which were compatible with oncocytic carcinoma. After surgery, the entire neck region was irradiated. Seventeen months after the initial surgery, multiple metastases to the bone and lung were detected from the incidental pathologic bone fracture of the right humerus; palliative chemotherapy was performed to resolve this. We report a case of oncocytic carcinoma in the submandibular gland with a review of literature.

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.

Squamous cell carcinoma, which is a common primary head and neck malignant neoplasm that is usually restricted to the mucosal surfaces of the upper aerodigestive tract and skin, is very unusual in the major salivary gland. Among them, few cases are regarded as primary carcinomas. In this article, we present two cases of squamous cell carcinoma in the parotid gland, who first presented with painful mass on infraauricular area.

Background and Objectives: Because of squamous cell carcinoma of the head and neck undergoes a generally poor hospital course, the prognostic significance of the squamous cell carcinomas in head and neck have been evaluated to identify those features associated with aggressive biologic behavior according to the immunologic and histopathologic characteristics. Materials and Method: To assess the significance of EGFR, c-erbB-2, p21 and p53 protein in head and neck tumors and their correlation with prognostic factors, samples from 74 patients with squamous cell carcinomas of larynx, pharynx, and oral cavity were studied immunohistochemically. Results: EGFR, c-erbB-2, p21, and p53 protein were expressed 94.6%, 24.3%, 85.1%, and 55.4% in 74 cases of head and neck squamous cell carcinoma, respectively. The positive expression of EGFR was associated significantly with clinical stage and the negative expressions of p21 was associated significantly with histopathologic differentiation. There were no significant relationships between the reactivity of EGFR, c-erbB-2, p21, and p53 protein. Conclusion: The expression of EGFR, c-erbB-2, p21 and p53 protein could be related to oncogenesis, and the expression of p21 and EGFR protein can be used as a prognosticator in head and neck squamous cell carcinoma under certain limitations, but c-erbB-2 and p53 protein expression alone is not enough for evaluating prognosis of the carcinoma.
