  • 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 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.

  • Primary intracranial squamous cell carcinoma is extremely rare, with most cases arising from a preexisting benign epidermoid cyst. We report a rare case of primary intracranial squamous cell carcinoma in the brain stem with a cerebellopontine angle (CPA) epidermoid cyst. A 72-year-old female suffered from progressive left hemiparesis, difficulty in swallowing, and right hemifacial numbness. Diffusion-weighted magnetic resonance imaging revealed a high signal intensity (SI) lesion in the CPA region and an intra-axially ring-enhanced cystic mass in the right brain stem with low SI. Whole-body positron emission tomography showed no evidence of metastatic disease. The histological findings revealed a typical epidermoid cyst in the CPA region and a squamous cell carcinoma in the brain stem. We speculate that the squamous cell carcinoma may have been developed due to a chronic inflammatory response by the adjacent epidermoid cyst. The patient underwent a surgical resection and radiotherapy. After 12 months, she had no evidence of recurrence.

  • Squamous carcinomas of the thyroid gland are extremely rare, and its clinical course is very aggressive. It has poor prognosis, similar to that of anaplastic carcinoma. These tumors are radioresistant and often rapidly fatal. It is considered to originate from the follicular epithelium at present. Recently, authors had experienced 63-years old female patient, proved to be primary squamous cell carcinoma of the thyroid. We report this patient with a review of a literature.

  • Primary intraosseous carcinoma(PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa. The squamous cell carcinoma within the bone can be presumably developed from residues of the odontogenic epithelium, therefore, it is seen in the jaw only. Metastatic carcinoma from another primary site should be excluded in the diagnosis of Primary Intraosseous Carcinoma. This is a case of 62-year-old man, who initially diagnosed as odontogenic cyst on maxilla, but its pathologic examination was diagnosed as squamous cell carcinoma with odontogenic cyst. We treated this patient with partial maxillectomy, modified radical neck dissection(mRND), and postoperative radiation therapy.

  • A primary squamous cell carcinoma of the thyroid is extremely rare disease. We evaluated this disease by fine needle aspiration cytology in a 43 year-old female. On physical examination, the thyroid was moderately enlarged and palpated with hard consistency. The cytologic aspirate revealed nests of squamous cells, malignant squame and thyroid follicular cells in the necrotic background. We diagnosed this tumor as squamous cell carcinoma with cytologic evidence. Surgically resected thyroid revealed well differentiated squamous cell carcinoma. Immunohistochemical staining for antithyroglobulin proved that this tumor was primary in origin and clinical study confirmed this lesion to be of primary thyroid origin rather than metastasis or direct invasion from contiguous structures.

  • Squamous cell carcinoma originating in the parotid gland has rare occurrence. The primary squamous cell carcinoma of the parotid gland comprise about 0.3% and 9.8% of all parotid malignant tumor. We investigated the clinical behavior and treatment outcome of patients with primary squamous cell carcinoma of the parotid gland. We reviewed all cases of possible primary squamous cell carcinoma of the parotid gland treated at Yonsei Cancer Center, Seoul, Korea, from 1981 through 1995. A total of 128 had primary parotid malignancy. Metastatic squamous cell carcinoma and mucoepidermoid carcinoma were excluded in this study. Ten cases of primary squamous cell carcinoma of the parotid gland were identified. 6 cases of them are men & 4 cases are women. The age of patients ranged from 31 to 68 years with median age of 55 years. On physical examination, 5 cases had palpated cervical neck node and 6 cases had facial nerve palsy. Staging was done according to the current guidelines established by the American Joint Committee on Cancer (1992). Two cases were stage I, 1 in stage III, and 7 in stage IV. Six cases were performed operation and postoperative radiation therapy. Four cases were treated by curative radiation therapy, dose of more than 65 Gy on parotid gland region. The 5 year actual survival rate and the 5 year disease free survival rate were 30.8%, and 40.0%. Initial complete response rate was 70% for all patients. Local failure were occurred 3 of 7 patients with local controlled cases, failure sites were primary site, ipsilateral cervical neck node, contralateral supraclavicular node. Most recurrences developed within 1 year of initial treatment. Distant metastasis was appeared 2 of 3 patients who did not achieved local control. Primary squamous cell carcinoma of the parotid gland occured infrequently. A retrospective study at the Yonsei Cancer Center indicates incidence of 7.8%. At diagnosis, advanced stage, neck node presentation, facial nerve paralysis were associated with a poor prognosis. These results may suggested that radical surgical excision may be treatment of choice and that planned postoperative radiotherapy may be bendicial for reducing locoregional recurrence rates.

  • The existence of primary branchiogenic carcinoma is controversial. In 1950, Martin et al. established four criteria for the diagnosis of primary branchiogenic carcinoma. In 1989, Khafif et al. proposed new modified criteria, which are currently most recognized in the literature. A 54-year-old woman presented the well-defined, fluctuant, painless mass on her left neck and underwent a complete excision under the clinical diagnosis of the branchial cleft cyst. The initial pathological impression was a branchiogenic squamous cell carcinoma. However, it did not coincide with a true primary branchiogenic carcinoma clinically. After the guided biopsy of suspicious areas found a squamous cell carcinoma of the tongue base, the patient was treated by combination chemotherapy with radiotherapy. Thus, we report this case with a review of the literature.

  • Primary intraosseous squamous cell carcinoma is a rare malignant central jaw tumor derived from odontogenic epithelial remnants. Predominantly, it affects mandible, although both jaw bones may be involved. This report describes a 60-year-old man who was initially misdiagnosed with a periapical infection related to the right lower wisdom tooth. After four months, the patient presented to a private dental clinic with a massive swelling at the right side of the mandible. Panoramic radiographs and advanced imaging revealed a lesion with complete erosion of the right ramus, which extended to the orbital floor. A biopsy from the mandibular angle revealed large pleomorphic atypical squamous cells, which is the primary microscopic feature of a poorly differentiated squamous cell carcinoma.

  • Primary squamous cell carcinoma of thyroid is a very rare malignant tumor with poor prognosis. It is usually diagnosed as an advanced disease infiltrating adjacent organs, and characterized by aggressive clinical course with an average postoperative survival time of less than 1 year. Recently, we had a 79- year-old woman with a painful neck mass who was diagnosed as primary squamous cell carcinoma of thyroid gland. She underwent total thyroidectomy and selective neck dissection(level III, VI) with no further postoperative managements such as radiation therapy or chemotherapy; she died of poor general condition and pneumonia resulting from rapid progression of the lesion on the 38th day after surgery. We report this case with a review of relevant literatures.
