Paraganglioma is a rare benign neuroendocrine tumor arising from the paraganglia of the autonomic nervous system. Paraganglioma occurs mainly in the carotid body, jugular foramen, and vagus nerve in the head and neck region. Herein, we report a case of paraganglioma of the submandibular region that has not been reported. This case highlights paraganglioma as a rare differential diagnosis for submandibular region tumors.

Identification and protection of the facial nerve is very important in the proper operation of the parotid tumor. Posterior approach which finds main trunk of the facial nerve by surgical landmark such as tragal pointer, tympanomastoid suture, and posterior belly of digastric muscle is most commonly used. In case of posterior located tumor, inferior approach may be used, in which the retromandibular vein is followed from the neck and inferior branch of the facial nerve is located. In general, the facial nerve lies superficial to the retromandibular vein. But we experienced the anomalous relationship of the facial nerve and the retromandibular vien. We report this case with a literature review.

A 45-year-old Korean male with laryngotracheal papilloma was treated using a 532-nm diode laser at six watts with a pulse width of 25 milliseconds. Two months after the laser treatment, the resected region was well-healed without significant scar contracture. This outcome suggests that a 532-nm diode laser can be a safe and effective treatment for laryngotracheal papilloma.

The patient a 24-year-old male, was shown to have milliary shadows on chest radiographs from the age of 20. He was temporarily treated for pulmonary tuberculosis without success. He had left thyroid mass and lymph node metastases in neck CT scan which was taken after admission but fine needle aspiration result in scanty cellularity. He underwent total thyroidectomy with left modified radical neck dissection and right selective neck dissection under the impression of differentiated thyroid cancer with bilateral neck metastases. Then he underwent 131I ablation treatment and postoperative whole body 131I scintigraphy revealed diffuse intensive uptake in the bilateral lung fields, demonstrating that the pulmonary lesions were metastases of the thyroid cancer.

Malignant salivary gland tumors only represent 0.08% of all childhood tumors. Especially, nasopharyngeal mucoepidermoid carcinoma(MEC) in pediatric age is an extremely rare malignancy. We hereby report a case of nasopharyngeal MEC in 5 year-old female patient. The patient underwent the complete removal of the tumor by endonasal endoscopic approach. Adjuvant postoperative radiotherapy was not considered. After 3.5 years of follow-up, there are no sign of recurrence and metastasis. Minor salivary gland tumor must be considered as a differential diagnosis of angiofibroma in nasopharynx in pediatric age. To our knowledge, the case we describe is the third case of nasopharyngeal MEC in pediatric age reported in literature.

Solitary fibrous tumor (SFT) is rare mesenchymal tumor usually arising from pleura. SFT can be found at all anatomic site in our body but incidence of SFT is much lower in head and neck region especially at lower neck area. We found a case of SFT that presented as a lower neck mass in a 41-year old woman. Ultrasonography showed a 3×1cm sized hypoechoic mass in the intermuscular fat plane of left lower neck, and computed tomography showed a well circumscribed, low-density mass with contrast enhancement. Fine needle aspiration showed no malignant cells with abundant red blood cells, but it was not possible to completely rule out malignant tumors or nodules clinically. Surgery was performed to make a definitive diagnosis and histopathology showed tightly packed, round to fusiform cells with staghorn shaped vessels at microscopic examination. The tumor cell were positive for CD34 but negative for CD31 and S-100 protein.

Background and Objective：A post-operative hypertrophic scar of the anterior neck is the leading complaint of the patients who underwent conventional thyroid surgery. In order to minimize the post-operative scar of the anterior neck, we performed thyroidectomy via axillary approach using operating microscope and a specialized retractor to determine technical feasibility. Patients and Methods：From January 2005 to December 2006, we performed thyroidectomy via axillary approach under operating microscope(f=400mm, ${\times}2.5$；OPMI $pico^{(R)}$；Zeiss, Germany) for benign unilateral nodule in 25 cases(all female, average age 34.5yrs). Under general anesthesia less than 7cm of skin incision was made in the axilla of ipsilateral side. A subcutaneous tunnel went over the pectoralis major muscle and the clavicle, and then through the sternocleidomastoid muscle and sternothyroid muscle was excised. The area around the thyroid was sufficiently dissected, and then a retractor designed for exposure via axillary approach was placed within the tunnel and under operating microscope thyroidectomy was performed. Results：There were 17 cases of thyroid nodulectomy and 8 cases of subtotal lobectomy. The mean average operative time was 102.64minutes. Postoperative complications included one case of postoperative bleeding, one case of temporary vocal cord paralysis, two cases of delayed wound healing, two cases of paresthesia of shoulder and arm, and two cases of hypertrophic scar of the axilla. Postoperative histopathology includes 17 cases of adenomatous hyperplasia, six cases of cyst, and two cases of follicular adenoma. For all cases hospitalization period was two days. Conclusion：Thyroidectomy via axillary approach under operating microscope has a good cosmetic advantage without a post-operative scar of the anterior neck. The procedure is simple due to direct vision using operating microscope, easy to identify important structures by magnifying them, and therefore surgical time can be reduced.
