  • Background and Objectives: To determine if laser endoscopic microsurgery is a reliable and appropriate approach in the treatment of laryngeal carcinomas. Materials and Methods: Retrospective study of 62 patients treated with CO2 laser from June 1988 to November 2000 at Seoul National University Hospital for laryngeal squamous cell carcinoma. All patients were treated with curative intention. Fifty three untreated patients with laryngeal carcinoma (39 glottic and 14 supraglottic carcinoma patients) had primary carbon dioxide laser microsurgery. Nine radiation failure patients were treated. Postoperative radiotheray was done for 17 patients. Neck dissection was performed simultaneously for 4 supraglottic cases with cervical nodal metastasis. Mean follow-up duration was 40 months. Results: In primary laser surgery group, distribution of tumors (American Joint Committee on Cancer, 1997) were 38 cases with Tl, 13 cases with T2, 2 cases with T3. Cure rate was 88.7%(47/53) and local control rate was 92.5%(49/53). Larynx was preserved in 94%(50/53) of patients. The overall 5-year survival rate(Kaplan-Meier) was 81.5%. In radiation failure group, 56% of patients were recurred after laser surgery. Conclusion: Laser surgery could be a better treatment modality for early laryngeal cancers and selected advanced cases. Additional radiation therapy should be considered if resection margin is not satisfactory.

  • Objectives : Well differentiated thyroid carcinoma(WDTC) has relatively good prognosis. But recurrence is associated with increased morbidity and mortality, and always results in reoperation. So it is important to evaluate the risk factors relative to the recurrence. The aim of this study is to evaluate the risk factors of recurrence. Materials and Method : Two hundred seventeen patients who had undergone thyroidectomy and proved as WDTC from January 1999 to December 2004 was included in the study. We reviewed patient-related and tumorrelated factors respectively and analyzed the correlation with tumor recurrence. Results : Fourteen patients from two hundreds seventeen had recurred. Recurrence rate was 6.5%, and average interval of recurrence was 28 month. Male, age over 45, multiple mass, and advanced TMN stage patient group show higher recurrence rate, but no statistical significance. However, the recurrence rate of lymph node metastasis, tumor size>1.5cm, and extracapsular invasion group were statistically high. Conclusion : Lymph node metastasis, tumor size and extracapsular invasion are significant risk factors related to the recurrence of WDTC.

  • Epidermal cysts are generally benign tumors that usually originate from the skin caused by inflammation of hair cortex and proliferation of epidermal cells within the dermis; however, for these cysts to occur in the bony external auditory canal (EAC) is rare. They are often present as a solitary, painless lesion and usually asymptomatic and the diagnosis depends on the results of the histological examination. In treatment, the cyst wall must be completely removed surgically. We recently encountered a 82-year-old male with a mass in the right EAC. An otoscopic examination showed a polypoid mass on the bony EAC, which was finally diagnosed as epidermal cyst after an initial misdiagnosis as EAC carcinoma. We report the rare, unique case with literature review.

  • We have experienced 3 cases of papillary carcinoma of the thyroid gland seen as lateral neck cyst, Usually cystic lesions of the neck have been considered as benign lesions from clinical viewpoint. The usual differential diagnosis includes branchial cleft cyst, cystic hygroma, dermoid cyst, cold abscess(tuberculous lymphadenitis) and cavitating squamous cell carcinoma. A lateral neck cyst as the sole presenting complaint of the papillary thyroid carcinoma is very rare. Preoperative diagnosis of lateral neck cyst is often diagnostic dilemma. Fine-needle aspiration cytology can be helpful in detecting the cancer cells and in demonstrating the nature of the fluid component of the lateral neck cyst. Presence of brown murky fluid from the aspirated fluid is highly suggestive of thyroid carcinoma. The thyroid scans and B-mode ultrasonography mayor may not be helpful to detect the primary focus of the thyroid gland. We suggest that a patient with a lateral neck cyst in adult age group should be considered to be a possibility of underlying thyroid carcinoma presanting as lateral neck cyst.

  • Necrotizing sialometaplasia was defined by Abrams et al. in 1973 as a reactive necrotizing inflammatory process involving minor salivary glands. Prior to recognition of necrotizing sialometaplasia as a benign, self-limited lesion, it was all too often diagnosed as either squamous cell carcinoma or mucoepidermoid carcinoma and had been improperly treated because of its clinical and histological resemblance to malignancy. We report two cases of necrotizing sialometaplasia. One case involved a 56-year-old female who developed a necrotizing sialometaplasia in association with palato-pharyngeal flap wound after excision of soft palate cancer and reconstruction. Another case involved a 55-year-old male who had a soft palate mass.

  • Metastatic tumors of the oral cavity are uncommon. Most of them are located in the mandible while only small percentage are found within the soft tissues. The common sites of metastases to the soft tissue of oral cavity were the tongue and gingiva and among the tongue, the base of tongue was most common. An explanation of the predilection may be due to a richer vascular supply within base of tongue. The authors have recently experienced a case of small cell lung carcinoma with base of tongue metastasis in a 81-year-old male who had foreign body sensation at swallowing and muffled voice for 2 months. So, we present this case with the review of literatures.

  • Papillary thyroid carcinoma (PTC) is the most prevalent type of thyroid cancer. In contrast, thyroid lymphoma is a very rare disease. Concurrent onset of both is very rare in the thyroid gland. Ultrasound (US)-guided Fine needle aspiration (FNA) is a useful diagnostic tool, but occasionally pathology results may change after the surgery. A 56 years old woman visited with Hashimoto's thyroiditis and nodule on the thyroid gland isthmus on US exam. US-guided FNA was performed at thyroid nodule and diagnosed as PTC. The patient underwent total thyroidectomy. The pathological findings revealed a mucosa associated lymphoid tissue (MALT) lymphoma accompanied with PTC. Authors report this unusual case with a review of literature.

  • Objectives: Minimal improvement in the long-term survival of head and neck cancer(HNC) patients has occurred despite a multitude of advances in the control of loco regional disease and a second primary malignancy(SPM) contribute to the continued poor prognosis for the HNC patients. This study was performed in order to identify the clinical characteristics of SPM in the HNC patients. Materials and Methods: The medical records of 354 patients of head and neck squamous cell carcinoma that were followed up after initial treatment during the period of 1987 through 1994 were reviewed. This study examines the medical records of 354 patients with squamous cell carcinoma of the head and neck, of whom 26 subsequently developed a second neoplasm. Results: The actuarial SPM rate was 7.3%, and median time to presentation for the SPM was 26.8 months. The SPM were more likely to occur in male patients who had oral cavity index tumors. Patient whose index tumor was small at diagnosis had a greater chance of developing a second tumor as did those with no cervical lymph node metastases to the neck. Initial treatment modality was not associated with an increased risk of developing a second tumor. The commonest sites for the SPM were the lung and other head and neck area. The 3-year survival for patients who developed a secondary tumor from the time of its diagnosis was 27.8%. Conclusion: The SPM in the head and neck cancer patients are not uncommon and early detection of the SPM will contribute to increase the long-term survival of HNC patients.

  • Salivary gland tumors comprise almost 5% of head and neck malignancies, and minor salivary gland tumor which account for 10-15% of all salivary gland neoplasm are infrequently malignant. The mucoepidermoid carcinoma (MEC) is second most common tumor in minor salivary gland. It usually presents as a painless, rubbery-hard or soft mass, which may be fixed or mobile into the underlying structure. The predilection sites of intraoral MEC are palate, cheek, mandible, lip, and tongue, etc. There are very few published reports of MEC occurred in retromolar trigone. Only one case has been reported so far. Recently, we experienced a-70-year old man with a mass in retromolar trigone, which was finally diagnosed as MEC. We report the unique case with literature review.

  • Among a variety of malignant types for parotid gland tumors, intracapsular carcinoma ex pleomorphic adenoma which is classified as a non-invasive tumor has been reported rarely. We report a case of a 69-years old patient, who presented with a left parotid mass that was detected 30 years ago. Fine needle aspiration biopsy result of the mass was "suggestive of pleomorphic adenoma". Superficial partial parotidectomy was performed for the mass and the permanent pathologic finding was "intracapsular carcinoma ex pleomorphic adenoma" which was a salivary ductal carcinoma with well-preserved myoepithelial cells surrounding the malignant epithelial cell clusters. Surgical resection is the main treatment modality for the treatment of intracapsular carcinoma ex pleomorphic adenoma. Herein, we present the case with a review of literature.
