  • A choristoma is a tumor like mass of normal tissue in an abnormal location. Lingual osseous choristoma, previously known as osteoma of the tongue base, is rare entity. That is defined as a normal bone mass occuring in the soft tissue of either the skin or the mucosa of oral cavity. The cause of osseous choristoma of the tongue is still unknown, but only several theories have been suggested. Because of the rarity of this entity, our purpose is to add our case to the literature, and to discuss the nature of the disease.

  • Mucinous adenocarcinoma is rarely reported in head and neck region. In other organ, it usually occur in breast, gastrointenstinal tract and so on. The specific histologic findings of mucinous adenocarcinoma are the large amount of extracellular mucin and tumor cell nests such as floating in mucin pool. It may develop rarely in major or minor salivary gland, but only one case of mucinous adenocarcinoma originating from parotid gland was presented in south korea. We report a case of mucinous adenocarcinoma in the tongue base considered to develop from minor salivary gland with a review of literatures.

  • 호흡곤란에 대한 적절한 대처는 의사로서 숙지하여야 할 가장 중요하고도 기본적인 개념 중의 하나이다. 상부 기도에 발생하는 여러 가지 임상적 상황은 흔히 흡기성 천명을 동반하는 호흡 곤란으로 나타나고, 이에 대해 흔히 기도 삽관이나, 기관절개술 등이 행해 지지만, 그 발생 원인에 대해서 감별점들을 숙지하지 않으면, 원발 질환에 대한 합리적인 치료 뿐만 아니라 응급상황에서 적절하게 기도를 확보하는 데에도 문제가 생길 수 있다. 후두 상부에 일어나는 기도폐쇄의 상황은 비강에서부터 인두와 성문 상부, 식도 입구부에 이르는 해부학적 위치에 발생하는 다양한 질환들에 의한다. 비강과 비인두에는 pyriform aperture stenosis, choanal atresia, lacrymal duct cyst, 또는 teratoma나 encephalocele과 같은 질환이 발생할 수 있다. 구강, 인두부에서는 다양한 종류의 안면골격의 이상이나 설거대증, 또는 설갑상선, 갑상설관낭종, 또는 유피종등이 설기저부에 발생하기도 하고, 흔한 이유로 심한 편도-아데노이드 비대가 심각한 호흡곤란을 일으키기도 한다. 특히 소아에서는 이물의 가능성도 항상 염두에 두어야한다 이와 같이 기도 협착의 위치에 따라서 임상적 표현 양상이 구별될 수 있고, 또 부위에 따라 다양한 질환이 감별되어야 하므로 발생 위치에 따른 각 질환의 이해가 적절한 기도의 관리를 위해서 필수적이다.

  • A lingual thyroglossal duct cyst(LTGDC) is a rare congenital anomaly that account for only 0.5% to 2% of total thyroglossal duct cyst. LTGDC is frequently associated with respiratory problem in infants and pharyngeal foreign body sensation or dysphagia in adults. Because of its location and characteristics, lingual thyroid, dermoid cyst, and vallecular cyst should be included in differential diagnosis. Standard treatment for thyroglossal duct cyst is sistrunk's operation, but in terms of LTGDC, because of its location and cosmetic reasons, different kinds of treatments such as electrical cauterization, $CO_2$ laser, Robort surgery via transoral approach have been introduced. Recently authors encountered 21 years old woman with LTGDC and the mass was removed successfully via transoral approach using $CO_2$ laser. We report the clinical course with review of the literature.

  • 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.

  • Congenital thyroid dysgenesis including agenesis, hypoplasia and ectopia is the predominant cause of permanent hypothyroidism. Of these, two thirds are due to an ectopic thyroid and about one third to complete thyroid agensis. From Jan. 1981 to Dec. 1992, authors experienced the 9 cases of congenital thyroid dysgenesis. Aberrent thyroid was 4 cases (44.4%), thyroid hemiagenesis with aberrent thyroid was 3 cases(33.3%) and thyroid hemiagenesis was 2 cases(22.2%). The most predominant site of aberrent thyroid is the base of tongue(85.7%). 7 patients(77.8%) revealed euthyroidism and among them, 4 patients showed elevated TSH level. Hypothyroidism was 2 patients (22.2%). 7 cases responded to thyroid suppressive therapy. 2 cases of lingual thyroid which did not responed to thyroid suppressive therapy underwent surgery and they have placed on thyroid suppressive therapy postoperatively.

  • Purpose : To determine the optimal radiation dose in a localized non-Hodgkin's lymphoma of the head and neck in the treatment setting for combined chemoradiotherapy. Materials an Methods :Fifty-three patients with stage I and II diffuse large ceil non-Hodgkin's lymphoma of the head and neck, who were treated with combined chemoradiotherapy between 1985 and 1998 were retrospectively reviewed. The median age was 49 years, and the male-to-female ratio was approximately 1.6. Twenty-seven patients had stage 1 disease and 26 had stage II. Twenty-three patients had bulky tumors $(\geq5\;cm)$ and 30 had non-bulky tumors (<5 cm). The primary tumors arose mainly from an extranodal organ $(70\%)$, most cases involving Waldeyer's ring $(90\%)$. All patients except one were initially treated with $3\~6$ cycles of chemotherapy, which was followed by radiotherapy. Radiation was delivered either to the primary tumor area alone $(9\%)$ or to the primary tumor area plus the bilateral neck nodes $(91\%)$ with a minimum dose of 30 Gy $(range\;30\~60\;Gy)$. The failure patterns according to the radiation field were analyzed, and the relationship between the dose and the in-field recurrence was evaluated. Results : The 10-year overall survival and the 10-year disease free survival rates were similar at $75\%\;and\;76\%$, respectively. A complete response (CR) after chemotherapy was achieved in 44 patients $(83\%)$. Subsequent radiotherapy showed a CR in all patients. Twelve patients $(23\%)$ had a relapse of the lymphoma after the initial treatment. Two of these patients had a recurrence inside the radiation field. No clear dose response relationship was observed and no significant prognostic factors for the in-field recurrences were identified because of the small number of in-field recurrences. However, for patients with tumors <5 cm in diameter, there were no in-field recurrences after a radiation dose 30 Gy. The 2 in-field recurrences encountered occurred in patients with a tumor $\geq5\;cm$. Conclusion .A dose of 30 Gy is sufficient for local control in patients with a non-bulky (<5 cm), localized, diffuse large cell non-Hodgkin's lymphoma when combined with chemotherapy. An additional boost dose in the primary site is recommended for patients with bulky tumors $(\geq5\;cm)$.

  • Purpose : A retrospective analysis for patients with oropharyngeal carcinoma who were treated with radiation was performed to assess the results of treatment and patterns of failure, and to identify the factors that might influence survival. materials and methods : From March 1985 through June 1993, 53 patients with oropharyngeal carcinoma were treated with either radiation therapy alone or combination of neoadjuvant chemotherapy and radiation therapy at the Department of Radiation Oncology, Kyungpook National University Hospital. Patients' ages ranged from 31 to 73 years with a median age of 54 years. There were 47 men and 6 women, Forty-two Patients ($79.2\%$) had squamous cell carcinoma, 10 patients ($18.9\%$) had undifferentiated carcinoma and 1 patient ($19\%$) had adenoid cystic carcinoma. There were 2 patients with stage I, 12 patients with stage II, 12 Patients with stage III and 27 patients with stage IV. According to the TNM classification, patients were distributed as follows: T1 7, T2 28, T3 10, T4 7, TX 1, and N0 17, Nl 13, N2 21, N3 2. The primary tumor sites were tonsillar region in 36 patients ($67.9\%$), base of the tongue in 12 patients ($22.6\%$), and soft palate in 5 patients ($9.4\%$). Twenty-five patients were treated with radiation therapy alone and twenty-eight Patients were treated with one to three courses of chemotherapy followed by radiation therapy. Chemotherapeutic regimens used were either CF (cisplatin and 5-fluorouracil) or CVB (cisplatin, vincristine and bleomycin). Radiation therapy was delivered 180-200 cGy daily, five times a week using 6 MV X-ray with or without 8-10 MeV electron beams A tumor dose ranged from 4500 cGy to 7740 cGy with a median dose of 7100 cGy. The follow-up time ranged from 4 months to 99 months with a median of 21 months. Results : Thirty-seven patients ($69.8\%$) achieved a CR (complete response) and PR (partial response) in 16 patients ($30.2\%$) after radiation therapy. The overall survival rates were $47\%$ at 2 years and $42\%$ at 3 years, respectively. The median survival time was 23 months. Overall stage (p=0.02) and response to radiation therapy (p=0.004) were significant prognostic factors for overall survival. The 2-year disease-free survival rate was $45.5\%$. T-stage (p=0.03), N-stage (p=0.04) and overall stage (P=0.04) were significant prognostic factors for disease-free survival. Age, sex, histology, primary site of the tumor, radiation dose, combination of chemotherapy were not significantly associated with disease-free survival. Among evaluable 32 Patients with CR to radiation therapy, 12 patients were considered to have failed Among these, 8 patients failed locoregionally and 4 Patients failed distantly. Conclusion : T-stage, N-stage and overall stage were significant prognostic factors for disease-free survival in the treatment of oropharyngeal cancer Since locoregional failure was the predominant pattern of relapse, potential methods to improve locoregional control with radiation therapy should be attempted. More controlled clinical, trials should be completed before acceptance of chemotherapy as a part of treatment of oropharyngeal carcinoma.
