Sinonasal Undifferentiated Carcinoma (SNUC) is a very rare, highly aggressive malignant tumor of the nasal cavity and paranasal sinuses. SNUC tends to present with advanced-stage disease, often with intracranial invasion. It requires an aggressive multimodality therapy that includes surgical resection. A cure rate of less than 20% is generally reported in the literature, with most patients dying within 1 year of onset of the disease. Three patients diagnosed as SNUC were treated at the Yeungnam University Medical Center between the years 2000 and 2003 were analyzed retrospectively. All patients presented with the disease very advanced. The three cases were given chemotherapy or chemotherapy with radiotherapy. Two patients died of the disease, surviving only 6 and 11 months following treatment, respectively. We did a follow-up on just the one remaining case with incomplete controlled disease for 27 months. The overall prognosis of SNUC is very poor. We consider that more intensive multimodality therapies are recommended for all patients with SNUC.

Skull base osteoradionecrosis(ORN)is a rare complication of radiotherapy for nasopharyngeal carcinoma, but is one of the most severe and possibly fatal condition followed by radiotherapy. However, the treatment of skull base ORN has seldom been thoroughly described yet. Here we report a case of skull base ORN that was successfully treated with hyperbaric oxygen therapy(HBO). A 52-year-old man visited our department complaining of trismus and foul odor. He was diagnosed with nasopharyngeal cancer with multiple lymph node metastasis one year ago and underwent concurrent chemoradiotherapy. On the physical examination, mucopus and crusts with exposed necrotic bone was seen in the right nasopharynx. On the paranasal sinus magnetic resonance imaging, osteoradionecrosis which was extending from the right nasopharynx to the clivus, petrous apex, and cavernous sinus was noted. Nasopharynx biopsy resulted of ulcer with no malignant cells. HBO therapy was performed with debridement of nasopharynx for 3 months. There was no sign of recurrence or residual ORN 18 months after HBO therapy.

비강 및 부비동의 점막에서 발생하는 양성상피종양인 반전성 유두종은 비교적 드물며 1854년 Ward에 의해 처음으로 기술된 이래 여러 학자들에 의해 본증이 논의되어 왔으나 한국에서는 그 보고례가 매우 드물었다. 병리조직학적으로 양성인 이 종양은 비강이나 골 및 주위조직의 파괴성 병변이 빈번하고 수술 후 재발이 잘되고 드물게 악성으로 변하는 성질을 나타내므로 임상적으로 악성으로 알려져 왔다. 일단 반전성 유두종으로 확진되게 되면 가능한 한 광범위한 절제가 필요하며 술 후에도 계속적이 추적조사가 필요하다고 하겠다. 최근 저자들은 비폐색, 종류감을 주소로하여 내원한 48세된 남자환자에서 우측비강, 상악동에서 발생하여 국소적으로 악성화 변화를 일으킨 반전성 유두종 1례를 비내 및 Caldwell＿LUC식 방법으로 절제후 Bleomycin 정맥주사, 5＿FU 국소분무요법 및 방사선요법($Co^{60}$)을 병용하여 좋은 결과를 얻었기에 이를 문헌적 고찰과 함께 보고하는 바이다.

This type of neuropathic pain(atypical odontalgia) is seen most often in middle-aged women or men after dentoalveolar operation. Atypical odontalgia probably is caused by deafferentation leading to intraneural changes in the medullary dorsal horn. Treatment of this problem is difficult, but some success has been reported in uncontrolled, open-labeled studies using high doses of tricyclic antidepressants. This is the management report of a patient case, that had a neuropathic atypical odontalgia recognized with the right maxillary lateral incisor. The patient was consulted to the Department of Pain Clinics, ENT & Neurology and diagnosed the adenoid cystic carcinoma on left cerebellum and right paranasal sinus with extension to the cavernous sinus. In spite of the osteoplastic craniotomy, neurosurgical mass removal and radiation therapy were done with chemotherapy, atypical odontalgia was continued. In addition to the consultation to Psychology, stress management and antidepressant medication were done and improved slowly.

Background: Inverted papilloma(IP) of the nasal cavity and paranasal sinuses is a benign neoplastic condition that can be associated with squamous cell carcinoma (SCC). Several studies have indicated an etiologic role for viruses in the development of inverted papilloma. And it is necessary to find out the significance of a biologic markers such as p53, c-erbB-2 to predict the malignant potential. The purposes of this study are to detect HPV in inverted papilloma of the nasal cavity and paranasal sinus, to examine role of HPV as an etiological agent, to examine the relationship between HPV subtype and malignant transformation of inverted papilloma, and to investigate the relation between expression rate of p53, c-erbB-2 and HPV in recurrent or malignant transformation cases. Material and Methods: Thirty two cases of inverted papilloma(IP) in the nasal cavity and paranasal sinuses were reviewed and classified into 3 groups; simple IP, IP with dysplasia group, IP with squamous cell carcinoma group. Paraffin embedded achival tissue was used in this study. The HPV was detected by in situ hybridzation (ISH) using HPV type 6/11, 16/18, 31/33/35 DNA probes. Expression of p53 and c-erbB-2 was examined by immunohistochemical staining. Results: 1) The HPV was detected in 6(19%) out of 32 cases. 2) The HPV 6/11 was dectected in 4 out of 21 cases of simple IP, HPV 16/18 in 1, HPV 31/33/35 in lout of 8 cases of IP with dysplasia respectively. 3) The positive expression of p53 was 13 cases out of 32 cases; 2 out of 21 cases of simple IP, all of 8 cases of IP with dysplasia and 3 cases of IP with squamous cell carcinoma 4) The positive expression of c-erbB-2 was in 24 out of 32 cases; 16 out of 21 cases of simple IP, 6 out of 8 cases of IP with dysplasia, 2 out of 3 cases of IP with squamous cell ca. 5) The recurrence of IP occurred in lout of 6 cases of positive for HPV, in 4 out of 26 cases negative for HPV. 6) The recurrence of IP occurred only in positive cases for p53. 7) The recurrence of IP occurred in 4(17%) out of 24 cases positive for c-erbB-2, in 1(13%) out of 8 cases negative for c-erbB-2. Conclusion: The p53 expression was associated with Inverted papillomas exhibiting evidence of malignant transformation. Also, there was a correlation between the p53 expression and recurrence.

Background and Objectives: Minor salivary gland tumors vary in their primary sites, histopathology and biological behavior. Therefore, various factors are considered in selecting the treatment modality and predicting the prognosis. We performed this study for the purpose of getting further understanding and more supporting ideas for the diagnosis and treatment of minor salivary gland tumor. Materials and Methods: A retrospective analysis of the patients with 52 cases of minor salivary gland tumor who were treated at the Hanyang University Hospital from 1996 to 2003 was performed. We analyzed demography, symptoms, histopathology, treatment and outcomes by the review of medical records. Results: Among 52 cases of minor salivary gland tumor, 46% were classified as benign and 54% were classified as malignant tumors. The most common benign tumor was pleomorphic adenoma. Adenoid cystic carcinoma(15/28) was the most common in malignant tumors. Eight patients were males and sixteen patients were females in benign tumors and 10 patients were males and 18 patients were females in malignant tumors. The most common site of benign tumor was the palate(17/22), whereas malignant tumors were most common in the nasal cavity and paranasal sinus(9/28). Asymptomatic mass was the most common symptom. According to the criteria given by the AJCC on staging, stage III and IV(21/28) were more common than stage I and 11(7/28). All benign tumors were treated with simple excision and had no recurrence. In malignant tumors, 25 patients underwent radical excisional operation and 13 patients of them had postoperative radiation therapy. Three of them were treated with additional chemotherapy. In whom treated with radical operation, 9 patients had recurrence. Three were recurred at the primary site with neck node metastasis, 3 were recurred at the primary site with lung metastasis, 1 was recurred at the primary site with neck node and lung metastasis, 1 was recurred only at neck node. Conclusion: In minor salivary gland tumor, malignant was more common than benign. Malignant tumor originated from minor salivary gland were more frequently diagnosed at advanced stage with high recurrence rate and distant metastasis. Early detection of the disease is needed to improve the prognosis of the patients with malignant tumors of the minor salivary glands.
