CT findings of proven 25 malignant tumors of the maxillary sinus were retrospectively analyzed to be of help in the diagnosis and treatment. The results were follows: 1. Average age was 54 years old, and eighteen were males and seven were females with a ratio of 2.6:1 2. The most common histopathologic feature was squamous cell carcinoma (19 cases) and others were two cases of adenoid cystic carcinoma, one case of malignant fibrous histiocytoma, mucoepidermoid tumor, histiocytic lymphoma, unidentified malignant tumor. 3. CT findings were sinus opacificaqtion (4%), soft tissue mass (92%), low densities within soft tissue mass (44.%), air densities within soft tissue mass (24%), osteosclerosis (4%), bone destruction (92%), bone displacement (32%), fat plane obliteration (76%). 4. CT in the malignant maxillary sinus tumors approved the value in evaluation of tumor extension to nasal cavity, ethmoid sinus, orbit, infratemporal fossa, pterygopalatine fossa, pterygoid fossa, pterygoid muscle, cheek skin and intracranial cavity. 5. Twenty four cases (96%) were stage Ⅲ, stage Ⅳ according to AJCC TNM classification. 6. Bone findings were destruction, displacement, sclerosis and most frequent site of bone destruction was the medial wall of the antrum(92%). 7. Tumor growth pattern showed destructive pattern in 18 cases(72%), and squamous cell carcinoma showed destructive pattern. (P<0.05)

Nasopharyngeal tuberculosis is a rare pathological condition. It is most often associated with lymph node and pulmonary lesions, but it may be an isolated lesion. The clinical manifestation may resemble a malignant tumor of the nasopharynx and the nasopharyngeal tuberculosis is occurred occasionally primary infection but more frequently secondary infection to pulmonary tuberculosis. The nasal endoscopic evaluation of nasopharynx is necessary in patient with possible pulmonary or extrapulmonary tuberculosis. The author reports two cases of nasopharyngeal tuberculosis in a 45-years old and 34-years old woman with a review of the literature.

Atypical fibroxanthoma(AFX) is a tumor that occurs as a solitary and ulcerative nodule on actinically damaged or radiation damaged skin of the head and neck in the elderly. AFX is a pleomorphic spindle cell neoplasm of the dermis, which is a clinically benign reactive lesion despite of apparently malignant histologic features. We report a case of AFX which developed on the nasal root area of a 23-year-old man. This case is very unusual in terms of site(less sun-damaged area), overlying skin feature(grossly normal skin) and age(too young). This tumor was completely removed with surgical excision and remained free of recurrence for a period of about 1 year follow-up.

The false-positive FDG uptakes on head and neck areas are common due to benign lesion, iatrogenic and physiologic changes. The Schneiderian papilloma is uncommon benign tumor arising from the mucosa of the paranasal sinuses and nasal cavity. The findings of paranasal papilloma on conventional modality such as CT and MRI are non-specific and they could be confused with inflammatory polyp or retention cyst. Despite of benign tumor, the papilloma usually shows locally aggressive growth with malignant potential, therefore the FDG can be actively accumulated in this lesion. We describe the case of 18F-FDG PET/CT finding in a 77-year-old woman who demonstrates oncocytic papilloma in maxillary sinus.

Malignant lymphoma is the tumor of immune system which is known as the most common nonepitheloid tumor of head and neck region. It is mainly found in the cervical, axillary and inguinal lymph node, but gastrointestinal tract, palatine tonsil, nasopharynx, oropharynx, nasal cavity and salivary glands may be involved. Primary lymphoma of the thyroid gland is an uncommon condition, comprising approximately 2% of all malignant lymphoma and 5% of all thyroid malignant neoplasms. Recently, we experienced a case of malignant lymphoma of the thyroid gland, which was histopathologically proven. So we report our findings in this patient with review of literatures.

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.

Sebaceous carcinoma is a malignant neoplasm that usually arises in the sebaceous glands of the eyelids. Its pathogenesis is unknown; however, irradiation history, immunosuppression, and use of diuretics are known risk factors. The mainstay of treatment for sebaceous carcinoma of the eyelid is wide surgical resection with a safety margin of 5 to 6 mm, which often results in full-thickness defects. The reconstruction of a full-thickness defect of the eyelid should be approached using a three-lamella method: a mucosal component replacing the conjunctiva, a cartilage component for the tarsal plate, and a flap or skin graft for the skin of the eyelid. In this case, a full-thickness defect of the upper eyelid was reconstructed after tumor removal using a combination of a nasal septum chondromucosal composite graft and a forehead transposition flap, also known as a "Fricke flap." The flap was designed to include a line of the eyebrow on the lower margin of the flap to replace the eyelash removed during tumor excision. The wound healed completely, without any early or late complications, and the outcome was satisfactory.

Ewing's sarcoma is an uncommon malignant neoplasm of the long bone and it has a poor prognosis due to its early metastasis and aggressive local spread. It is mostly found before the age of 30 and it is rare in extraskeletal sites. Extraskeletal Ewing's sarcoma has been reported to occur in various sites including the larynx, scalp, nasal fossa, neck, chest wall, lung, pelvis, perineum, arm, finger, leg and toe, but it is extremely rare as a primary epidural tumor of the spine. We experienced a case of extraosseous epidural Ewing's sarcoma arising in the lumbar spinal canal at L3-L5 level in a 9-year-old boy. Following total laminectomy from L3 to L5 with a lumbar vertebrae and mass excision, he received chemotherapy with complete remission.

Typical transcranial approaches are insufficient for adequate visualization and resection of skull base tumors. Different approaches with multiple modifications have been attempted. Here, we describe a new approach for a lesion that is central and hard to treat by conventional craniotomy and successful reconstruction with calvarial bone graft and titanium mesh plate. A 69-year-old female patient presented with recurrent meningioma. The tumor had invaded the frontal lobe, right supraorbital rim, and ethmoidal bone. We performed a modified anterior craniofacial approach that fully exposed the tumor and invaded bone. In consideration of the patient's age and cosmetic result, the tumor and invaded bone was resected and the defect area was reconstructed with titanium mesh and calvarial bone graft. At 6 months postoperative the patient had no complications and was satisfied with the esthetic result. We report this case to demonstrate the successful approach and reconstruction using this technique.

Hemangioma is a benign vascular tumor that grows by endothelial cell hyperplasia. It occurs most frequently in the head and neck region. Nose reconstruction is tricky because of its unique three-dimensional structure and different tissue components. We report a case of successful reconstruction of near-total nose defect using the paramedian forehead flap combined with a nasolabial flap, immediately after excision of nasal hemangioma. A 49-year-old male patient was presented with a huge mass at the nose. Preoperative magnetic resonance imaging showed prominent vascular channels extending to the forehead and cheek. Complete resection of the mass was performed, which resulted in an eccentric defect. The right paramedian forehead flap and the left nasolabial flap were designed and transferred to the defect. Flap division was performed 1 month later. The patient is satisfied with the overall appearance and did not develop any functional deficit.
