The authors present a case of 68-year-old woman who underwent resection of a metastatic adenocarcinoma in the left parietooccipital area. The intraoperative course was uneventful; however, after closure of the scalp incision, increased bleeding from the suture line was noted. A computerized tomography scan that was performed immediately after operation revealed acute epidural hemorrhage with mass effect under the bone flap. The patient developed disseminated intravascular coagulation and immediate re-exploration was performed. This patient was successfully treated owing to early recognition of the condition and immediate treatment with transfusion. Neurosurgeons should be alert that hypercoagulabe state is common in cancer patients and consumptive coagulopathy can occur after resection of metastatic brain tumor.

진행성 골화성 섬유이형성증은 매우 드문 유전적 질환이기는 하나 영유아 초기에 경부나 두부의 종괴에 동반하여 나타나는 특징적인 양측성의 족부 모지의 선천성 기형으로 진단이 가능하다. 그러나 오진으로 인한 잘못된 치료와 그로 인한 합병증이 병의 진행을 더 악화시킬 수 있으며 불필요한 처치를 행할 수 있어 처음 진단에 주의를 요하는 질환이다. 이에 저자는 이질환의 자연적 경과와 더불어 잘못된 치료로 인해 발생한 성인에서의 양상을 보고하는 바이다.

Although meningioma is a common and benign intracranial tumor, meningioma en plaque is a rare tumor, especially in the cranial vault. Meningioma en plaque[MEP] usually occurs in the area of the sphenoid wing, and it causes cosmetic and visual problems, as well as the problems that are due to its mass effect. The authors present here a case of convexity meningioma en plaque that involved the skull and scalp with diffuse hyperostosis as the presenting salient radiological findings, which caused marked intraoperative bleeding.

증식성 모낭 종양은 모낭 말단부위의 외근모초에서 기원하는 드문 종양이다. 악성 변화는 드물지만 갑작스러운 크기의 증가, 침윤성 성장 및 두피 이외에서 종양의 발생 등은 악성 증식성 모낭 종양을 시사한다. 병리조직학적으로 핵의 이형성, 다형성 및 유사분열 소견은 악성증식성 모낭 종양의 특징이다. 악성 증식성 모낭 종양은 재발 및 전이가 보고되고 있어 정상조직을 포함한 충분한 절제와 추적관찰이 요구된다. 53세 남자 환자의 우측 제 5수지 원위 지골에 7년전 발생한 종양을 중위 지이하 절제술 후 병리조직검사상 악성 증식성 모낭 종양으로 진단되었고, 환자가 외래로 더 이상 방문하지 않아 재발과 전이를 확인할 수 없었다.

Lipoblastoma is a rare benign soft tissue tumor occurring in infancy and early childhood. It is characterized by fat lobules with varying degrees of maturity, multivaculoated lipoblasts, fibrocapillary networks and myxoid stroma. Lipoblastoma has a good prognosis with no metastases despite its potential for local invasion. From Jan, 1990 through April, 2007, 12 children underwent the operation for lipoblastoma, 7 boys and 5 girls, diagnosed at median 22 months (5 ~ 43 months). Median follow up was 6 year 7 months. Primary sites included back (n = 5), intraabdominal (n = 2) and one in each of buttock, chest wall, neck, nose and scalp. Tumors presented with a growing mass in 9 patients, abdominal distension in 2, and an incidental finding on chest radiography in one. Complete excisions were done in all patients. There was one recurrence in a patient with a scalp mass. After reoperation, he has been doing well without evidence of recurrence. Lipoblastoma has a favorable prognosis, but recurrence can occur even with complete excision. Regular follow up is necessary to detect recurrences.

Treatment for the brain tumors consist of surgery, chemotherapy, and a variety of methods of irradiation. Therapy is aimed to destroy the tumor, but necrosis and edema occur concurrently. Conventional structural imaging techniques such as CT or MRI are unable to reliably distinguish persistent and recurrent tumor from necrosis or edema. T1-201 has been shown to be useful in the evaluation of the myocardial viability by comparing the early uptake and redistribution image. The aim of this study is to evaluate the clinical usefulness of the early uptake and delayed washout images of the T1-201 brain SPECT in the brain tumors. In the pathologically diagnosed various brain tumor patients, brain SPECT was done with rotating gamma camera 15 minutes and 3 hours after T1-201 injection, and the T1-201 uptake in the tumor was compared with the skull and scalp activity. In the glioblastoma multiforme, meningioma and metastatic tumor, the T1-201 uptake was higher than low grade glioma in both 15 minute and 3 hour images (p<0.02). In the low grade glioma,3 hour T1-201 uptake was significantly lower than 15 minute uptake (p<0.05) but in the glioblastoma, meningioma and metastatic tumor there was no significant difference. There was no significant difference in the T1-201 uptake among the glioblastoma, meningioma and metastatic tumors. In one matastatic tumor, T1-201 uptake was decreased after radiation therapy. T1-201 brain SPECT could distinguish the benign and malignancy, and seems to be useful in the follow-up after treatment. But one of the early or delayed SPECT seems not to be necessary for these purposes.

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.

Skin replacement in large cheek defects after excision of benign or malignant tumor on the face is a challenging task. The physical characteristics of cheek skin are matched best by adjacent skin. Various methods of reconstructing of the facial surface such as forehead flap, distant flap, or a full thickness or split thickness skin graft have replaced adjacent tissue for coverage in many cases. We have reviewed ten cases of aesthetic reconstruction of the face after resection of the facial skin tumor within the last 5 years. The first group of 3 patients were reconstructed with split thickness skin graft from the scalp or lower abdomen. The second group of patients were reconstructed with cheek flap. The third group of 3 patients were reconstructed with cervicofacial flap. The last 2 patients were reconstructed with nasolabial flap & island falp respectively. The advantages from our experience with various method of coverage are its hidden donor area & good color match with the facial skin & increased success rate.

Mucinous Eccrine carcinoma (MEC) is a rare malignant tumor related to the eccrine sweat gland and is commonly located on the face, especially around the eyelids and scalp. Most of these tumors are diagnosed at age 40's to 60's and exhibit a wide variety of patterns in addition to the general appearance previously reported. MEC is difficult to diagnose clinically, but can be diagnosed by accompanying biopsy. We present the case of a 75-year-old man who complained of a gradually growing Left lower lid tumor of duration one year. Initially, the tumor was mistaken for an epidermal cyst and treated by surgical resection. However, biopsy findings resulted in a diagnosis of Mucinous Eccrine carcinoma. Therefore, we performed wide excision and flap reconstruction surgery. In a one year follow-up examination, the patient achieved successful functional and aesthetic results without regional or distant metastasis and recurrence.

Introduction: Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare cutaneous tumor of low grade malignancy and microscopically resembles lymphoepitheliomatous malignancies in the nasopharynx, palatine tonsils, salivary glands and uterine cervix. LELCS presents as scarlet-colored firm nodules or plaques on the face, scalp, or shoulder of middle-aged to elderly individuals. Material and Methods: A 72 year-old female had complained a papule like lesion with intermittent pruritis on the left temple for 2 years. But the lesion was changed to scarlet-colored firm nodule with ulceration. The mass was diagnosed as LELCS on the biopsy. And to confirm that the mass is not metastatic lymphoepithelioma-like carcinoma from other sites or direct tumor extension from the nasopharynx, selective radiographic and laboratory tests were done carefully. Results: Wide excision was performed with general endotracheal anesthesia. The tumor is composed of island of large epithelial cells surrounded by as dense infiltrate of lymphocytes. Immunohistochemical staining with cytokeratin and epithelial membrane antigen(EMA), the tumor cells were positive reaction for stain. And Epstein-Barr virus genome was not detected by in situ hybridization. So, the tumor was confirmed as LELCS. Conclusion: LELCS was described by Swanson at 1988, but has not been reported in the field of plastic surgery of Korea. We report a case of primary LELCS that occurred in the left temple with clinical characteristics, histologic features and references.
