  • 신경섬유종증(neurofibromatosis)은 골조직, 신경계, 연부조직, 피부 및 내분비계 장애를 수반하며 상염색체 우성을 보이는 유전질환으로 제17번 염색체의 장완에 위치한 종양 억제 유전자의 변성에 의해 발생한다. 임상적으로 진단에 도움을 주는 특정적인 소견들 중 가장 중요한 것은 신경섬유종(neurofibroma)이고 그 외에 밀크 커피색을 띠는 밀크 커피색 반점(cafe-au-lait spot)과, 홍채결절(Lisch nodule)이 있다. 신경섬유종증이 비교적 구강 내에서 발현하는 비율은 비교적 낮은 것으로 알려져 있고, 대부분의 경우 단독 혹은 다수의 신경섬유종이 존재하는 연조직 변화와 관련되어 있다. 최근 전북대학교 병원에서 제1 형 신경섬유종증으로 진단받고, 치아우식증 치료를 위해 본원 소아치과에 내원한 만 4세의 남아와 그의 아버지에게서 제1형 선경섬유종증의 특징적인 치과적 소견을 발견하였기에 치료 경과와 함께 보고하는 바이다.

  • A rare case of gliosarcoma with neurofibromatosis type I is presented. The patient was a 33-year-old woman who had headache and vomiting for one week. Multiple neurofibromas over her whole body with many cafeau- lait spots were present since childhood. At admission, she had no focal neurological deficit and ophthalmologic examination revealed bilateral Lisch nodules. Brain CT and MRI revealed a heterogeneously enhancing mass in the left fronto-parietal region with marked peritumoral edema and mass effect. The tumor was removed gross totally and a gliosarcoma was diagnosed histopathologically. Post operative course was uneventful with resolution of symptom, followed by radiotherapy with 60 Gy. A brief overview is given of this rare case together with the pertinent literature.

  • Von Recklinghausen병에 동반되는 악성종양은 주로 신경섬유육종이지만 드물게는 폐암이 동반되는 경우가 보고되고 있고 ras 유전자가 양 질환의 발생에 영향이 있음이 알려져 있어 앞으로 이에 관한 연구가 필요하리라 생각된다.

  • 신경섬유종증 1형은 비교적 흔한 유전 질환이며 신경섬유종 형성, 피부의 색소 이상, 홍채의 리쉬결절 및 골격 이상들을 특징으로 한다. 다발성 피부 신경섬유종은 양성 신경초 종양이며 신경섬유종증 1형의 특징적인 병변이다. 신경섬유종증 1형과 관련된 심장 신경섬유종은 매우 드물며 문헌에 몇 가지 사례가 보고되었다. 이에 저자들은 신경섬유종증 1형을 가진 32세 여성에서 수술로 확진된 좌심실 신경섬유종의 컴퓨터단층촬영 및 자기공명영상 소견을 보고한다.

  • Type 1 neurofibromatosis (von Recklinghausen's disease, NF-1) is an autosomal-dominant neurocutaneous-disorder characterized by systemic cafe'-au-lait spots, multiple cutaneous neurofibromas, axillary or inguinal freckling, and Lisch nodules (pigmented iris hamartomas). Approximately 10-25% of NF1 patients have gastrointestinal neoplasms. Gastrointestinal stromal tumor (GIST) in patients with neurofibromatosis is most commonly found in the small bowel and the stomach, and approximately 60% of such patients have multiple tumors or multiple tumor sites. Although, the increased incidence of GIST in patients with neurofibromatosis is well documented in pathology literature in English, but has rarely been documented in Korea. Here, we report a case of multiple GISTs in a 48-year-old woman accompanied by NF1. She was admitted to Yeung-nam University Hospital with complaints of melena and dyspnea. A contrast-enhanced computed tomography (CT) scan revealed that multiple soft tissue masses were occupying the entire peritoneal cavity. An ultrasonogram- guided biopsy was performed and the tumors were found to have been composed of tumor cells that were positive for c-kit protein. The patient was put on Imatinib mesylate treatment, and further follow-up will be carried out.

  • Purpose: Neurofibromatosis 1 (NF1) is an autosomal dominant condition caused by an NF1 gene mutation. NF1 is also a multisystem disorder that primarily affects the skin and nervous system. The goal of this study was to delineate the phenotypic characterization and assess the NF1 mutational spectrum in patients with NF1. Methods: A total of 42 patients, 14 females and 28 males, were enrolled in this study. Clinical manifestations and results of the genetic study were retrospectively reviewed. Results: Age of the patients at the time of NF1 diagnosis was $15.8{\pm}14.6$ years (range, 1-62 years). Twelve patients (28.6%) had a family history of NF1. Among the 42 patients, $Caf\acute{e}$-au-lait spots were shown in 42 (100%), neurofibroma in 31 (73.8%), freckling in 22 (52.4%), and Lisch nodules in seven (16.7%). The most common abnormal finding in the brain was hamartoma (20%). Mental retardation was observed in five patients (11.9%), seizures in one patient (2.4%), and plexiform neurofibromas (PNFs) in four patients (9.5%). One patient with PNFs died due to a malignant peripheral nerve sheath tumor in the chest cavity. Genetic analysis of seven patients identified six single base substitutions (three missense and three nonsense) and one small deletion. Among these mutations, five (71.4%) were novel (two missense mutations: p.Leu1773Pro, p.His1170Leu; two nonsense mutations: $p.Arg2517^*$, $p.Cys2371^*$; one small deletion: $p.Leu1944Phefs^*6$). Conclusion: The clinical characteristics of 42 Korean patients with NF1 were extremely variable and the mutations of the NF1 gene were genetically heterogeneous with a high mutation-detection rate.
