흉폐부 또는 흉벽에서 발생하는 악성소세포 종양군인 Ewings sarcoma, 횡문근육종, Askin tumor, 신경아세포종, PNET, 임파종 등은 현미경학적 소견만으로는 감별하기 어렵다. 그러나 최근에는 조직세포화학적검사, 면역세포화학적검사, 세포배양, 세포유전학적 검사등의 도움으로 상기한 악성소세포 종양군들이 모두가 같은 계통의 primitive pluripotent cells로 부터 분화되어 발병되는 것으로 확인되었다. 치료는 외과적 절제술, 방사선치료, 항암요법 등이 시도되고 있으나 예후는 재발 과원격전이로 인하여 불량한 것으로 보고되고 있다. 본 저자들은 본원에서 치료한 예를 보고하면서 흉폐부에서 발생하는 악성소세포 종양군의 조직발생과 감별진단에 대하여 논하고자 한다.

동면선종(hibernoma)은 갈색지방조직에서 발생한 양성종양이다. 겨울잠을 자는 동물의 갈색지방조직이 총선과 유사한 내분비기관으로 간주되어 동면선종으로 알려졌었고 이러한 갈색지방은 동면하지 않는 동물에서도 발견되며 사람에서도 태아와 신생아기에 주로 존재하다가 점 차 황색지방으로 대치되는데 그 기능은 확실하지 않다. 1914년 Gery에 의해 명명된 동면선종은 3∼19cm정도의 크기로 아직까지 악성전환은 보고되지 않았고 피막형성이 잘되어 전적출술로서 완치가 가능하지만 수술시 남겨진 조직에서 재발된 경우는 보고되어 있다. 종양의 호발부위는 견갑간부,목뒤쪽,종격동,후복벽 등이며 흉곽내 발생은 7례에 불과하다. 조직학적 소견은 과립상 호산구성 세포질을 가지면서 여러개의 공포를 가진 세포들이 혼재해 있는 것이 특징으로 되어있다. 저자들은 좌측 후하부 흉벽과 복벽에 걸쳐 있는 동면선종을 경험하여 보고 하는 바이다.

Accessory cervical thymic tissue has been rarely reported. However, it should be included in the differential diagnosis of neck masses in children, along with branchial anomalies, lymph nodes and other tumors. This lesion occurs along the descending line of the thymus between the angle of mandible and superior mediastinum. A 2-month-old infant presented with an asymptomatic left sided neck mass. MRI revealed a well defined homogeneous mass in the deep lobe of left parotid gland. At operation, an easily identified soft tissue mass was found in the left submandibular area, measuring $3{\times}1.5cm$. It was completely excised. Microscopic examination revealed normal thymic tissue.

Background The chest wall defects can be caused by various reasons. In the case of malignant tumor resection of the chest wall, it is essential to reconstruct the chest wall to cover the vital tissue and restore the pulmonary function with prevention of paradoxical motion. With our experience, we analyzed and evaluated the results and complications of the chest wall reconstructions followed by malignant tumor resection. Methods From 2013 to 2022, we reviewed a medical record of patients who received chest reconstruction due to chest wall malignant tumor resection. The following data were retrieved: patients' demographic data, tumor type, type of operation, method of chest wall reconstruction of the soft and skeletal tissue and complications. Results There were seven males and six female patients. The causes of reconstruction were 12 primary tumors and one metastatic carcinoma. The pathological types were seven sarcomas, three invasive breast carcinoma, and three squamous cell carcinomas. The skeletal reconstruction was performed in six patients. The series of the flap were eight pedicled latissimus dorsi (LD) myocutaneous flaps, two pectoralis major myocutaneous flap, two vertical rectus abdominis myocutaneous free flap, and one LD free flap. Among all the cases, only one staged reconstruction and successful reconstruction without flail chest. Most of the complications were atelectasis. Conclusion In the case of accompanying multiple ribs and sternal defect, skeletal reconstruction would need skeletal reconstruction to prevent paradoxical chest wall motion. The flap for soft tissue defect be selected according to defect size and location of chest wall. With our experience, we recommend the reconstruction algorithm for chest wall defect due to malignant tumor resection.

구강내에 발생하는 암종은 원발성으로 나타나는 것이 보통이지만 신체내 다른 부위의 원발성 암종에 의해 이차적으로 전이되기도 한다. Clausen 과 Poulsen에 의하면 원발성 암종중에서 breast, lung, kidney, thyroid의 순으로 구강내 전이암종을 많이 나타내는 것으로 알려져 있다. 문헌에 의하면 구강 및 악골에 발생한 전이암종 중에서 약 70%가 adenocarcinoma 이며 주로 혈행적(hematogenous) 전이를 하는 것으로 알려져 있다. 이때 전이는 일차적으로 악골내에, 이차적으로 연조직에 전이되며, 이로인해 발생한 악성 전이 암종은 구강내에 발생하는 악성종양의 약 1%에 해당한다. 그러나, 실제로 이의 발견이 어려운 것은 악골에 대한 일상의 검사가 이루어지지 않으며 환자 자신이 특별한 증상을 호소하지 않기 때문이다. 본 교실에서는 문헌상 빈도수가 적은 gall bladder cancer 와 pancreatic tumor 에서 전이된 암종이 특이하게 악골내에서는 나타나지 않고 연조직에만 발생하였기에 이에 보고하는 바이다.

Tumors of the central nervous system are common in the pediatric population and constitute the second most prevalent tumor type in children. Within this group, spinal cord tumors are relatively rare and account for 1 to 10% of all pediatric central nervous system tumors. We describe a very rare case of an intradural extramedullary spinal cord tumor with a subcutaneous mass and discuss its clinical presentation, pathogenesis, and treatment. A male infant was delivered normally, with uneventful development. At 16 days post-delivery, his family took him to a pediatrician because of a mass on his upper back. Magnetic resonance imaging of the thoracic spine revealed a well-demarcated soft-tissue mass with central cystic change or necrosis at the subcutaneous layer of the posterior back (T2-7 level). Another mass was found with a fat component at the spinal canal of the T1-3 level, which was intradural extramedullary space. After six weeks, the spinal cord tumor and subcutaneous mass were grossly total resected; pathologic findings indicated an atypical myxoid spindle cell neoplasm, possibly nerve sheath in type. The final diagnosis of the mass was an atypical myxoid spindle cell neoplasm. The postoperative course was uneventful, and the patient was discharged after nine days without any neurological deficit. We report a rare case of an intradural extramedullary spinal tumor with subcutaneous mass in a neonate. It is necessary to monitor the patient's status by examining consecutive radiologic images, and the symptoms and neurological changes should be observed strictly during long-term follow-up.

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.

Desmoid tumors are rare soft tissue tumors considered to have locally infiltrative features without distant metastasis until now. Although they are most commonly intraabdominal, very few cases have extra-abdominal locations. The origin of intrathoracic desmoid tumors is predominantly the chest wall with occasional involvement of pleura. True intrathoracic primary desmoid tumors with no involvement of the chest wall or pleura are extremely rare. We recently experienced a case of true intrathoracic desmoid tumor presenting as multiple lung nodules at 13 years after resection of a previous intraabdominal desmoid tumor.

1979년 1월부터 1996년 8월까지 전북대학교병원 흉부외과에서 치료한 원발성 흉벽종양은 51례이다. 원발성 종양을 가진 환자의 평균 나이는 36.1세이고 남자는 32명, 여자는 19명이었다. 양성종양이 40례(78.4%), 악성종양이 11례(21.6%)이었다. 증상은 국소 종괴가 가장 흔한 증상으로 32(62.7%)례에서 있었다. 골 및 연골 조직에서 발생한 경우는 32례(62.7%), 연부조직에서 발생한 경우는 19례(37.3%)이다. 양성 종양인 경우 3례에서는 광범위 절제술 및 흉벽 재건술이 시행되었고 37례에서는 절제술만 시행되었으며 현재까지 재발이나 종양관련 사망은 관찰되지 않았다. 악성 종양인 경우 광범위 절제술 및 재건술을 시행한 경우는 8례에서 시행되었다. 광범위 절제술이 시행된 5례에서는 Marlex Mesh, Prolene Mesh와 Teflon felt을 이용하여 흉벽 재건술이 시행되었다. 전 예에서 수술과 관련된 사망은 없었다. 광범위 절제술을 받은 악성종양 환자 중 5례(71.4%)가 생존하고 있다.

사구종 환자 8례중 단순 절제만으로 전례에서 동통 소실과 함께 종괴 제거 후 세심한 조상 봉합을 함으로써 손톱의 변형을 최소화 할 수 있었고, 수술시 손톱을 완전히 제거하지 않고 다시 제 위치에 고정함으로써 수술후 창상치료가 간편하였으며, 환자가 조기에 손가락을 사용하는데 불편함을 최소화 할 수 있었다.
