Ancient schwannoma is a rare variant of schwannoma and a slow growing benign tumor associated with degeneration that may be diagnosed as a malignant tumor, because it presents with a large size and an inhomogeneous signal intensity. The main differential diagnosis of plexiform soft tissue tumor includes plexiform neurofibroma, malignant peripheral nerve sheath tumor (MPNST). In this case, we describe the MRI findings in a case of ancient schwannoma involving left thigh of a 63-year-old woman mimicking a plexiform MPNST. The tumor appeared as an inhomogeneous signal intensity and multinodular appearance, causing misdiagnosis as a plexiform MPNST.

목적: 항암유발말초신경병증은 암 환자가 겪는 흔한 항암 부작용이나 현재까지 효과적으로 알려진 치료법은 없다. 본 연구의 목적은 항암유발말초신경병증에 대한 침 치료와 가바펜틴의 병용 요법의 효과와 안전성을 평가하는 것이다. 방법: 항암유발말초신경병증을 겪고 있는 24명의 암 환자를 침 치료 단독군 (AG, acupuncture group)과 침과 가바펜틴의 병용요법군 (CG, combined acupuncture and gabapentin group)으로 무작위 배정하였다. 두 그룹 모두 침 치료는 주 3회, 4주간 수행하였다. 병용 요법군은 침 치료와 더불어 1일 900mg의 가바펜틴을 복용하도록 하였다. 치료 효과는 Neuropathic Pain Symptom Inventory (NPSI), visual analogue scale (VAS), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20 items (EORTC-CIPN20)를 이용하여 측정하였다. 치료로 인한 부작용은 대상자가 방문할 때마다 조사하였다. 결과: 총 23명의 대상자(AG, n=12; CG, n=11)의 평가지표를 분석한 결과, 치료 4 주 후 침 치료 단독군은 NPSI 점수가 44.33±25.04에서 30.58±21.55으로 감소하였고, 병용 요법군은 30.55±25.59에서 18.64±19.42로 감소하였으며, 두 군 모두 통계적으로 유의미하게 감소하였다(p<0.001). VAS점수는 침 치료 단독군에서는 4.79±2.17 에서 3.42±2.49으로 감소하였고, 병용 요법군에서는 3.55±2.07에서 2.73±2.49 로 감소하였다(p<0.05). 치료 효과는 치료 완료 2주후까지 지속되었으며, 두 군간의 유의미한 차이는 없었다. EORTC-CIPN20은 침 치료 단독군은 30.27±18.87에서 20.84±16.35으로 감소하여(p<0.01), 두 군 모두에서 삶의 질이 향상되었다. 결론: 본 연구로 침 치료와 가바펜틴의 병용 요법이 항암유발말초신경병증 환자의 증상 및 삶의 질 개선에 효과적이며 안전한 치료법임을 확인하였다. 그러나 침 치료와 가바펜틴의 시너지 효과에 대해서는 확인 할 수 없었으며, 이를 확인하기 위해 추가적인 연구가 필요할 것으로 사료된다.

Primary masses rarely originate from the heart and great vessels, and a malignant peripheral nerve sheath tumor (MPNST) is extremely rare. A 76-year-old male with pleural effusion underwent contrast-enhanced computed tomography, which revealed a hypoattenuating mass involving the right pulmonary vein and left atrium. Ultrasonography showed that the mass originated from the right pulmonary vein. Surgical resection confirmed an MPNST that originated from the pulmonary vein. We report the first Korean case of a primary MPNST originating from the pulmonary vein. We have also described the radiologic findings suggestive of a pulmonary vein mass.

This journal reports three cases diagnosed with schwannomatosis in which no clinical symptoms of type 2 neurofibromatosis. The chief complain was pain. In adolescence and adult group, all masses were found. The locations were brachial plexus, popliteal fossa and hand. No hearing impairment, vertigo, tinnitus and visual disturbance was observed in any of the case. Family history was negative. In all cases, there was no evidence of vestibular schwannoma on cranial MRI imaging study. In all cases, Tinel sign was positive. Pathologic diagnosis was positive for schwannoma. Further study and case collection is needed to idenity the clinical manifestation, clinical course and genetic characteristic of schwannomatosis.

A 30-year-old woman who was diagnosed as peripheral neuroblastoma by fine needle aspiration of a soft mass of the right upper arm is described. She presented a slowly growing, soft mass of the right upper arm for 1 month. The right humerus revealed no abnormal finding on X-ray. Ultrasonogram of the right upper arm revealed a well demarcated, smooth marginated solid mass without invasion of adjacent structures. Fine needle aspiration was done under the impression of soft tissue tumor with undetermined biologic behavior. The aspirates were highly cellular and the tumor cells were dispersed both singly and in clusters of varying size. The clusters occasionally showed a central capillary core and rosette-like structures. The tumor cells were small in size and had a small to medium amount of cytoplasm. Some of them revealed slender cytoplasmic processes. The nuclei showed distinct nuclear membranes, finely clumped chromatin and small conspicuous nucleoli. Cellular pleomorphism or mitotic figure was not definite. These cytologic findings were interpreted as a malignant, non-lymphomatous small round cell tumor, most likely representing peripheral neuroblastoma or Ewing's sarcoma. Final diagnosis was confirmed by simple excision as peripheral neuroblastoma.
