  • 특이 병력 없던 15세 남자가 내원 한 달 전부터 시작된 우측 흉통과 함께 기침을 호소하여 본원 응급실로 내원하였다. 흉부 전산화 단층촬영에서 $10\times15\times16cm$크기의 전 종격동 종양으로 상대 정맥과 심장을 압박하면서 침범하고 있는 소견을 보였다. 수술 절제가 불가능한 것으로 판단하여 항암 및 방사선 치료를 시행하였다. 이후 종양 표지자는 거의 정상화되었으나 오히려 종양의 크기가 증가하는 소견을 보여, 종격동의 성장 기형종 증후군(Mediastinal Growing Teratoma Syndrome)으로 판단되어 수술을 시도하였다. 종양의 수술적 제거 후 환자는 24개월째 잔존 종양 및 재발 없이 외래 관찰 중이다.

  • Meningioma is relatively common, benign, and extra-axial tumor accounting for about 20% of primary brain and spinal cord tumors. The World Health Organization (WHO) classified these tumors into Grade I (benign), Grade II (atypical), and Grade III (anaplastic) meningioma. Grade I meningioma which is slowly growing tumor and have some rare subtypes. Among them, metaplastic subtype is defined as a tumor containing focal or widespread mesenchymal components including osseous, cartilaginous, lipomatous, myxoid or xanthomatous tissue, singly or in combinations. We report a rare metaplastic meningioma overspreading nearly whole cerebral convexity from main extra-axial tumor bulk in the parietal lobe.

  • Purpose: Malignant peripheral nerve sheath tumor without neurofibromatosis type 1 is very rare neoplasm. Development in the superficial soft tissue is exremely rare. Authors experienced one rare case of primary malignant peripheral nerve sheath tumor developed on abdomen. The clinical and histologic findings were described. Methods: An 83-year-old man visited hospital with an $11{\times}6.5{\times}4.5$ cm sized ulcerated and hemorrhagic mass on abdomen. The tumor was localized in abdominal skin and started growing 3 years ago. Results: Wide excision with safety margin of 2 cm and limberg flap was done. The postoperative biopsy revealed a malignant peripheral nerve sheath tumor. There was no evidence of recurrence of tumor for 16 months. Conclusion: Malignant peripheral nerve sheath tumor is an aggressive malignant tumor. An abrupt enlargement of size, ulceration and bleeding are suggestive of malignant chnages of the tumor. We recommand early wide excision with enough safety margin as treatment of malignant peripheral nerve sheath tumor.

  • The present study was undertaken to investigate the effect of in vivo administration of neem oil intra-peritoneally (i.p.) to mice bearing a progressively growing transplantable T cell lymphoma of spontaneous origin, designated as Daltons lymphoma (DL), on the tumor growth. Mice were administered various doses of neem oil mixed in groundnut oil, which was used as a diluting vehicle or for administration to control DL-bearing mice. Administration of neem oil resulted in an acceleration of tumor growth along with a reduction in the survival time of the tumor-bearing host. Neem oil administered DL-bearing mice showed an augmented apoptosis in splenocytes, bone marrow cells and thymocytes along with an inhibition in the anti-tumor functions of tumor-associated macrophages. Thus this study gives an altogether a novel information that neem oil instead of the popular belief of being anti-tumor and immunoaugmentary may in some tumor-bearing conditions, behave in an opposite way leading to an accelarated tumor progression along with a collapse of the host's anti-tumor machinery. These observations will thus have long lasting clinical significance, suggesting caution in use of neem oil for treatment of cancer.

  • Warthin's tumor is a benign neoplasm that most frequently occurs in the parotid gland. Warthin's tumor shows a tendency of bilateral occurrence, but most of bilateral tumors occur at different time. It usually affects older man and grows slowly. Surgical excision is appropriate treatment for patients with Warthin's tumor and rarely recurs after removal. We report a rare case of bilateral Warthin's tumor which detected at the same time. A 54-year-old man had painless, slowly growing masses on the both mandibular angles. The masses were detected ten years ago. CT scan, ultrasonographic evaluation and fine needle biopsy was performed for preoperative diagnostic study. Superficial parotidectomy was done one after the other at ten-day intervals. After excision, histological examination revealed a mixture of ductal epithelium and a lymphoid stroma. The overlying surface of lymphoid tissue was covered with epithelial cells that was abundant of eosinophilic cytoplasm. Both masses were diagnosed as Warthin's tumor. Postoperatively, the patient did well and had no evidence of recurrence of tumor for 2 years follow-up period. Authors experienced a rare case of bilateral Warthin's tumor which detected at the same time. We recommend stepwise superficial parotidectomy at one or two-week intervals as treatment of bilateral Warthin's tumor.

  • We analyzed retrospectively the 74 patients with salivary tumors who were treated surgically at Chonbuk National University Hospital. The following results were obtained: 1) The most prevalent site was parotid gland and minor salivary gland is second in order. The most prevalent site of minor salivary gland tumor was palate. 2) Slow-growing painless mass was the most common chief complaints. 3) The most frequnet age incidence was 4th and 6th decades. 4) Sex ratio of male to female was 1:1.1, but in minor salivary gland tumor, female was more prevalent and sex ratio of male to female was 1:1.5. 5) Histopathologically, the most common salivary gland tumor was pleomorphic adenoma. Among the benign tumors, the pleomorphic adenoma was most common and Warthin's tumor was next. Among the malignant tumors, the mucoepidermoid carcinoma was most common and adenoid cystic carcinoma, adenocarcinoma were the next. 6) 59 patients with benign tumor and 15 patients with malignant tumor were treated with operative therapy. Among patients with malignant tumor, 12 patients were treated with postoperative radiation therapy. 7) Overall incidence of postoperative complication was 14.9% and the most common complication was transient facial nerve weakness and hematoma.

  • Recently, we experienced a case of rare neurilemmoma originated from intercostal nerve [9th] in the right chest wall in a 25 year old male officer. The tumor was incidentally found in the routine chest X ray, where the round well circumscribed mass tumor the ninth rib with notching and sclerotic margin, suggesting slowly growing benign benign of chest wall was revealed and the tumor mass was easily extirpated in the exploratory thoracotomy, with uneventful recovery. Grossly, the tumor was firm, partly soft and well circumscribed, measuring 4.5X3.0X 3.0 cm with yellowish smooth outer surface, attached with intercostal nerve trunk. Cut surface exhibits partly grayish white and largely hemorrhagic areas. Microscopically, the characteristic palisading arrangement of schwann cells and Verocay bodies are seen but dominant features are cystic degeneration and hemorrhage with organization and fibrosis. The sheath of intercostal nerve and capsule of neurilemmoma were con joined. There is no evidence of malignancy. The tumor was confirmed as neurilemmoma of intercostal nerve, Antony type B.

  • The calcifying epithelial odontogenic tumor is a rare benign odontogenic neoplasm which was first described by Pindborg in 1955 and accounts for less than 1% of all odontogenic tumors. The tumor occurs primarily in the molar-premolar region of the mandible, and 52% of cases are associated with an unerupted tooth. The clinical feature is most commonly a slow-growing painless swelling. The tumor may show considerable radiographic variation and usually characteristic histopathologic features. In this study, we report a case of the calcifying epithelial odontogenic tumor on the left mandibular body and ramus area in a 28-year-old male with a brief review of the concerned literatures.

  • 간 전이 암은 이전에는 수술을 통한 외과적 절제가 주요 치료기법이었지만 방사선 치료 기법의 발전으로 인해 점차 방사선치료의 시행이 늘어나고 있다. 18F-FDG PET 영상은 간 전이 암 진단 시 더욱 우세한 민감도와 특이도를 보이며, 치료계획용 CT 영상과 더불어 종양조직의 위치를 정의하는 중요한 영상장비로 자리매김하고 있다. 본 연구에서는 간 전이 암의 18F-FDG PET 영상에 나타난 종양영역을 영상분할기법 적용하였으며 PET영상의 여러 인자들이 영상분할기법들에 미치는 영향을 알아보았다. 2009년부터 2012년까지 방사선 치료를 받은 간전이 환자들 중 18F-FDG PET/CT 촬영을 시행한 13명의 환자들의 치료계획용 CT와 PET/CT 영상을 얻었다. 그 뒤 PET 영상의 관심영역을 설정하기 위하여 3가지 영상 분할 기법인 상대적문턱기법, 기울기기법, 영역성장기법을 적용하였다. 이 결과들을 바탕으로 GTV와 각 영상 기법으로 구현된 종양 영역과 부피 비교를 시행하였으며 영상 분할 기법에 영향을 미치는 영상인자들과의 관계를 회귀 분석하였다. GTV (Gross Tumor Volume)의 평균 부피는 $60.9{\pm}65.9$ cc이며, 40% 상대적문턱값 기법은 $22.43{\pm}35.3$ cc, 50% 상대적문턱값 기법은 $10.11{\pm}17.9$ cc, 영역성장기법은 $32.89{\pm}36.8$ cc, 기울기기법은 $30.34{\pm}35.8$ cc로 나타났다. 기존의 GTV와 가장 유사한 영역을 나타낸 영상 분할 기법은 영역성장기법 이었다. 이 영역성장기법에 영향을 미치는 영상인자를 정량적으로 분석하기 위해 표준화 계수 ${\beta}$값을 이용하였으며, GTV의 크기, $TumorSUV_{MAX/MIN}$, $SUV_{max}$, TBR 순으로 나타났다. 이와 같은 PET 영상인자를 반영한 영상 분할 기법을 이용해서 종양 영역을 정의한다면 보다 정확하고 일관성 있는 종양그리기를 수행할 수 있으며 궁극적으로 종양에 최적화된 방사선량을 투여할 수 있을 것이다.
