Non-secretory multiple myeloma (NSMM) is a rare cancer of plasma cells characterized by the absence of detectable monoclonal M protein in the blood or urine. A 57-year-old woman presented with mandibular pain but without intraoral swelling. Imaging studies revealed multiple osteolytic lesions in her mandible and pronounced root resorption of the left mandibular second molar. Biopsy results showed atypical plasmacytoid cells positive for anti-kappa, CD138, MUM1, and CD79a antibodies, but negative for anti-lambda and CD20. These results were indicative of a malignant plasma cell neoplasm. No abnormalities were revealed by free light chain assay or by serum or urine protein electrophoresis, leading to a diagnosis of NSMM. The patient began chemotherapy in conjunction with bisphosphonate therapy and achieved remission following treatment. This case underscores the critical role of dentists in the early detection and prevention of NSMM complications, as the disease can initially present in the oral cavity.

Castleman's disease is a relatively rate disorder of lymphoid tissue and poorly understood etiology. The disease may occur anywhere along the lymphatic chain, but is most commonly found as a solitary mass in the mediastinum. The hyaline vascular type represents 91% of Castlemen's disease, and these are most often discovered in the asymptomatic patient on routine chest film. Patients with the plasma cell type often exhibit systemic symptoms, including fever, night sweats, anemia, and hypergammaglobulinemia. Surgical excision effects cure, although resection of the hyaline vascular type may be associated with significant hemprrage owing to extreme vascularity. We recently experienced a case of hyaline vascular type Castleman's disease which was treated by surgical resection through the anterior mini-thoracotomy, and report with its review.

This study investigated the effect of red ginseng extract on metastasis of colon cancer cells in vitro and in vivo. Wound healing migration, cell motility, invasion, and activity, protein expression, and mRNA expression of matrix metalloproteinases (MMPs) were examined in SW480 human colon cancer cells. SW480 cells were cultured with or without $100{\mu}g/L$ PMA in the absence or presence of various concentrations (100, 200, or $300{\mu}g/mL$) of red ginseng extract. Red ginseng extract treatment caused signifi cant suppression of cell motility and invasion (p<0.05) in SW480 cells. Red ginseng extract inhibited MMP-2 and MMP-9 activity and their protein and mRNA expression in a dose-dependent manner (p<0.05) in SW480 cells. For experimental metastasis, BALB/c mice were injected intravenously with CT-26 mouse colon cancer cells in the tail vein, and were orally administered various concentrations (0, 75, 150, or 300 mg/kg body weight) of red ginseng extract for 3 weeks. Numbers of pulmonary nodules were signifi cantly decreased in mice that were fed red ginseng extract (p<0.05). Plasma MMP-2 and MMP-9 activity signifi cantly decreased in response to treatment with red ginseng extract in mice (p<0.05). These data suggest that red ginseng extract may be useful for prevention of cancer invasion and metastasis through inhibition of MMP-2 and MMP-9 pathways.

목적: 말기암환자의 여명 예측은 치료의 이득과 위해를 판단하는 잣대가 되고, 적절한 의료 중재 제공 및 환자의 자율성에 기초한 의사결정에 중요한 기준이 된다. 특히 많은 수의 말기암환자는 다발성 장기 부전으로 사망에 이르기 때문에 본 연구에서는 이를 반영할 수 있는 혈장 내독소 농도와 생존기간과의 연관성을 알아보고자 하였다. 방법: 2009년 4월부터 10월까지 6개월 동안, 만 20세 이상의 말기암환자 56명을 대상으로 혈장 내독소 농도를 측정하고, 생존기간을 조사하였다. 나이, 성별, 원발 암 부위, 암 치료 경력, 전이여부, 투약상황 및 활력 증후, Karnofsky 수행지수 등의 신체검사, 백혈구 수, 혈색소, 적혈구용적률, aspartate aminotransferase, alanine aminotransferase C-반응성 단백질, 총 빌리루빈, 내독소 등의 혈액검사를 시행하였다. 결과: 혈장 내독소 농도, 성별, 나이, 백혈구 수, 혈색소, 적혈구 용적률, AST, ALT, 총 빌리루빈, C-반응성 단백질, 통증강도를 단변량 분석한 결과 혈장 내독소 농도는 생존기간과 통계적으로 유의한 관계를 보이지는 않았으나, 단변량 분석에서 생존기간에 유의한 영향을 미치는 성별, 백혈구 수, 총 빌리루빈을 포함하여 시행한 다변량 분석에서 혈장 내독소 농도는 생존기간과 통계적으로 유의한 관계가 있는 것으로 나타났다. 결론: 다발성 장기 부전과 관련이 있는 혈장 내독소 농도는 생존기간 예측인자로서 쓰일 수 있는 가능성을 보여 주었다.

염증성 근섬유모세포종(inflammatory myofibroblastic tumor)은 드문 종양으로, 조직학적으로 근섬유모세포성 방추세포의 증식과 다양한 염증 세포들의 침윤을 특징으로 한다. 이 종양은 전신의 모든 해부학적 위치에서 생길 수 있으나 주로 폐, 장간막, 대망에서 생긴다고 보고되어 있으며, 대부분의 경우 어린이 또는 젊은 성인에서 발생한다. 췌장에서 발생하는 경우는 매우 드물며, 악성 종양을 포함한 다른 종양과 구별하기 어렵기 때문에 정확한 영상의학적 진단이 어려운 경우가 흔하다. 이에 저자는 중년 여성의 췌장 두부에서 발생한 염증성 근섬유모세포종의 사례를 초음파, 컴퓨터단층촬영, 자기공명영상 소견들과 함께 제시하고 문헌을 검토하고자 한다.

This report deals with a 9-year-old neutered male Yorkshire terrier that had been suffered from vomiting, bloody diarrhea, anorexia. On exploratory laparotomy, pale-pink $10{\times}6cm$ duodenal mass was found and submitted to the Department of Veterinary Pathology, College of Veterinary Medicine, Seoul National University. Histologically, the duodenal mass consisted of compact sheet of poorly demarcated, highly infiltrative neoplasm. The neoplastic cells were round to polygonal and contained scant to moderate amounts of granular basophilic cytoplasm and eccentrically located irregularly round nuclei with stippled chromatins. The neoplastic cells were positive to lamda light chain immunohistochemically but were uniformly negative for toluidine blue stain and giemsa stains. Based on these results, this case was diagnosed as primary extramedullary plasma cell tumor of duodenum.

Solitary plasmacytoma is a rare malignant neoplasm that originate in immunoglobulin-producing plasma cell. Solitary bone plasmacytoma can be found at any site throughout the skeleton and in most cases eventually progresses to multiple myeloma, of which it is thought to be an unusual presentation. On the other hand, extramedullary plasmacytoma has a tendency to occur in the head and neck region, mainly in association with the upper air passages. Incisional biopsy is the primary approach to make a definitive diagnosis, and immunohistochemical staining can be very helpful in understanding the nature of these tumors. We report a 66 years old patient with solitary bone plasmacytoma and a 36 years old patient with solitary extramedullary plasmacytoma with literatures review.

Surgery and radiotherapy are mainly used for plasma cell neoplasm which constitutes about $1{\sim}2%$ of human malignancy. The authors carried out Fractionated Stereotactic Radiotherapy[FSRT] on the residual tumor after the subtotal removal of Intracranial plasmacytoma. A huge mass lesion was observed on MRI [magnetic resonance image] in the left anterior and middle cranial fossa of a 63-year-old man with left exophthalmus which lasted for a month, and was suspected as a meningioma with strong contrast enhancement. Extramedullary plasmacytoma was diagnosed on histopathological examination. After the surgery, FSRT was also carried out on the residual tumor which invaded the skull base. One-year follow up after FSRT showed contrast enhancement only in the left sphenoid bone on MRI, which indicated significant decrease in the size of the tumor without any abnormal neurologic deficits. We treated intracranial plasmacytoma which invaded left anterior and middle cranial fossa and surrounded cavernous sinus without cranial nerve deficit through subtotal tumor removal and FSRT.

Castleman's disease is an uncommon lymphoproliferative disorder. The disorder can be classified based on histological subtype, such as hyaline vascular type, plasma cell type, and mixed type, and can also be clinically divided into either unicentric or multicentric type. Its exact pathophysiology is not clearly identified. The unicentric type is able to be treated by surgical resection. However, there is no standard treatment modlity for the multicentric type. Treatment of multicentric type includes anti-cancer chemotherapy and radiation therapy. Recently, authors have experienced a rare case of unicentric type of Castleman's disease accompanying a mucoepidermoid carcinoma of parotid gland and report a case which is discussed with references.

고립성 골형질세포종은 형질세포종양의 $3{\sim}5%$를 차지하는 드문 질환이며 특히, 늑골에 발생한 고립성 골형질세포종에 관해 국내에서는 아직 보고된 바가 없다. 54세 남자 한자가 검진 시 시행한 단순가슴 사진에서 폐종양으로 의심되는 병변이 있어 타병원에서 전원되었다. 전산화 단층 촬영 및 양전자 방출 단층 촬영 결과 좌측 6번째 늑골의 종양으로 진단되어 수술적 절제를 하였다. 병리 검사 결과 골형질세포종으로 진단되었으며 술 후 선별검사에서 다발성 골수종의 증거는 없었다. 술 후 방사선 치료는 하지 않았으며 2년째 추적 관찰 중이나 새로운 병변은 발견되지 않았다.
