A 3-year-old male Tosa was presented the severe dyspnea, emaciation and dehy dration. By echocardiograpy, right ventricle was found to be a mobile mass dynamically occluding the right ostium atrioventriculare in the systolic phase. At necropsy, 14 days after ultrasonography multiple tumor masses of various size were observed in the heart base, right ventricular lumen, myocardium, lung and liver. Histopathologically, the tumor cells, arranged in sheets or nests, were diagnosed as metastatic intracavitary cardiac aortic body tumor

We report a case of tenosynovial giant cell tumor with severe bone erosion in the right fifth finger of a 46-year-old man. Throughout this case review, we describe the imaging findings of tenosynovial giant cell tumor with severe bone erosion and review the literatures regarding osseous lesions caused by tenosynovial giant cell tumor and their significance related to the differential diagnosis and patient treatment.

Collision tumor is a synchronous neoplasm wherein two histologically distinct tumors co-exist within the same anastomosis site. Collision tumor can occur in any organ, but the incidence is markedly rare. Additionally, preoperative diagnosis can be challenging to the radiologist. Herein, we report an age 60 male with collision tumor of rectal adenocarcinoma and diffuse large B-cell lymphoma, presented as a semi-annular wall thickening and bulky exophytic mass on MR imaging.

신경내분비 종양은 매우 드문 흉선 종양으로, Kultschizky 세포에서 유래하는 것으로 흉선종과는 다른 것으로 생각된다. 흥선 신경내분비 종양의 병리학적 진단은 광학 현미경 검사, 면역조직화학 염색 및 전자현미경의 소견을 바탕으로 한다. 흥선 유암종의 약 50%에서 내분비 질환을 가지며, 재발과 흉곽외 전이가 특징적이다. 초발 종양이나 재발의 경우에 외과적 절제가 가장 효과적이라고 생각되나, 항암치료나 방사선 치료의 역할은 분명하지 않다. 최근 외과적 절제가 시행된 흉선 신경내분비 종양을 경험하였기에 여기에 보고한다.

Endolymphatic sac tumor is rare, locally aggressive hypervascular tumor of papillary structure, arising from the endolymphatic duct or sac in the posterior petrous bone. We present four cases with this tumor. Two patients were male and the other two were female. Age of each patient was 15, 52, 58, and 67 years. Three patients presented with progressive hearing loss and sustained vertigo for months to years and another one was referred for the tumor detected in routine medical check-up. Preoperative embolization was performed in 3 patients. Complete excision of the tumor was achieved in all patients using translabyrinthine or retrosigmoid approach. Herein, we describe the clinical and radiographic features, surgical treatment and pathologic findings with a review of the literature.

Objectives : To evaluate the anti-tumor and synergic effect of Soonkiwhajungtang with doxorubicin. Methods : The inhibitory concentration (IC), $IC_{50}$ and $IC_{90}$ of single use of doxorubicin and Soonkiwhajungtang with their concomitant treatment against MKN-45 (human stomach carcinoma) cell line were observed using MTT (microculture tetrazolium test) assay. In addition, their anti-tumor effects were also observed in xenograft nude mice models against the MKN-45 cell line. Results : Soonkiwhajungtang has only minimal direct anti-tumor effect against MKN-45 cell line but it reduced general depressed signs induced by implantation of the tumor cell lines and increased the total WBC and lymphocyte numbers. Conclusions : It is considered or expected that Soonkiwhajungtang extract reduces the critical toxicity of doxorubicin and has favorable synergic anti-tumor effect when administered concomitantly with doxorubicin.

Objectives : To evaluate the anti-tumor and synergic effect of Bojungikkeehapdaechilki-tang (BJDC) with doxorubicin. Methods : The inhibitory concentration (IC), $IC_{50}{\;}and{\;}IC_{90}$ of single use of doxorubicin and BIDC with their concomitant treatment against Colon-26 (murine rectum carcinoma) cell line were observed using MTT (microculture tetrazolium test) assay. In addition, their anti-tumor effects were also observed in xenograft nude mice models against Colon-26 cell line. Results : BJDC had only minimal direct anti-tumor effect against Colon-26 cell line but it reduced general depressed signs induced by implantation of the tumor cell lines and increased the total WBC and lymphocyte numbers. Conclusions : It is considered or expected that BJDC extract is reducing the critical toxicity of doxorubicin and has favorable synergic anti-tumor effect when administered conconitently with doxorubicin.

Wilms' tumor is the most common malignant renal tumor in childhood. The brain metastasis of a Wilms' tumor with anaplastic histopathology is rare. We present the case of an 8-year-old girl with Wilms' tumor, who presented with multiple brain metastases 5 years after her primary diagnosis. The brain masses were diagnosed after a generalized tonic-clonic seizure attack. The big solid mass in the cerebellum was resected, and whole-brain radiotherapy was performed, after which, she succumbed to her disease. In the case of clinical suspicion, cranial surveillance should be included in the routine clinical work-up for Wilms' tumor. Combined aggressive therapy (surgery+radiotherapy+chemotherapy) should be applied whenever possible, for both better survival and palliative aspects.

A solitary fibrous tumor in the pleura has been reported occasionally, but extremely rare in themediastinum. The histogenesis of this tumor has been still in controverse, but recent studies paid attention to it a mesenchymal origin by the immunohistochemical and ultrastructural bases. A few cases, reported in the literature, suggest that the mediastinal solitary fibrous tumor occurs more commonly in adult and shows slightly higher incidence in women. Its aggressive behavior such as recurrence rate and distant metastasis, is more prominant than reported in solitary fibrous tumor of the pleura. No single histologic feature allows an assumption definite prognosis. Surgical resection of this tumor is usually curative although the recurrence or distant metastasis are reported in about half of the patients. This report is a case of solitary fibrous tumor in the mediastinum in a 16-year-old female patient.She underwent surgical resection and her postoperative result was satisfactory.

Granular cell tumor or also called Abrikossoff's tumor, is a rare benign tumor that can occur anywhere in the body. Granular cell tumor may single or multiple (synchronous or metachronous). Approximately half of all granular cell tumors occur in the head and neck. most commonly in the tongue. But granular cell tumors of the larynx are rare, accounting for only 7 to 10% of all reported cases. Laryngeal tumors are usually small and men are more frequently affected than women. The exact histogenesis is still not known but most recent data support the neurogenic Schwann cell origin. The preferred treatment is local excision using cold knife or laser. Radiation therapy is of little benefit. We report a case of granular cell tumor of the larynx which was confirmed by histopathology.
