Chondrosarcoma is a very uncommon malignant primary bone tumor, especially, it occurs extremely rare in the spine. A 52-year-old man was admitted to the emergency room with sudden paraplegia. Twelve hours prior to a paraplegic event, he visited an outpatient clinic with discomfort and tenderness around the medial border of the right scapular, and his neurologic status was absolutely intact. Magnetic resonance imaging showed a lobulated soft tissue mass from T3 to T5, which extended to the epidural space. Computed tomography scans showed soft tissue mass on the spinal posterior arch and osteolytic change of the adjacent bony structures. Emergent surgery was performed and the lesion was removed. Dark reddish blood and gel-like material were encountered around the dura and posterior arch during the operation. Multiple pulmonary nodules were found on a chest CT scan and a biopsy of one of them had been proven to be a metastasis of chondrosarcoma. The histologic examination showed dedifferentiated chondrosarcoma. The patient's neurologic deficit was improved slowly from ASIA A to ASIA D. Chondrosarcoma in the spine is extremely rare, even more with acute hemorrhage and sudden expansion into the epidural space. We named it chondrosarcoma apoplexy. We should consider the possibility of a hemorrhagic event when the patient's neurologic deficit worsens suddenly with spinal bone tumor.

Ameloblastomas are rare odontogenic epithelial tumors that occur mainly in the mandible. Despite their benign histologic appearance, they are locally aggressive with a high recurrence rate. However, a metastasizing ameloblastoma has been rarely reported. According to the current World Health Organization classification system, the definitive diagnosis of metastasizing ameloblastoma can only be carried out in retrospect, after the event of metastasis. This case report describes a patient with metastatic pulmonary ameloblastoma, 17 years after the surgical excision of an odontogenic tumor, preoperatively misdiagnosed as primary squamous cell carcinoma.

Tc99-IDAs를 이용하여 원발성 간세포암뿐만 아니라 폐에 전이된 간세포암까지 확인할 수 있다는 보고가 있었기에 저자들은 원발성 간세포암에서 폐전이가 의심되는 환자에게 Tc99m-DISIDA를 이용하여 간 및 폐를 주사하여 흉부 X-선상의 폐전이와 일치하는 주사상의 열소를 확인하였으며 이는 우리나라에 많은 간세포암의 진단과 수술전 전이유무의 평가 및 치료설정에 도움이 될 수 있을 것으로 생각되어 보고하고자 한다.

The lung is one of the most frequent sites of metastasis for extrathoracic tumors. Certain malignancies show a particular tendency to metastasize to lung, and in 15 to 25% of these cases, lung involvement is the only manifestation of metastatic disease. The most common presentation is the form of multiple bilateral nodules or masses of varying sizes. Lymphangitic metastasis is comprising 6 to 8% of all pulmonary metastasis. A striking variant of parenchymal involvement occures when dyscohesive tumor cells fill alveoli to produce a tumoral pneumonia. Carcinomatous lymphangitis of prostate origin is infrequent and usually carries a poor prognosis, and tumoral pneumonia of it is extremely rare. We report herein a case of prostate carcinoma metastasizing to lung, simulates atypical pneumonia, and disclosed by acute chest illness.

Background: Increasing evidence from animal, epidemiological and clinical investigations suggest that dietary anthocyanins have potential to prevent chronic diseases, including cancers. It is also noteworthy that human epidermal growth factor receptor 2 (ErbB2) protein overexpression or ErbB2 gene amplification has been included as an indicator for metastasis and higher risk of recurrence for breast cancer. Materials and Methods: The present experiments investigated the anti-metastasis effects of black rice anthocyanins (BRACs) on ErbB2 positive breast cancer cells in vivo and in vitro. Results: Oral administration of BRACs (150 mg/kg/day) reduced transplanted tumor growth, inhibited pulmonary metastasis, and decreased lung tumor nodules in BALB/c nude mice bearing ErbB2 positive breast cancer cell MDA-MB-453 xenografts. The capacity for migration, adhesion, motility and invasion was also inhibited by BRACs in MDA-MB-453 cells in a concentration dependent manner, accompanied by decreased activity of a transfer promoting factor, urokinase-type plasminogen activator (u-PA). Conclusions: Together, our results indicated that BRACs possess anti-metastasis potential against ErbB2 positive human breast cancer cells in vivo and in vitro through inhibition of metastasis promoting molecules.

간세포암은 전 세계적으로 가장 흔한 악성 종양 중의 하나로, 간세포암의 간 외 전이는 주로 폐, 림프절, 뼈, 부신 등에 발생한다. 하지만 간세포암의 골격근 전이는 매우 드물고, 보고된 문헌도 흔치 않다. 42세 여성 환자가 우측 대퇴부에 압통이 동반된 연부조직 종괴를 주소로 내원하였다. 7년 전 간세포암과 폐전이가 진단되어 치료를 받은 기록이 있었으며 영상학적 검사 및 혈액 검사 결과 등에서 간세포암의 반막양근 내 전이가 의심되어 절개 생검술을 시행하였고 전이성 간세포암으로 밝혀져 광범위 절제술을 시행하여 치료하였다. 이를 문헌고찰과 함께 보고하고자 한다.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a useful, safe diagnostic modality for evaluating mediastinal and hilar lymphadenopathy. We report a 51-year-old male who presented with a left renal mass and multiple pleural masses without lung parenchymal lesions. The pleural masses were thought to be metastatic tumors or malignant mesothelioma. The patient underwent two percutaneous needle biopsies of the pleural mass, but the specimens were insufficient for a histopathological diagnosis. Because one pleural mass was adjacent to the right main bronchus, we decided to perform EBUS-TBNA for the pleural mass. As a result, sufficient core tissue was obtained with no complications, and the histopathological findings were consistent with metastatic papillary renal cell carcinoma. To our knowledge, this is the first case of using EBUS-TBNA for a pleural mass.

Urothelial carcinomas (UCs) can occur in the upper urinary tract or lower urinary tract. Upper urinary tract urothelial carcinoma (UUT-UC) is relatively a rare disease and accounts for only about 5% of UC cases. Sporadic cases of late-onset metastasis, associated with UC of the bladder, have occasionally been reported. In contrast, no late-onset distant metastatic UUT-UC without local recurrence has, to the best of our knowledge, been reported in the English literature. We report an extremely rare case of distant metastatic UC, mimicking lung adenocarcinoma that originated from UUT-UC 12 years previously.
