RESUMO
An increasing number of cases of cerebral embolism caused by cardiac myxoma have been reported. However, cerebral infarction caused by different types of emboli obstructing different vascular regions within a short period of time has not been reported. This is the first report to histologically confirm cerebral infarctions independently caused by thrombus and myxomatous embolus in a patient with cardiac myxoma within a period of 23 days. The first cerebral infarction was due to embolization of thrombus to the right middle cerebral artery, whereas the second was due to embolization of tissue from a mucinous tumor to the left middle cerebral artery. Both cerebral infarctions underwent mechanical thrombectomy, but unfortunately, we ultimately failed to save the patient's life. Therefore, further attention should be paid to the surgical resection and treatment of cardiac myxoma.
RESUMO
BACKGROUND: Leukocyte immunoglobulin-like receptor B2 (LILRB2) has recently been considered a promising tumor promoter in human cancers. MATERIALS AND METHODS: In this study, the expression of LILRB2 was assessed in 82 samples of surgically resected human hepatocellular carcinoma (HCC) tissues using immunohistochemistry (IHC). RESULTS: LILRB2 was overexpressed in HCC tissues and its expression was positively and significantly correlated with poor prognostic features of HCC patients, including poor cell differentiation, larger primary tumor size, and shorter overall survival. In addition, there was a positive correlation between the expression of LILRB2 and its classical ligand human leukocyte antigen G in human HCC tissues. CONCLUSION: LILRB2 might play an important role in HCC progression and correlate with poor prognosis of HCC.
