Tumors of the heart and the great vessels are very rare disease, and there are many disorders such as tumors originated from the heart and great vessels, metastatic tumors, and tumor-like lesions which do not fit into the usual concept of tumor or neoplasm; thus, it is very difficult to classify these tumors. We proposed a new classification of cardiovascular tumors for clinical use based on th...

Common causes of right sided intra-cardiac atrial masses include primary cardiac tumors (atrial myxoma), atrial thrombus, tumor thrombus with hepatocellular or other thoracoabdominal cancers and metastatic lesions. Invasion of atria by gastrointestinal tumors is rare and that with esophageal ones seldom observed. Esophageal cancers rather present with dysphagia, odynophagia or systemic symptoms...

A 7-year-old male with bilateral palpable testicular masses was found to have metastatic stage IV Wilms' tumors associated with both left renal and lung lesions. The patient was treated successfully with testicular-sparing bilateral partial orchiectomies, radical nephrectomy, chemotherapy, and radiation, with 8 years free of recurrence. This is the only reported case of bilateral testicular tum...

PURPOSE Metabolism and water diffusion may have a relationship or an effect on each other in the same tumor. Knowledge of their relationship could expand the understanding of tumor biology and serve the field of oncologic imaging. This study aimed to evaluate the relationship between metabolism and water diffusivity in hepatic tumors using a simultaneous positron emission tomography/magnetic re...

Tumor is defined as a kind of chronic diseases by the World Health Organization. The integrative traditional Chinese and western medicine works well on treatment tumors, even in advanced patients or with recurring metastatic tumor. However, pathogenic mechanism tumors still unclear. Therefore, based 19th pathogenesis Yellow Emperor's Internal Class that "Diseases producing liquid clear chill al...

background and objective: clinical behavior of basal cell carcinoma (bcc) is known to be different according to histological growth pattern and basosquamous cell carcinomas (bsc) are known with their aggressive behavior and metastatic capacity. in this study, we evaluated bcl-2 and cyclin d1 expressions in bcc and bsc cases comparatively, to explore their predictive value on the aggressive beha...

Metastatic spinal tumors are usually quite difficult to treat. In patients with metastatic spinal tumors, conventional radiotherapy fails to relieve pain in 20-30% of cases and open surgery often causes considerable trauma and complications, which delays treatment of the primary disease. Percutaneous vertebroplasty (PVP) is considered to be useful in achieving rapid pain control and preventing ...

Obesity is correlated with increased incidence of breast cancer metastasis; however, the mechanisms underlying how obesity promotes metastasis are unclear. In a diet-induced obese mouse model, enhanced lung in both presence and absence primary mammary tumors recruitment myeloid lineage cells into lungs. tumors, mice demonstrated numbers elevated collagen fibers within stroma, reminiscent premet...

Clear cells can be found in numerous salivary and non-salivary tumors in the head and neck region, including metastatic lesions. They are rare low-grade tumors accounting for less than 1% of all salivary gland tumors and occur almost exclusively in the intra-oral minor salivary glands. Hyalinizing clear cell carcinoma (HCCC) is an extremely rare and recently described neoplasm predominantly aff...

We studied, by immunohistochemical analysis, the expression of MUC1 and epithelial membrane antigen in 44 stage pT1 renal cell carcinomas (RCCs). Six patients had a metastatic evolution. The percentage of stained cells was determined for each tumor. All tumors and normal adjacent renal parenchyma were stained. In normal kidney, distal convoluted tubules and collecting ducts stained strongly wit...
