Abstract:
Rapidly growing papillary fibroelastoma complicated by myxoma is extremely rare. An 80-year-old male was transported to our hospital because of cerebral hemorrhage. Echocardiogram revealed a massive pedunculated tumor in the septum of the left atrium. The tumor extended to the mitral valve orifice and posed a risk of strangulation, yet removing it immediately would have required cardiopulmonary bypass with anticoagulant, which would have posed a serious risk of rebleeding. Magnetic resonance imaging showed that the tumor stalk was sufficiently thick for us to perform a standby surgery 1 month after cerebral hemorrhage. Follow-up echocardiogram prior to this surgery revealed a new, high-mobility tumor in the right ventricular septum. We resected these two tumors together. Histopathological examination showed that the tumor of the left atrium was a myxoma and the tumor of the right ventricle was a papillary fibroelastoma. The patient had a good postoperative course and was discharged without complications.

01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
