Cardiac myxomas--surgical experience with a multi-faceted tumor.

Eleven patients underwent surgery for cardiac myxomas during an 11-year period. There were 7 females and 4 males, ranging in age from 21-75 (mean 55) years. Presenting symptoms were quite variable: paroxysmal shortness of breath (5), stroke (4), peripheral emboli (2), pulmonary emboli (2), palpitations (2) and fever of unknown origin (1). Diagnosis was made by angiography in 3 cases, echocardiography in 7 and intraoperatively in 1. Seven of the tumors were in the left atrium, two in the right atrium and 2 in the left ventricle. In two patients the tumor recurred. One patient died of a recurrent diffusely invading myxoma of the left ventricle. Ten patients are alive 1-10 years postoperatively (mean 6 years).

Liver findings in infantile cytomegalovirus infection: similarity to extrahepatic biliary obstruction.

The histological findings in the liver in four fatal cases of infantile cytomegalovirus (CMV) infection are presented, three occurred in premature infants, and all died at the ages of 2-4 months. Most previously reported cases showed various degrees of hepatitis with giant cell transformation. In three of our four cases, however, the main feature was cholestasis, portal fibrosis and bile duct proliferation, not unlike the findings seen in extrahepatic biliary obstruction. In one case, massive hepatic necrosis was found, a finding not previously reported in this disease. The diversity of liver findings in infantile CMV infection is stressed.

Cytomegaly in benign ovarian cysts.

We report two cases of benign ovarian cysts that revealed cytomegaly of the epithelial lining cells. One case was a large solitary luteinized follicle cyst of pregnancy and puerperium. The other case was an endometrial cyst. Changes in the cells included marked pleomorphism and hyperchromasia of the nuclei, large amounts of cytoplasm, and lack of mitotic figures. We ascribed these cellular features to hormonal effects and stress the importance of recognizing such changes and differentiating them from malignancy.

Conus ganglioglioma in a 2 1/2-year-old boy. Case report.

Gangliogliomas are rare tumors, primarily seen in patients under the age of 30 years. They occur least commonly in the spinal cord. This report presents a 2 1/2-year-old boy who harbored an intramedullary conus tumor with the light microscopic appearance of a ganglioglioma. The neurobiological behavior of this tumor is yet to be determined.

Laminins in lung development.

Laminins are essential components of basement membranes, playing important roles in cell adhesion, proliferation, and differentiation. These heterotrimeric glycoproteins are composed of an alpha, beta, and gamma chains held together by disulfide bonds. The first laminin identified, from the mouse Engelbreth-Holm-Swarm (EHS) tumor, is now referred to as laminin-1. Laminin-1 is expressed in the mouse developing lung by epithelial and mesenchymal cells and plays a role in branching morphogenesis. Since laminins are multidomain proteins, different laminin sites are engaged in promoting lung organogenesis by serving different functions at different stages of development. This study shows that the cross region of the molecule selectively promotes epithelial cell proliferation. The outer globular region of alpha 1 and beta 1 chains mediates laminin polymerization and thereby basement membrane formation and epithelial cell polarization. The inner globular region of laminin beta 1 chain binds to heparan sulfate proteoglycan and both stimulate lumen formation. While the combined effect of these laminin active sites results in normal lung tissue structure and branching morphogenesis, different developmental abnormalities of the lung may result from alterations in each of them.
