Salivary gland carcinomas displaying exclusively myoepithelial differentiation (myoepithelial carcinoma) are considered rare. Their histopathologic features, immunohistochemical profile, and clinical behavior are not well characterized. The authors reviewed the clinicopathologic features of 25 salivary gland tumors fulfilling two fundamental histologic(More)
OBJECTIVE To validate a previously reported discriminant rule for predicting mortality in adult patients with primary community-acquired pneumonia and to determine which factors available at hospital admission predict a fatal outcome among such patients. DESIGN Historical cohort study. SETTING University hospital. PATIENTS Adults admitted to the(More)
OBJECTIVE To investigate the association of a variety of cell surface and cytoplasmic antigens in small cell carcinoma of the lung with long-term survival (greater than 2 years). DESIGN Using immunohistochemical analysis of small cell carcinomas, the tissue expression of corticotropin, bcl-2, p-glycoprotein, cathepsin B, cathepsin D, CD44,(More)
Variations in either the polypeptide sequence or the carbohydrate moieties of transferrin may result in altered electrophoretic mobility of this molecule. We report a case of an allelic (polypeptide) variant of transferrin with mobility similar to that of the beta 2 (sialic acid-depleted) transferrin found in cerebrospinal fluid (CSF) and a few other body(More)
Indeterminate cell tumor is an extremely rare neoplasm that mainly occurs in the skin. We report a case of indeterminate cell tumor arising from the spleen, a previously unreported site for indeterminate cell tumor. Histologically, the tumor showed nests, nodules, and sheets of large polygonal cells with mostly oval nuclei; open chromatin; variable(More)
In 28 serum and plasma samples from patients with systemic lupus erythematosus, we examined the importance of antibody class with respect to complement-mediated binding to human red blood cells (RBC) of antibody/DNA immune complexes (IC) prepared with anti-DNA antibodies. We used both 3H-double-stranded DNA and 3H-single-stranded DNA (ssDNA). Generally,(More)
