Cytology of cardiac myxomas: presence of Ulex europaeus agglutinin-I (UEA-I) lectin by immunoperoxidase staining.

Numai utilizatorii înregistrați pot traduce articole

Cytological findings are presented of seven cases of cardiac myxomas. Avidin-biotin-peroxidase complex (ABC) method was employed to demonstrate Ulex europaeus agglutinin-I (UEA-I) lectin in imprint smears as well as in paraffin-embedded tissue sections in cardiac myxomas. The cytology was

The clinicopathologic features of 107 cardiac myxomas are presented. Eighty-one were in the left atrium, 18 in the right atrium, and 8 were biatrial or located in the ventricles. The mean age at presentation was 50 years and did not vary significantly by sex, race, or site in the left or right

Cardiac myxoma: morphologic, histochemical, and tissue culture studies.

Numai utilizatorii înregistrați pot traduce articole

Twenty-one cases of cardiac myxoma exhibiting a variety of histologic findings were investigated by light and electron microscopy, tissue culture, and immunohistochemical studies for factor VIII-related antigen (FVIII-RA) and Ulex europaeus 1 (UEA-1) lectin. The cardiac myxoma cells revealed

Cardiac myxomas. An immunohistochemical study using endothelial, histiocytic, and smooth-muscle cell markers.

Previous immunohistochemical studies of cardiac myxomas are few in number, limited in scope and, in part, discrepant. We studied the immunoreactivity of five cardiac myxomas for factor VIII-related antigen, Ulex europaeus agglutinin I, smooth-muscle myosin, alpha 1-antitrypsin, and alpha

Immunohistochemical expression of endothelial markers in left atrial myxomas: a study of six cases.

Vascular endothelial cells are antigenically heterogeneous and therefore it has been recommended that a range of immunohistochemical markers is employed to show the presence of cells of endothelial origin in surgical pathology. In this study we applied three monoclonal antibodies--to factor

Phenotypic characterization of cellular components of cardiac myxoma: a light microscopy and immunohistochemistry study.

Numai utilizatorii înregistrați pot traduce articole

Cardiac myxoma is the most common primary tumor of the heart. A detailed evaluation of cell types in 41 cardiac myxomas by light microscopy and in 30 cases by immunohistochemistry was made. Reactivity to the various antisera were observed in the surface lining cells, the stromal myxoma cells and the

Angiosarcoma of the left atrium mimicking myxoma: case report.

Numai utilizatorii înregistrați pot traduce articole

The case of a 65-year-old female patient with a pedunculated left atrial angiosarcoma is presented. Histologically, the tumor was composed of vascular spaces lined by atypical cells with similar cells in the solid portion of the tumor. Immunohistochemical stain for factor VIII-related antigen was

Ovarian myxoma: clinicopathologic and immunocytologic analysis of five cases and a review of the literature.

Numai utilizatorii înregistrați pot traduce articole

The clinical and pathological features of five personally observed ovarian myxomas and three similar tumors previously described in the literature are analyzed. The patients' ages ranged from 16 to 45 years (mean, 33 years). An asymptomatic unilateral adnexal mass was the usual presentation. The

Angiosarcoma of the heart: structural and ultrastructural study.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Primary cardiac tumours are rare. Nearly 70% of primary cardiac tumours are benign, the majority of which are represented by myxomas. The most frequent primary cardiac neoplasm is the angiosarcoma that represents 31% of primary cardiac malignant. We report a particular clinical case of

Surgical pathology of primary cardiac and pericardial tumors.

OBJECTIVE Retrospective study of surgical pathology experience on cardiac and pericardial tumors at the University of Padua in the era of immunohistochemistry and endomyocardial biopsy. METHODS In the period 1970-1995, we studied 125 bioptic primary neoplasms: specimens were obtained from surgical
