Cytomorphometric and Morphological Analysis in Women with Trichomonas vaginalis Infection: Micronucleus Frequency in Exfoliated Cervical Epithelial Cells.

Objectives: The aim of this study was to explore the cytomorphometric and morphological effects of Trichomonas vaginalis in exfoliated epithelial cells.

Study Design: Ninety-six Pap-stained cervical smears were divided into a study group and two control groups as follows: T. vaginalis cases, a first control group with inflammation, and a second control group without inflammation.

Lymphatic differentiation in classic Kaposi's sarcoma: patterns of D2-40 immunoexpression in the course of tumor progression.

The recent development of lymphatic endothelium-specific immuno-indicators has given rise to research on the histogenesis of Kaposi sarcoma (KS), specifically focusing on its lymphatic root and differentiation. D2-40 is a new lymphatic marker that recognizes podoplanin and is easily applied to formalin-fixed paraffin-embedded human tissues. This study examined D2-40 immunoexpression in 178 classical KS lesions using immunohistochemical methods.

Elastofibroma: a clinicopathologic and immunohistochemical study of seven cases and literature review.

Elastofibroma is a rare fibrous lesion characterized by accumulated abnormal elastic fibers whose etiology remains largely unknown. In this study, we analyzed seven cases of elastofibroma to further explore the characteristics of its cellular composition. Immunohistochemistry was performed for mast cell tryptase, S-100 protein, vimentin, CD34, smooth muscle actin, desmin and collagen type IV.

Primary stromal tumor of the omentum: Report of a case.

We report the case of a primary extragastrointestinal stromal tumor (EGIST) found in the omentum of a 65-year-old woman. The resected specimen, which measured 6 cm at its largest point, consisted of an outer solid part and inner uniloculated cysts. Microscopically, the tumor was characterized by interlacing bundles of elongated spindle cells, with the nuclei showing a focal palisading pattern; however, skenoid fibers were not observed anywhere and mitoses were absent.
