 Abstract
- Vimentin is an intermediate filament protein normally expressed in mesenchymal cells, but the evidence of the aberrant expression of vimentin in epithelial cancer cells suggests that the vimentin expression might be related to local invasiveness and metastatic potential. There have been a few previous studies on the vimentin expression in human cervical carcinogenesis using in vivo and in vitro models.
We examined the immunohistochemical vimentin expression in various squamous epithelial neoplasms of the uterine cervix, including the cervical intraepithelial neoplasia group (n=25), the microinvasive squamous cell carcinoma group (n=15), the invasive squamous cell carcinoma group (n=15) and the metastatic squamous cell carcinoma group (n=8).
Vimentin positivity was significantly higher in the invasive than in the intraepithelial group, and in the cases with lymph node metastasis than in those without metastasis, suggesting a relationship between the vimentin expression and progression of the uterine cervical epithelial tumors.

- Elastofibroma is a rare benign tumor-like condition manifesting as firm and spherical mass with poorly circumscribed margins of fibroelastic tissue, occuring in the subscapular region or the chest wall of elderly persons.
It is not a true neoplasm but rather a reactive or degenerative process causing abnormal elastogenesis. It is unilateral in the majority of cases and the right side is affected more commonly than the left. We report a case of bilateral elastofibromas removed from both subscapular regions of a 73-year-old female farmer. She was presented with tender masses on the bilateral subscapular areas for seven years. Microscopically, it consisted of a mixture of intertwining broad eosinophilic collagen bundles and elastic fibers associated with a few fibroblasts and mature fat cells. The elastic fibers had a degenerated beaded appearance or were fragmented into serrated globules in a linear arrangement.

Abstract
PDF
- Benign cystic mesothelioma (BCM) is a rare mesothelial lesion that forms multicystic masses in the upper abdomen, pelvis and retroperitoneum. Although it is categorized as a benign lesion, it has a tendency to recur. It is uncertain whether the nature of this lesion is reactive or neoplastic, but many articles support the conclusion that it is reactive rather than neoplastic. The majority of cases were associated with a history of a previous abdominal or pelvic operation, or an evidence of endometriosis or a pelvic inflammatory disease, or a combination of these findings. In a 26-year-old woman we experienced a case of BCM which was incidentally discovered at cesarean delivery revealing multilocular thin and translucent walled cysts in the pelvic cavity. Microscopic examination revealed a thin cyst wall that was composed of fibrous connective tissue and lined by internal stratified and external nonstratified single cuboidal epithelia.
