 Abstract

- We evaluated the availability of toluidine blue stain in body fluids, such as peritoneal and pleural fluid and urine. Nine hundreds specimens, i.e., 400 pleural and 400 peritoneal fluids and 100 urine samples, respectively, from Jan. 1995 to May 1996 were included. We obtained the result of high sensitivity and high specificity in toluidine blue stained body fluid in comparison with Papanicolaou stained result.
Additionally, we found the diagnostically important crystals in chylothorax and some urine samples, which can not be seen in routine Papanicolaou stain. We thought the toluidine blue stain in body fluid is one of very useful diagnostic methods.

Abstract
PDF
- To evaluate the incidence and clinico-pathologic correlation of benign epithelial changes of endometrium, we tried to classify the changes into squamous cell change, ciliary change, eosinophilic cell change, papillary surface epithelial change, and mucinous cell change by the criteria of Hendrickson. Based on the 450 hysterectomy specimens obtained from Jan. 1994 to Dec. 1994 in PMC, the incidence of the cell changes was as follows: squamous cell change: 1.1%, eosinophilic cell change: 6.8%, mucinous cell change: 6.6%, ciliary change: 10.4%, papillary surface epithelial change: 16.4%. Squamous cell change was noted in severe endometritis or endometrial hyperplasia and papillary surface epithelial proliferation was mainly associated with plasma cell infiltration in adenomyosis or leiomyoma.
Eosinophilic change and ciliary change were sometimes concomitantly found in dilated glands of the basal layer or in the invaded glands of adenomyosis. The results of this study suggested a correlation of benign epithelial changes with endometritis, adenomyosis, leiomyoma and dysfunctional uterine bleeding.

Abstract
PDF
- Although exfoliative colonic cytology for the diagnosis of colorectal cancer has been largely abandoned due to the widespread use of colonoscopy, some authors still insiston the usefulness of colon lavage fluid. We tried evaluating the diagnostic feasibility of colon lavage fluid cytology using an orally administered balanced electrolyte solution.
We collected colon lavage fluids in 106 patients prior to colonoscopy and reviewed the slides. Cytologic examination revealed neoplastic cells in 7 of 16(44%) cases of endoscopically proven adenocarcinoma patients. Therefore, we think cytologic study of colon lavage fluid may be considered as one of the noninvasive diagnostic tools in colorectal cancer.

Abstract

- Angiomyofibroblastoma of the vulva is a rare mesenchymal tumor. It has been diagnostically confused with aggressive angiomyxoma which has a somewhat different clinical course and therapy. Herein we report a case of angiomyofibroblastoma of the vulva in a 46-year-old female.
Microscopically, there were alternating hypercellular and hypocelluar edematous zones in which abundant capillary blood vessels were irregularly distributed. Spindle, plump spindle, and oval stromal cells were concentrated around the blood vessels, or loosely dispersed in the hypocellular area. Immunohistochemically, the stromal cells were positive for desmin, vimentin, muscle-specific actin and weakly positive for S-100 protein. Ultrastructural studies showed well developed rough endoplasmic reticulum, abundant intermediate filaments, and pinocytic vesicles in the stromal cells.
