Pseudoatrophoderma colli is a symptomless, persistent, persistent, pigmentary disorder involving the neck and upper thorax first described by Becker and Muir in. 1934 The lesion is usually localized to the neck and upper part of the thorax. It consists of macules or papules which show pigmentation or papules which show pigmentation or depigmentation and look atrophic. Histological examination shows hyperkeratosis, hypogranulosis, focal acanthosis and perivascular lymphocytic infiltration. We present herein a case of pseudoatrophoderma colli which showed symptomless, mottled, pigmentated macules involving the neck clinically and compatible findings histopathologically.

Routine use of commercially available antisera against hepatitis B core antigen(HBcAg) has permitted a reevaluation of the histochemical distribution of the antigen in liver tissue. HBcAg, classically described almost exclusively in the nucleus, was found with a very high frequency in the cytoplasm of liver cells as well. To elucidate the biologic significance of HBcAg expression and its relation to the natural course of hepatitis B virus(HBV) infection, the patterns of activity in 33 needle liver biopsies of HBsAg carriers were analysed. A good correlation of liver HBcAg with disease activity was demonstrated. HBcAg was present in the hepatocyte nuclei(nHBcAg) or cytoplasm(cHBcAg), or in both(mixed). Pure nHBcAg was seen mainly in non-aggressive reactive liver tissue and cHBcAg was predominantly associated with chronic active hepatitis(95%). The results suggest that expression of HBcAg correlates with the liver pathology and the possibility of HBcAg to be an immunological target for T cell mediated hepatocyte damage.

Soft tissue related complications are quite frequent in limb lengthening. Muscle fibers may proliferate or regenerate after stretching injury over 10-20% of their original length. However, the cells which are engaged in this phenomenon are not confirmed yet. We chased the S-phase cells (phase for DNA replication) in the posterior leg muscle during limb lengthening by immunohistochemical technique. We lengthened the tibiae of fifteen New Zealand white rabbits. We divided them into three groups and each group is consisted of five rabbits. In group 1, we lengthened the left tibiae by 10% of their original length, in Group 2, 20%, and in group, 3, 25%, respectively, At the end of lengthening posterior muscles of lengthened left side and of controlled right side were fixed and processed for Immunohistochemical staining which could detect the incorporation of bromodeoxyuridine(BDU). Labelling index(LI:% of positively stained S-phase nuclei) of group 1 was zero. LI of groups for more than 20% lengthening (sum of group 2 and 3) was statistically significant. In conclusion, nuclei around or within the muscle tissue are in S-phase during limb lengthening which means proliferation of the muscle fivers or of the certain cells that abut muscle fibers.

Average anteversion of the femur is 15.3 degree. Ultrasound, computerized tomogram, and three dimensional reconstruction from CT or MRI have been used for more accurate measurement of the anteversion. There are two methods in measuing anteversion angle from CT scan:one is by drawing a mid line through long axis of the femoral neck (conventional method). Another is by drawing a line from the center of the head to that of the neck at the base of the trochanter using several cut slices (Murphy’s method). We compared these methods with fluoroscopic measurement of the Anteversion. We traced the change of the anteversion before and after closed femoral intramedullary (IMO) nailing to evaluate the origin of malrotation of the femur. 1. Normal anteversion angles were measured in 15 cases. Average anteversion angle was 6.9 degrees by conventional method, 12.3 degrees by Murphy’s method, and 12.2 degrees by fluoroscope. 2. Anteversion angles were measured after IM nailing in 18 cases. Average was 17 degrees by Murphy’s method and 15.2 degrees by fluoroscope. Mean of difference between these two methods sea 6.3 degrees. That was 1.7 degrees in normal side. 3. Change of the anteversion angle between before and after IM nailing was measured in 17 cases by fluoroscope. Average anteversion angle before the operation was 11.9 degrees and it was change to 15.8 degrees after operation. Mean of these change was 7.1 degrees. 4. Pereperative traction provides important information on change of anteversion. Reduction excessive flexion of proximal fragment was a origin of change of anteversion during nailing procedure. Conclusion : Malrotation of the femur after IM nailing must be keep in mind and it may be preventable by fluoroscopic control of the rotation in nailing procedure.

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.

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.
