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.

STUDY DESIGN: A case report. OBJECTIVES: To report a rare case of cauda equina syndrome due to lumbar ossification of the posterior longitudinal ligament (OPLL). SUMMARY OF LITERATURE REVIEW: Lumbar OPLL with neurologic symptoms is very rare. MATERIALS AND METHODS: A 49-year-old female had experienced weakness in both lower extremities and radiating pain for 1 day prior to presentation. Simple radiography and CT showed OPLL at the L1-L2 level. We performed a total laminectomy and posterolateral fusion at the L1-L2 level using a posterior approach. RESULTS: After treatment, the patient showed improvement of symptoms and is currently living without discomfort. CONCLUSIONS: Cauda equina syndrome due to lumbar OPLL is rare; however, rapid neurologic recovery can be achieved through early diagnosis and surgery.

Intra-abdominal desmoplastic small round cell tumor has been described in the literature since 1989. It is characterized by the occurrence in ages less than 40 with male predominance, an intra-abdominal location, and small round to oval shaped tumor cells with divergent differentiation in the background of the desmoplastic stroma. We recently experienced this tumor in an inguinal lymph node of a 36-year-old man. It is suspected that it metastasized from a lower intra-abdominal tumor. Immunohistochemical stains for keratin, epithelial membrane antigen, vimentin, S-100 protein and neuron specific enolase were positive. This is the first documented case in Korea. Herein, we report on this tumor with a review of literature.

CD44, also known as the Hermes antigen, H-CAM, pgp-1 antigen, and extracellular matrix receptor ECM-III, is a widely distributed integral membrane protein that exists in a variety of forms with different molecular sizes ranging from 85kd to 160kd. A number of evidence implicates CD44 as a cell adhesion molecule with a possible role in tumor progression. To evaluate the possible roles of CD44 in the metastatic process of gastric carcinoma to the regional lymph nodes, we applicated immunohistochemical stains with the CD44H and CD44v6 primary antibodies onto the 2 groups of gastric adenocarcinomas. Each group was comprised of 22 primary tumors extending to the subserosa, and one group showed nodal metastasis, while the other group did not. Seventeen primary tumors (77%) out of the 22 cases with the nodal metastasis demonstrated positivity to the CD44v6, while only 9 primary tumors (41%) out of the 22 cases without nodal metastasis did. However CD44H immunoreactivity was demonstrated in tumor cells of all cases (100%) of both groups as well as in the normal cell components. These results suggest that CD44H form is not related to the metastasis to the regional lymph nodes of gastric carcinoma. However, the expression of CD44v6 seems to play a certain role in the metastatic process of the gastric carcinoma.
