Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently introduced automated biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4 (11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5(1-5) We concluded that US-guided gun biopsy was a easy and safe way to obtained tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialists in cytopathology.

We present four cases of herpes zoster treated successfully with vidarabine-5-monophosphate, two patients receiving chernotherapy and radiation therapy due to Hodgkins lymphoma or colon cancer, a patient combined with viral meningitis, and a patient with herpes zoster ophthalmicus. Viclarabine can be used to treat herpes zoster in immunosuppressed patients or patients with malignancy or patients with severe complications.

A case of complete loss of penile skin treated with scrotal skin graft was presented in a 26 year old male. This case was noted to be a complete loss of penile skin which was developed under local anesthesia with formalin 30 cc during circumcision. The implantation of the penis in the scrotum was performed by the scrotal tunnel method. Complete logs of penile skin was restored by implanting the denuded surface under the subcutaneous tissue of the scrotum.

Korean Journal of Dermatology 1987;25(5):629-632
We observed a 51-year-old male, who developed depigmented patches on the lower abdomen after photochemotherapy(PUVA) of psoriasis without evidence of phototoxic reaction. The depigmented patches did not orginate from the sites of previous psoriatic lesions. Fontana-Masson stain of the biopsy specimen revealed nearly absent melanin pigments in the epidrmis of the hypopigmented patch, while lots of pigments were obsereved on the surrounding hyperpigmented area. Electron micrograph showed no melanocytes in the hypopigmented patch. Thus we report this case as having vitiliginous patches induced by photochemotherapy of psoriasis.

Nitric oxide ( NO ) is now recognized as a mediator of several biological and immunological functions, but unlike classical neurotransmitters, NO simply diffuse of the postsynaptic cell and around affecting cells. Human chorionic gonadotropin ( hCG ), produced by placental trophoblasts may act as stimulator on NO synthesis in oocytes of mouse's ovary. How-ever, in the various organs or cells, the action of hCG on NO synthesis is unknown. We have examined that the effect of hCG on NO synthesis in microglial cells of murine's brain, using the Griess method. And this study was evident that hCG did not induce NO produc-tion without recombinant interferon gamma ( rIFN-gamma), whereas hCG ( 10~500 IU/ml ) with rIFN-gamma effectively produced NO in microglial cells of brain. As result, NO production in microglial cells increased most significantly in dose of 100 IU/ml of the hCG and the pro-duction of NO was dependent on the dose of hCG ( Table 1 and Fig. 1 ). And N(G)-monomethyl-L-arginine ( N(G)MMA ), competitive inhibitor of NO synthase, reduced the NO production by hCG stimulation with rIFN-gamma in microglial cells of murine. Conclusively, this study sugge-sted that hCG stimulate NO production at microglial cells in brain, which may be an important factor for mediating immune and neuroendocrinologic regulation in nervous system.

Brodie's abscess is a primary subacute pyogenic osteomyelitis that has a thin wall of fibrous tissue and sclerotic bone. The authors have encountered a case of a Brodie's abscess that was developed in the same place of both tibia at the same time and treated the case with surgery and continuous closed irrigation.

PURPOSE: To evaluate the frequently of low ahetenuation area in enhanced CT scans of non-Hodgkin lymphoma(NHL) and to find out if there is any pertinent relationship between this and the histopathologic classification. MATERIALS & METHODS: The authors reviewed CT scans in the newly diagnosed 53 patients with NHL. We defined the-low attenuation area as the one with CT attenuation value lower than that of the muscle, surrounding lesion, or other lymph nodes after contrast enhancement. NHL with the low attenuation areas were correlated with the histopathologic findings according to the classification based on the Working Formulation and the frequency of the lesion was evaluated. RESULT: Of the 53 patients, the low attenuation area was found in 13 patients (25%) at CT. The histopathologic classification could be made in 12 patients, among whom one patient was classified as low grade, six as intermediate grade, and five as high-grade. Concerning the specific cell typing, the diffuse large cell type was most common in intermediate-grade NHL seen in five patients and the large cell, immunoblastic type was most common in high-grade NHL seen ih three patients. CONCLUSION: The authors concluded that the low attenution area within lymphoma is not an infrequent finding at CT, and there was no stastistically significant correlation between this finding and the prognostic grading of the Working Formulation.

PURPOSE: To evaluate the usefulness, patterns and appearances of false positive lesions, and technical problems of CTAP(CT Arterioportography). MATERIALS AND METHODS: CTAP was done in 45 patients in whom hepatic lesions were suggested on other radiologic studies. CTAP findings were compared with the informations obtained by operations, biopsies, and follow-up imagings. Additional findings, which were not detected in other radiologic studies, false positive manifestations, and technical errors were analyzed. RESULTS: CTAP detected 51 additional hepatic lesions which are not detected in other imaging studies. Of the 51 lesions, ten were true positive hepatic tumors, 2 were inflammatory lesions and 39 were false positive .lesions. False positive lesions included perfusion defects of periportal and perifissural areas, subcapsular perfusion defects and nonlobar, nonsegmental geographic perfusion defects. In 2 cases, CTAP aided in deciding the surgical strategy. On the other hand, there were 4 cases causing interpretational confusion and 6 cases of improper imaging due to technical errors. CONCLUSION: CTAP was valuable in detection of additional hepatic cancer lesion as well as in making the treatment plan. However, since many false positive lesions and improper imaging due to technical error occur during the examination, the understanding of such problems is essential for correct interpretation of CTAP.
