A 49-year old man was admitted to the Korea university hospital, department of surgery, for evaluation of anterior neck mass which was slowly growing for five years. His past history was unremarkable except for known hypertension for several years. Physical examination revealed high blood pressure, measuring 180 mmHg in systolic phase and 120 mmHg in diastolic phase. A soft nontender mass was palpated at anterior neck just above the sternal notch with smooth surface and its size was about 4 x 5 cm in cross. On laboratory examination, diabetic evidence such as high blood sugar (FBS 170 mg/dl, PP2hr. 234 mg/dl) and glucosuria. The CBC finding suggested polycythemia with high hemoglobin (18.0 g/dl) and hematocrit (54%) levels. The differential count and platelet count were within normal limits.

A case of Vogt-Koyanagi-Harada's Sindrome chiefly affected the anterior uvea has been clinically studied with several references. It was a typical one with hearing disturbances and was complicated with a secondary glaucoma. Following the iridectomy the I.O.P. was back to normal limit and with steroid therapy the inflammatory signs were relieved. After a considerabie period the anterior uveitis recurred. In this case the age of the patient was 10 years older than those Parker presented.

Lymphangioleiomyomatosis(LAM) is a rare disease of women of child-bearing age in which there is progressive hyperplasia of atypical smooth mucle along lymphatics in the lung, and/or axial lymphatics in the thorax and abdomen, resulting in honeycombing of lung. Interestingly there has been a speculation that it represents a forme furste or incomplete expression of tuberous sclerosis complex. This is based on the observation that patients with tuberous sclerosis can manifest pulmonary lesions indistinguishable from LAM. We report a case of LAM occuring in a 39-year-old female, who complained of recurrent pneumothorax, chest pain and shortness of breath. Three years ago, the patient had right nephrectomy under the diagnosis of ruptured angiomyolipoma. A X-ray film of the chest showed honeycombing with a diffusely reticulonodular pattern and cyst-like spaces. She had a characteristic facial appearance of adenoma sebaceum, which her father and uncle had. Microscopically, the lung showed a marked smooth muscle proliferation around the slit-like lymphatic spaces and also some respiratory bronchioles.

A defective HIV-1 helper virus DNA, pHyPC, was assembled by deleting the RNA packaging signal, env, nef and the 3'LTR sequences. HIV-1 like virus particles that carry the HIV-1 receptor, CD4 were generated by coexpression of pHyPC and plasmid DNAs encoding different chimeric CD4 proteins. The CD4 particles, sharing the CD4 ectodomain, precisely fused to different membrane anchors. CD4(+) particles specifically bound to HIV-1 Env expressing cells, but any signs of infection into these cells were not detected. Binding was only partially blocked by either polyclonal anti-CD4 antibodies or by high concentrations of soluble CD4. Suprisingly, CD4(+) particles also adsorbed to HeLa, CHO, NIH3T3 and COS-7 cells in the absence of HIV-1 Env expression. Adsorption was comparable in strength and speed to the highly specific CD4-Env interaction. CD4(-) particles exhibited only background levels of binding. Cell binding was CD4- dependent, but it was independent of the cell type from which the CD4(+) particles originated. Interestingly, CD4-dependent/Env-independent binding was only found when CD4 was present on virus particles. This suggests that the micro-environment of CD4 on virus particles uniquely expose this new cell binding activity. Its high affinity could explain in part why infection of Env(+) cells by CD4(+) particles was not detected. Further experiments will be required to evlauate whether this strong membrane interaction could represent one step in the multiple-step viral entry process.

Fibroepithelial polyps of the ureter are usually acquired rather than congenital. Most polyps are hamartomatous growths which tend to arise in the proximal portion of the left ureter. Most patients exibit either hematuria or persistent flank pain secondary to partial ureteral obstruction. Because of false positivity of urine cytology, as well as intravenous pyelogram, the correct diagnosis is confused with malignancy. Herein we report four cases of ureteral fibroepithelial polyp, which are associated with stones resulting in partial obstruction of the ureter. One of the four cases is associated with nephrogenic adenoma in the lamina propria of the adjacent ureter. The following report describes clinicopathologic findings of fibroepithelial polyp with review of literatures.

POEMS syndrome is an unusual plasma cell dyscrasia with multisystemie manifestations featuring polyneuropathy, organomegaly, endocrinopsthy, M protein and skin changes. We have seen a 49-year-old woman presenting with hyperpigmentation, hypertrichosis, hyperhidrosis, and taut thickened skin of the extremities as a skin manifestation of this syndrome. We review the literature and report a case.

8.Fabry's Disease: A case report of electronmicroscopy and enzyme studies.

Fabry's disease is a rare hereditary metabolic disease caused by alpha-galactosidase deficiency, resulting in abnormal accumulation of galactosyl galactosyl galactosyl ceramide (ceramide trihexoside) in various organs. Articles in English reported approximately one hundred cases but only two cases in Korea. Recently the authors experienced a case of Fabry's disease of a male patient and studied the electronmicroscopy on skin biopsied tissue and enzyme assay of alpha -galactosidase activity in his peripheral blood leukocytes. The male patient was a 21-year-old soldier who suffered from anhidrosis with heat intolerance and generalized telangietatic papules (Angiokeratoma corporis diffusum) since childhood. Other clinical findings were ocular change, paroxysmal pain of lower extremities and proteinuria with oval fat bodies on urinalysis. The ultrastructural study of skin demonstrated abnormal lysosomal deposits of finger-prints or "zebra" body configuration in the endothelial cells, pericytes, perineural cells and intercalated ductal epithelium of sweat glands. Enzyme activity of alpha-galactosidase was markedly decreased in the peripheral blood leukocytes comparing to the normal control, which was conclusive to make a diagnosis of Fabry's disease.

Nowday, ionizing radiation is one of the methods eradicating the uterine cervical malignancy. However radiation alone or in combination with surgery have an effect on normal tissue as well as the malignant cells, and their changes have been well described in other countries. Unfortunately, the history of radiation modality for cancer treatment is relatively short and the reports about radiation induced changes are limited in our country. We evaluated the radiation-induced changes in cervico-vaginal smears of 107 uterine cervical cancer patients obtained from March, 1985 to October, 1987. Most patients had been received 5,400 Rads of external radiation and intracavitary radiation. Patient's age ranged from 30 to 67 years old. Of 107 cases, 24 cases were normal, 72 cases showed benign radiation changes, 7 cases revealed radiation dysplasia, and residual and recurrent carcinomas found in one and 3 cases, respectively. Cytoplasmic and nuclear enlargement were the most common and noted in 57 and 38 cases, respectively. Vacuolization and polychromasia of the cytoplasm were identified in 43 and 30 cases, respectively. The most common histiocytic change was multinucleation, which was found in about one third. The radiation changes of the cytoplasm and nuclear enlargement persisted for a long time after completion of radiation, however, nuclear degeneration and multinucleation gradually disappeared after 6 months. The inflammation in background prolonged for a long time but degeneration disappeared after 6 months. The biologic significance of post-radiation dysplasia could not evaluated because of short follow up period.
