The Enchondroma is a benign cartilage forming harmartoma arising chiefly from short tubular bones on hands and feet. If on a long tubular bone or flat bone such as femur or ilium, it is most likely to be a true neoplasm such as chondrosarcoma, not a harmartoma. A case of enchondroma was reported. It occurred over right ischium of 19 years old male and was found incidentally by roentgenogram. The lesion was biopsied and diagnos's was confirmed by histologic examination. It was treated by curretage with filling of cavity with bone chips. Post operative-course was uneventful.

BACKGROUND: The Fas antigen is a cell surface molecule that mediates apoptosis in many cell types. Matsues group indicated that keratinocytes constitutively express the Fas antigen and apoptosis was induced only on pretreatment with interferon-r (IFN-y) in cultured normal human keratinocytes (NHK). OBJECTIVE: We undertook this study to determine the induction of apoptosis by Fas antibody alone and/or in combination with IFN y, IL-1a in normal human keratinocytes (NHK) and transitional epithelioma cell lines (KB cell) which had lower levels of intracellular IL-1 receptor antago- nists (IL-1ra ). METHODS: We used cultured NHK and KB cells. Each cell was treated with IFN-r, IL-la and Fas antibody for induction of apoptosis. For quantifying the apoptosis, index fluorescent DNA- binding dyes were used. Result: Fas antibody alone could induce apoptosis not only in KB cells but also in NHK cells. The combination of Fas antibody and IFN-r enhanced the induction of apoptosis in NHK and KB cells. The IL-la alone could induce apoptosis only in KB cells which had relatively small amounts of IL-1ra compared to NHK. CONCLUSION: Our result may indicate that Fas antigen in human keratinocytes can regulate normal epidermal cellular differentiation and proliferation.

Saccharomyces is an ascospore-producing yeast that is commonly employed in the brewery and bakery industries. We report a case of opportunistic skin infection with Saccharomyces in a 62-year-old female whose defense was impaired by immunosuppression. Previously reported cases have been treated with amphotericin B or ketoconazole and our patient respbnded to fluconazole.

In orper to measure the levels of high density lipoprotein cholesterol in psoriasis, 60 psoriatic patients and 30 healthy subjects were included in this study. Lopez-Virells methos was applied for measuring the serum level of high density lipoprotein cholesterol. The results were obtained as follows. The level of serurn HDL cholesterol was 58. 39+17. 40 mg/dl in psoratcs and 50.3+0.31 mg/dl in healthy subjects and 50. 43+ 10. 31 mg/dl in healthy subjects. No significant differences were noted between psoriatics & healthy subjects. 2. The level of serum HDL cholesterol was 56. 40+19. 10 mg/dl in male group of psoriatics and 60. 00+15.47 mg/dl in female group of psoriatics and 48.3+9. 50 mg/dl in healthy male group and 52.60 -10.59 mg/dl in healthy female group. No significant differences of serum HDL cholesteol levels were noted in both sexes.3. The mean value of serum HDL cholesterol by age groups of 10, 20, 30, 40, and 50 years old with psoriasis were 50. 70 mg/dl, 61. 97 mg/dl, 57. 44 mg/dl, 49. 11 mg/dl and 70. 36 mg/dl, respectively and those of healthy groups were 57. 25 mg/ dl, 45. 17 rng/dl, 50. 97 rng/dl, 48. 07 mg/dl and 46. 98 mg/dl, respectively.

Small cell carcinoma of the ovary is rare malignancy occurring in women under 40 years of age(average, 23 years), which is associated with hypercalcemia in two thirds of cases. Its histogenesis is uncertain, but the possibilities of common epithelial, neuroendocrine, sex cord stromal and germ cell origin are suggested. All reported cases were proved to have rapid fatal course despite various therapy and 5 years suvival rate was only 10%. We report one case of a 20-year old woman with primary small cell carcinoma of the left ovary. The ovary was markedly enlarged and completely replaced by a mass, measuring 21x16x8 cm. Microscopic examination revealed dimorphic population of small and large malignant cell producing immature follicle-like structure which is characteristic of small cell carcinoma of the ovary. These pathological findings were similar to those of granulosa cell tumor, which is required to make differential diagnosis from small cell carcinoma. Immunohistochemical stains for cytokeratin and vimentin were positive, but those for S-100 protein and NSE were negative. One month after the initial operation, the tumor has recurred and the second and the second palliative operation followed by 3 cycles of chemotherapy was done. The patient showed disseminated metastasis at present time.

A 48-year-old male patient had white to ivory colored patches on brown colored bases over the right side of his back for 8 years without accompanying pruritus or pain. Six months prior to the onset of his skin eruption, he received acupuncture for the relief of right sided back pain for 1 month. Histopathologic examination of the white patches showed follicular plugging, epidermal atrophy, focal hydropic degeneration of basal cells, lymphedema of papillary dermis, thickened homogenization of collagen fibers; consistent with findings previously reported in lichen sclerosus et atrophicus. We report this case to document the occurence in an acupuncture site and stress the unusual clinical manifestation of a zosteriform distribution.

BACKGROUND: Apoptosis is a highly selective form of cell suicide with characteristic morphologieal and biochemical features, including chromatin condensation, formation of apoptotic bodies, and DNA fragmentation by the activation of endonucleases. Various cytokines and physical or chemical factors can provoke apoptotic changes in the skin. OBJECTIVE: We investigated the cytotoxic effects with epidermal cytokines and their combinations, K+ ionophores, protein synthesis inhibitor(emetine), inhibitor of endogenous endonuclease(aurintricarboxylic acid, ATA), sodium azide, and retinoic acid witp human epithelial tumor cell lines(A431 cells) to examine the degree of induction of apoptosis in the epidermal keratinocytes. METHODS: Induction of apoptosis was measured in cultured human keratinocytes, keratinocyte cell lines(A-431, HaCat, KB cells), cultured human melanocytes and malignant melanoma cell lines(SK-28, SK-30) using a mixture of ethidium bromide and acridine orange, DNA agarose gel electrophoresis and TUNEL staining. RESULTS: l. In the A-431 cells, (1 to a certain degree, the combination of IFN-gamma and TNF-alpha could only induce apoptosis. Q2 most of K+ ionophores were observed to induce necrosis rather than apoptosis. Q3 emetine, a protein synthesis blocker, was found to induce apoptosis in a dose-dependent pattern. Q4 sodium azide at a concentration of 1% .induced apoptosis rather than necrosis. Q5 retinoic acid inhibit the beuvericin induced apoptosis. 2. In human keratinocytes, Ql more resistant in the induction of apoptosis than any cultured keratinocyte cell lines p aurintricarboxylic acid(ATA)-an endonuclease inhibitor, could inhibit UV induced apoptosis 3. In human keratinocytes and cultured keratinocyte cell lines, c-PAF inhibit the beauvericin induced apoptosis. 4. Human melanocytes is very resistant for the induction of apoptosis by beauvericin. 5. In the melanocytes and melanoma cell lines, sodium azide and beauvericin induced necrosis rather than apoptosis. CONCLUSIONS: The epidermis is continuously exposed to toxic factors which might induce cell death. With the above results, the induction of appeared to be rather resistant, epidermal cell apoptosis which may reflect the existence of some endogenous protective mechanisms in the epidermis to survive at certain toxic environments; melanocytes showed high expression of bcl-2 protein which could play a role in endogenous defense against toxic environments of the epidermis.
