Mycobacteriosis cutis is largely classified to localized forms and exanthematous forms and it is subdivded into five diseases in detail, each. They are 1) primary tuberculous complex, 2) lupus vulgaris, 3) tuberculous verrucosa cutis 4) scrofulo derma, and 5) tuberculosis cutis orificialis in localized ferms and 1) tuberculous miliaris disseminata, 2) lupus miliaris disserninaia faciei, 3) papulonecrotic tuberculid, 4) lichen scrofulosorom and 5) ervthema induratum in exanthematous forms.Rich(1944) insisted on that, the pathogenesis of cutaneous tuberuculosis was essen tially the sarne as that for tuberculosis in general. He said that aII forms of cutaneous tuberculosis were produced by the local action of the bacilus of tuberculosis. In the formerly termed true tuberculosis such as lupus vulgaris, the microorganisrns were found in varing numbers in the lesions, and animal inoculations of tissue were successful, In other forms represented by the tuberculids, the bacillus of tuberculosis was found only in the earilest stages before the true clinical and histological picture had developed, Its short lived existence in this forms was explained by the allergic statc of the tissues and this fact exnlained the failure to find the microorganisms in the lesions, or reproduced the affection by inoculations in animals, in cases sufficiently developed to be recognizable clinically and histologically. The other generally accepted view is that the mycobacteriosis cutis, especially the types in the category of tuberculids are caused by the hematogenous dissemination of tubercle bacilli from a focus, often extrapulmonary in location, into the skin, where they are rapidly destoryed. spiet and Roeckie(1960) agreed with above menitioned plausible theories with the background of their hypothesis, that was the skin was hyperegic, And Miescher(1951) also insisted that, skin had a decreased immunologic resistance. But according to Flegel(1957), if the skin was in a state of hyperegic reaction, the focus from which the dissemination was taking place was also should be in a hyperegic state and vice versa should be right, And moreover, Suizberger(1940) declared that whenever microorganisms or their products were being overcome or neutralized by local lmmunologic reactions, tubercles or tubercles or tuberculoid structures had a tendency to appear. So the theories of different immunologic state between the skin and focus were discarded. After that many authors proposed three factors against a tuberculous etiology of tuberculids. First, inoculation of tissue from lesion into guinea pigs and culturing of such tissue have given no evidence for tuberculosis. Second, active tuberculosis occurs no greater frequency in patients with tuberculids than in the general population. Third, tuberculids does not respond to antituberculous treatment but responds to the adminiatration of corticosteroids. According to Eberhartinger(1963), Schneider and Undeutsch(1965), in erytbema induraturn the primary event is a vasculitis of subcutaneous arteries and veins. And any fat necrosis following vascular damage can develop a tubereuloid appea- rance. Lever(1967) declared with self confidence that it was a relic of the times- when a tuberculoid histology was tantamount to tuberculosis. In this condition we decided to clarify that whether the mycobacteriosis cutis, especially the disease in the category of tuberculids, could be originated from mycobacteria tuberculosis in fact or not. Eleven patients, whose clinical diagnosis were skin tuberculosis or very similar to those diseases such as erythema. nodosum, were biopsied by 5mm puncher after 2% procaine injection on their two of skin lesions, the early one for the culture of tubercle bacilli and the oId one for histopathological study, on the O.P.D. of dermatologic department in Severance Hospital. Those biopsied material of early lesion was digested with proper amount of 4% NaOH and fragmented in tissue grinder about 10 minutes. After that, it was centrifuged in rotating speed of 3,500 r.p.m. for 30minutes, and neutralized by 8% HCl after adding phenol red drop by drop. Again it was centrifuged by same as previous method and its supernatant was discarded. The remnants of precipitin was inoculated on Ogawa's nutrient tuberculous media in incubator at 37C. Finally the acid-fast tubercle bacilli have been grown on the Ogawa's media three months after its first inoculation. The inoculation material was biopsied from the patient of eighteen year-old girl, whose clinical and histopathological diagnosis was erythema induratum. From the result of this study, we got the strong confidence that in spite of many authors powerful countertheories and the extremely poor harvesting of its culture, the erythema induratum can be or in evidently caused from mycobacterium tuberculosis. It may be early days yet to say that erythema induratum is originated fromtubercle bacilli but it is considered to be a truth in Korea, with the result of this study.

A case of malignant melanoma developed from giant congenital pigmented nevus in a seven year old girl was reported. Since the identification of benign juvenile melanoma, the distinct rarity of true cutaneous malignant melanoma in infants and children has become generally recognized. In giant congenital pigmented nevus, the malignant melanoma as a rule arises deep in the dermis. In this case, the histopathologic finding shows no junctional activity in epidermodermal juction other than ordinary nevocellular nevi, but some nevus cell nests and mild inflammatary cell infiltration in the upper dermis. And in the deep dermis, well marginated but not encapsuIated huge tumor mass, in which variable sized, pleomorphic, several vigorous mitotic figures in predominantly cuboidal cells and bizarre giant cells, which was thought to be developed from giant congenital pigmented nevus. The few recorded cases of fatal cutaneous malignant melanoma in early life are of two types: those arising in giant congenital pigmented nevi and ordinary small nevi, de novo including small nevus. The former account for between 22% and 40% of the total. This case is one of the reported 20 cases in the world.

The clinical findings in the Vogt-Koyanagi-Harada syndrome ae reviewed and eight cases reported emphasizing the cutaneaus changes. The syndrome consists of symptoms of poliosis, vitiligo, alopecia, meningeal irritation sign, nontraumatic uveitis, and dysacousia. Meningeal or ocular symptons usually appear first, but in some patients thc cutanious changes have been observed beforc the uveitis. The etiology rernains unsettied, but an allergic mechanism or a virus infection is favaveci by most observers. Early diagnosis is important because ocular mobidity can be reduced significantly in some patients if treated in the early stages. During the course of treatment of our patients, corticosteroid is appeared to be the most effective drug for this uncertain etiologic syndrome and this fact may eventually support. the theory nf autoimmue mechanisn. The daily does of corticosteroid is prednisolone 60mg and the duration of administration is from 15 days to 2 months, after that the dose is graclually decreased in relation with the degree of symptoms. The ophthalrnologic symptoms were markedly improved 10 days after the administvation of prednisolonc. The purpose of this report is to emphasize the cutaneous findings in this syndrome, to point out that the cutaneous manifestations may lead to establishing tne diagnosis and on the basis of that, those patients can be received prompt, suitable treatment to avoid the grave ocular morbidity.

Clear cell chondrosarcoma, first described by Unni in 1976, is distinguished from classical chondrosarcoma by a typical histological picture, mostly an epiphyseal site of origin, and relatively a benign clinical course. We present a case of clear cell chondrosarcoma arising from hyoid bone in a 70-year-old male. Histologically, large areas of closely packed cells with characteristic clear cytoplasm were seen in addition to the usual elements of a conventional chondrosarcoma. Our search and review of the literature did not reveal any reported case of clear cell chondrosarcoma arising from hyoid bone.

PURPOSE: To assess the value of gray-scale stimulated acoustic emission in differential diagnosis between hepatocellular carcinoma and metastatic adenocarcinoma. MATERIALS AND METHODS: Twenty-four cases of epatocellular carcinoma (HCC) in 23 patients and 26 cases of metastatic adenocarcinoma in 14 patients were prospectively examined using the pulse-inversion harmonic technique after intravenous SH U 508A administration. Gray-scale stimulated acoustic emission (SAE) was measured 5 mins after bolus injection of a contrast agent (4g, 400 mg/ml). The presence or absence of SAE signals at internal and marginal areas of the tumor and the appearance (smooth or irregular) of its border were compared. In addition, the SAE index [SAE (parenchyma) - SAE (tumor)/ SAE (parenchyma)] was histographically determined using a computerized program (PiView TM ; Mediface, Seoul, Korea). The statistics were analysed using student'st test. RESULT: Of the 24 HCC cases, 20 (83%) showed internal SAE signals, while 23 (96%) marginal signals were emitted. Of the 26 cases of metastatic adenocarcinoma, one (4%) showed internal SAE signals, while in five (19%), these signals were marginal. The tumoral border was irregular in 19 HCC lesions (79%) and smooth in 23 metastatic lesions (88%). For HCC and metastatic tumors, the mean SAE index was 0.38 +/-0.15 and 0.60 +/- 0.08, respectively (p < 0.001). CONCLUSION: Gray-scale stimulated acoustic emission can be a useful tool in differential diagnosis between heatocellular carcinoma and metastatic adenocarcinoma.

Shikonin, which derives from Lithospermum erythrorhizon, has been traditionally used against a variety of diseases, including cancer, in Eastern Asia. Here we determined that shikonin inhibits proliferation of gastric cancer cells by inducing apoptosis. Shikonin's biological activity was validated by observing cell viability, caspase 3 activity, reactive oxygen species (ROS) generation, and apoptotic marker expressions in AGS stomach cancer cells. The concentration range of shikonin was 35–250 nM with the incubation time of 6 h. Protein levels of Nrf2 and p53 were evaluated by western blotting and confirmed by real-time PCR. Our results revealed that shikonin induced the generation of ROS as well as caspase 3-dependent apoptosis. c-Jun-N-terminal kinases (JNK) activity was significantly elevated in shikonin-treated cells, thereby linking JNK to apoptosis. Furthermore, our results revealed that shikonin induced p53 expression but repressed Nrf2 expression. Moreover, our results suggested that there may be a co-regulation between p53 and Nrf2, in which transfection with siNrf2 induced the p53 expression. We demonstrated for the first time that shikonin activated cell apoptosis in AGS cells via caspase 3- and JNK-dependent pathways, as well as through the p53-Nrf2 mediated signal pathway. Our study validates in partly the contribution of shikonin as a new therapeutic approaches/ agent for cancer chemotherapy.
