Trichoepithelioma, a tumor of the hair follicle, is usually seen as multiple lesions, but occasionally appears as a single tumor. Multiple trichoepithelioma is a dominant hereditary skin conditions whereas solitary trichoepithelioma is not hereditary and is growing tumor, usually seen in adults. A case of 56 year old housewife with solitary trichoepithelioma was reported. The skin lesion appeased as a firm, skin colored papule and the size was 0.5cm in diameter on right side of nose. Shaving biopsy was done and showed a high degree of differentiation toward hair structure and horn cyst that the keratinization is abrupt and complete. The methood of treatment is a surgical excision and electrodesiccation but remain a scar due to surgical trauma. And so, we used a 5-fluorouracil ointment instead of surgical excision and electrodesiccation, The skin lesion on nose was cured completely as a result of 5-FU ointment application without any scar formation cosmetically.

The nodular vasculitis described by Montgomery on 1945 and is characterized by relatively chronic, persistent, or recurrent nodular lesions of nontuberculous origin chiefly on the legs. In the differential diagnosis the following must also be considered; erythema induratum, eythema nodosum, Weber-Christian disease, erythema nodosum migrans, recurrent thrombophrebitis and periarteritis nodosa. The authors observed one case of nodular vasculitis caused by sulfa drug. This patient was diagnosed to papulonecrotic tuberculid at first and treated by prednisolone 20 mg, INH 300 mg and streptomycin l.0 gm BIW. By the treatment, the patient, was cured completly within 3 months but visited again because of recurrence after 6 months. Therefore, same medication was given, but did not show improvment and added sulfa drug, Lederkyne. But, unfortunately the skin lesions was aggrevated after sulfa medication. It was suggestive that the cause of aggrevation was sulfa drug and discontinued the sulfa drug. The skin lesions were completely cured after the drug was discontinued.

The authers observed one case of typical poikilodermatomyositis who was 47 year old female. The poikiIodermatomyositis is a rare disease which is a variant of dermatomyositis and has never been reported in Korea. This patient complained of a weakness of left lower leg and tingling sensation of both fingers since one year ago, And she has a difficulty of both finger flexion since 20 days ago. The skin lesions revealed mottled dark brownish pigmentation, hardness, scattered atrophic patches and telangiectasia in the lesion on the left lower leg since one year ago. The same skin changes appeared on the thigh, lower abdomen and upper chest on 4 months ago. Histopathologically, a biopsy was performed from the skin of lower leg, the skin shows typical poikiloderma, i.e. the epidermis shows moderate atrophy of the stratum malpighii, flattened rete ridges and hydropic degeneration of the hasal cells. The dermis is edematous and a band like dense lymphocytic cellular infiltration. And the muscIe biopsy from gastrocnemius muscle shows dermatomyositis finding which the muscle bundles are edematous and degenerative. Many inflammatory cells present between muscle bundles but there is no suppurative change. Diagnosis was confirmed by clinical appearance, histopathologically and other laboratory studies. The patient was markedly improved by the prednisolone 80 mg and vasculat (vascular dilatator) 100 mg daily.

We studied 193 Diabetics without any symptoms of coronary artery disease and 39 Normal healthy subjects as Control group, using treadmill exercise test and obtained following results. 1) The positive rate was significantly higher in Diabetics(19.4% in Normal ECG groups and 25.4% in total Diabetics)than Control groups(5.1%)(0.010.05). 5) There was no difference in HbAIC, Total cholesterol and Triglyceride between positive and negative groups(P>0.05). In summary, with exercise test, the positive rate was higher in Diabetics than in Normal control groups and it seemed to be treadmill exercise test is a useful screening method for evaluation of coronary artery disease as well as for assesment of treatment and follow up care.

Reiters syndrome is an unusual disease characterized a triad of nongonococcal urethritis, conjunctivitis, and arthritis in association with the mircoutaneous lesions of keratoderma blenorrhagica and balarintis circinata. We present herein a case of Reiters syndome combined yiti lung cancer. A 39-year-old man has experienced naigrating polyarthralgia and high fever ilitermittently for about 20 years, Hyperkeratotic erythemnous patches and plaques, which dyeliped about 1 year ago, have aggravated and expanded to the whole body. Histopathologic sections from the plaque on the right forc ari showed characteristic findings including thickened parakeratotic horny layer and spongiform micropustules of Kogoji He was associated with HLA-B27. On the chest X-ray, a thumbtip size mass was incidently found. Chest CT and bone scan findings supported lung cancer and multiele metastases.

BACKGROUND: Puromycin aminonucleoside (PAN) is a known podocytotoxin. PAN-induced nephrosis is a widely used animal model for studying human idiopathic nephrotic syndrome. Abnormal protein accumulation associated with podocyte-specific endoplasmic reticulum (ER) stress damages cells structurally and functionally, which in turn induces apoptosis and severe proteinuria. In the present study, we investigated the effect of PAN on ER stress and apoptosis in podocytes in vitro. METHODS: Mouse podocytes were cultured and treated with various concentrations of PAN. ER stress markers were then evaluated by western blotting, and apoptosis was evaluated by fluorescence-activated cell sorting (FACS) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays. RESULTS: PAN treatment increased ER stress markers such as activating transcription factor (ATF) 6α and caspase-12 in a dose-dependent manner at 12 and 24 hours, respectively. These markers were reduced by chemical chaperones, such as sodium 4-phenylbutyric acid and tauroursodeoxycholic acid. PAN treatment also increased 78 kD glucose-regulated protein (GRP78)/binding immunoglobulin protein (BiP) at the earlier stage of 12 hours. PAN significantly induced podocyte apoptosis in concentration- and time-dependent manners, as seen using FACS and TUNEL assays. This result was improved by Nox4 siRNA, ATF6 siRNA, and chemical chaperones. LY294002, a PI3-kinase inhibitor, significantly boosted ER stress and apoptosis. PAN-induced ER stress increased oxidative stress and subsequently induced apoptosis, and could be mitigated by inhibition of PI3-kinase signaling. CONCLUSION: Our findings suggest that PAN induces ER stress in podocytes mainly through the GRP78/BiP, ATF6α, and caspase-12 pathways, which trigger apoptosis via induction of oxidative stress. This stress is mitigated by inhibiting PI3-kinase signaling.

OBJECTIVE: To evaluate the perinatal prognosis of fetuses with a single umbilical artery. METHODS: From 1992 to 1998, nineteen cases with single umbilical artery(SUA) was observed in 8,704 deliveries at Chonnam University Hospital. RESULTS: Out of nineteen fetuses, thirteen fetuses with single umbilical artery were detected by antenatal ultrasonographic examination and six fetuses were detected after birth. The male to female ratio was 0.9: 1. Congenital malformations were observed in 8 babies(42.1%) and included leg deformity, esophageal atresia, imperforated anus, ventriculomegaly, meningocele, hydronephrosis, ventricular septal defect, joint contracture, cleft lip and palate, toe anomaly, imperforated anus, kyphosis, no urethra and testis, clubfoot, patent ductus arteriosus and rnild mitral regurgitation. Among 10 cases of karyotyping analysis three cases were diagnosed as trisomy 18. Fourteen fetuses(77.8%) showed growth restriction at delivery. Antenatal obstetric complications were hydramnios(n = 3), oligohydramnios(n =2), and severe preeclampsia(n = 3). CONCLUSION: Careful ultrasonographic evaluation for the identification of a SUA is necessary because of its frequent association with congenital anomaly, growth restriction and cytogenetic abnormality.

One case of malignant acanthosis nigricans associated with internal malignancy has been presented and the suhject of malignant acanthosis nigricans has been revieived. The patient who was 50 year old man had been affected generalized hyperpigmentation with pnpillomatosis especially on forehead, neck, axilla, umbilical area, anogenital area, palm and soles and associated with highly malignant adenocarcinoma of stomach. Diagnosis was confirmed by characteristic clinical appearance, explorative laparatomy and histopathologically
