We report a case of morphea profunda in a 21-year-old male who had diffuse brown sclerotic plaques on his extremities. Laboratory findings showed peripheral eosinophilia and an increased titers for anti-DNA and anti-nuclear antibodies. Histopathologic findings showed diffuse fibrosis and a thickening of the lower dermis and subcutaneous tissue. He has been treated with hydroxychloroquine 400mg per day and the sclerosis of the skin improved.

We present an autopsy case of signet ring cell carcinoma of urinary bladder which underwent widespread metastsis through nearly entire organ. The patient, 45-year old male, suffered from hematuria, dysuria and flank pain for 6 months. Under the diagnosis of the signet ring cell carcinoma by the cystoscopic biopsy, radical cystectomy and ileocutaneous ureteral division were performed. But he died after 11-months after the diagnosis. The autopsy confirmed the widespread metastasis at the lung, kidney, adrenal gland, parathyroid gland, heart, stomach, ileum, spine, rib and meninges. The preveously resected urinary bladder discolosed the well defined fungating mass at the dome and anterio-lateral portion without apparent evidence of the remnant of the urachus. Histologically, the signet ring cells were predominent and focally mucinous pool floating the signet ring cells was noted. We could find several foci of the well differentiated adenocarcinoma and poorly differentiated adenocarcinomas. The above findings may reflect that the origin of carcinoma may be from the multipotential transitional cell epithelium.

This study was carried out to investigate the ultrastructural changes of lens fiber cells, length of gap junctions, and distribution of proteoplycans in cataractous lens. The cataract was induced by stabbing the posterior surface of the lens with 25 gauge needle. The lens were obseved by electron microscopy with estimation of the gap junction. Alcian blue stain was performed for examination of proteoglyscas. The results were as follows. Characteristic changes of the cataractous lens fiber cells were swelling and condensation of the cytoplasm, alterations of cytoplasmic granules including changes of density and size of cytoplasmic granules, and formation of microfibrills, high electron-dense amorphous substance, electron-dense particles, variably sized globular bodies, and multilamellar bodies. The lengths of gap junctions were 2.51+/-1.09um in control and 1.06+/-0.33um in cataractous lens fiber cells(P<0.001). Proteoglycans showing high electron-dense amophorous substance were distributed in the intercellular spaces along the cytoplasmic membrane in control group, but disapperaed in cataractous lens fiber cells. According to these results, it is conceivalble that the changes of the gap junctions and proteoglycans were closely related to the pathogenesis of cataract.

Minimal Change Disease (MCD) is the most common primary nephrotic syndrome in children. Some suggested that tumor necrosis factor-alpha (TNF-alpha) are involved in the pathogenesis of MCD. This study was done to see changes of plasma and urinary TNF-alpha, and its effect on determination of permeability of glomerular basement membrane (BM) contributed by heparan sulfate proteoglycan (HSPG). Study patients consisted of 19 biopsy-proven MCD children aged 2-15 years old. Both plasma and urinary TNF-alpha were measured. Employing the Millicell system, TNF-alpha was screened for the permeability factors. We examined whether TNF-alpha regulated BM HSPG gene expression and HS synthesis in the glomerular epithelial cells (GECs). Urinary TNF-alpha during relapse was also significantly increased (364.4+/-51.2 vs 155.3+/-20.8, 36.0+/-4.5 ng/mg.cr) (p<0.05). However, the negative results were obtained in the permeability assay using the Millicell system. No difference was seen in BM HSPG gene expression and HS synthesis in the GECs. Therefore, it seems that TNF-alpha may not play a disease-specific role in the pathogenesis of MCD.

A 63 year-old man was admatted to our hospital because of dulI epigastralgia. Upper G-I series reveaied the generalized thickened, tortuous mucosal folds in the stomach and duodenal bulb, Two ovold large pits on the antrum were observed endoscopically, Tha relevant literatures on the subject were reviewed.

Lichen planus is a common, usually intensely pruritic papulosquamous dermatosis with unknown etiology, which may involve the skin, mucous membranes, hair follicles, and nails. Its lesions are usually a localized form but generalized ones are an unusual presentation of lichen planus. We report herein three cases of generalized lichen planus in one male and two female patients, which was diagnosed on clinical and histopathological examinations in all cases.

General endotracheal anesthesia with mechanical ventilator is a common anesthetic practice since introduction of various anesthetic ventilator. A mechanical not only deoreases workload but also allows the anesthesiolosist to better nonitor and manage the patient during the operation. However, acoidental complications can be encountered during the wse of ventilator as with all other modern equipments. Several authors have described that increased pulmonary pleasure from poaitive pressure ventilation mar lead to alveolar rupture with subsequent dissection of air along the vascu- lar structure of the lung into the hilum and then into the tissue plane of the mediastinum. We report a case of pneumomediastinum, pneumoperitoneum and subcutaneous emphysema without pneumothorax which occured during discoidectomy under the endotracheal ventilator anesthesia.

A 12-year-old boy developed cholestatic hepatitis with Steven-Johnson syndrome following the use of amoxicillin. The skin lesion and general condition were improved over 2 weeks, but jaundice was gradually aggrevated. We performed liver biopsy, on 30th hospital day, which showed cholestatic hepatitis. The patient improved gradually and liver function was normalized 5 months later.
