Hyperkeratosis of the renal pelvis and ureter is a rare condition and is explained by the metaplastic change from transitional to cornified squamous epithelium. This lesion is frequently associated with, and perhaps caused by chronic urinary infection, but potentially premalignant, accompaning with carcinoma in about 10 to 20 per cent of the cases at the time of diagnosis. A case of hyperkeratosis of renal pelvis & ureter which was clinically suspected of carcinoma in a 49-year old woman with a long history of chronic pyelonephritis is presented with review of literature.

BACKGROUND: Chronic exposure to ultraviolet radiation(UVE) nduces photoaging characterized by dry, deeply wrinkled, inelastic, leathery, and irregulaity pigmented skin. UVR also induces solar keratosis and carcinoma, and is a contributing factor in melanoma. Sunscreens are used to prevent solar damage to skin and, if used on a daily lass should significantly reduce the incidence of the chronie photodamaging events. OBJECTIVE: We tried to evaulate the photoaging effects of UVR in the skin and the photoprotective effect of sunscreens. METHOD: We examined the gross and microscopic changes skin of albino hairless Skh : HR-1 mice exposed chronically to ultraviolet B(UVB) and suncreen-treated mice. RESULTS: The skin of the UVB-irradiated mouse shows chear, cteristic signs of photoaging, such as deep wrinkles across the back, and thickened and a hery skin. Histologically, the photoaged skin shows increased epidermal thickness, numeross fibroblasts and inflammatory cell infiltration in the upper dermis, and many enlarged keratering cysts in the lower dermis. By the 20th week, seven of the total of 9 mice(78%) in UVB irradiated mice developed at least one tumor. Histologically, the tumor is a papilloma, but the he are many dyskeratotic cells and loss of polarity in epidermis. Octyl methoxycinnamate or TiO ZnO Talc-treated mic show a significantly decreased wrinkling score, mimmal epidermal hyperplasia, slightly increased dermal cellularity, and lack of proliferation of cysts. The octyl dimethyl PABA-treatd mice shows significantly increased wrinkling score and marked inflammatory infiltration dermis. By the 20th week, only one mouse had developed a tumor in the octyl methoxy irmamate-treated group and no evidence of tumor was seen in the TiO ZnO Talc-treated group. In the octyl dimethyl PABA-treated group, five of 7 mice(71%) developed at least one tumor. CONCLUSION: The skin which is chronically exposed to UVB is subject to photoaging and photocarcinogenesis and regular use of an adequate sunscreen would prevent these photodamaging effects of UVB.

Chronic sclerosing sialadenitis, Mikulicz disease or Kuttner tumor has been recently recognized as a spectrum of IgG4-related sclerosing disease. IgG4-related disease is characterized by a high serum IgG4 level and tissue infiltration of IgG4-positive plasmacytes. We report three cases of chronic sclerosing sialadenitis with variably associated systemic involvement. All patients presented with a submandibular mass or swelling, and all the resected submandibular glands showed diffuse lymphocytic infiltration, lymphoid follicles, and septal fibrosis. Two of the specimens revealed numerous IgG-positive plasma cells, most of which were IgG4-positive on immunohistochemical staining. One of them was associated with dacryoadenitis and hypophysitis. The other patient had ureterorenal lesions. Immunohistochemical study was unavailable in remaining one case, but the histologic features along with elevated IgG level and associated pancreatitis supported the diagnosis. All patients received steroid therapy postoperatively and are doing well. Salivary gland involvement in IgG4-related fibrosclerosis should be recognized in systemic medical pathology.

Sudoriparous angioma is an unusual form of angioma with pain and hyperhidrosis. We present two cases of typical sudoriparous angioma. Case 1: 9-year-old female showed 0. 8 to 2. 0cm multiple dark brownish tender palpable hypertrichotic masses on the right lower leg after birth. Muscular atrophy and flexion contracture was also developed on the right lower leg for 2 years. Case 2: 4-year-old rnale showed 3 * 3cm tender elevated mass on the left shin after birth. Marked hyperhidrosis was developed when even slight pressure applied on the lesion in these cases. On histologic examination, these two cases showed proliferation of varible sized blood veasels hyperplasia and dilated hyperplastic eccrine glandular and ectopic adipose tissue on the mid and deep dermis. Muscular biopsy from case 1 showed fibrotic and degenerative change. Electromicroscopic examination done from case 1. The secretory epithelial cell of eccrine gland showed cytoplastic degradation and slight dilated intercellular canaliculi (Fig. 11). The lumen of subepithelial capillaries were dilated and some of endothelial cells showed degenerative changes evidenced by RER dilation, mitochondrial swelling and detachment from underlying tissue(Fig. l2). The cutaneous nerve showed many non-myelinated axons enclosed in cytoplasm of Schwann cells.

BACKGROUND: The proper management of the patients with hypotention remains a difficult clinical problem. This study was designed to evaluate the efficacy and safety of gepefrin in the treament of symptomatic hypotensive patients in outpatient clinic of university hospital. METHODS: Thirty milligrams of Gepefrin was given twice daily for 4 weeks in 30 patients with hypotension(6 males, 24 females ; 23-60 years of age). Blood pressure, heart rate, subjective symptoms and side effects were checked before medication and at the end of 1st, 2nd, 3rd, 4th week of medication. RESULTS: 1) Grpefrin increased sitting systolic blood pressure significantly(p<0.05) by the end of 1st week and thereafter. 2) Hypotensive symptoms were improved in 76% of hypotensive patients and overall rate of usefulness was 70%. 3) Heart rate did not change significantly. 4) One patient complained of loose bowel movement and another one, of anorexia among 30 study patients and all laboratory parameters were within normal limits before and after drug treatment, thus the rate of safety was 93%. CONCLUSION: Results from this study suggests that gepefrin 60mg daily increases the blood pressure mildly and improves the symptoms moderately in symptomatic hypotensive patients.

Leiomyoma Cutis is an unusual benign tumor of smooth muscle derivecl either from the arrector pili muscle, from the media of blood vesseles, or from smooth muscles of scrotum, labia or nipple. Two casea of leiomyoma cutis confirmed by H&E stain and Massons stain is presented, one with lesion on the left thigh and the ather with lesion of the left ankle. The first case was a 49 year-old female with solitary pinhead sized subcutaneous firm mass with intermittent pain and tenderess for 10 months, The second case waa a 36 year-old female with painful solitary peanut sized firm nodule which had pinkish center of 1 year duration.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.
