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.

Annals of Dermatology 1995;7(1):51-53
BACKGROUND: PUVA therapy has been used to treat psoriasis, vitiligo, and various cutaneous diseases. Psoralens are metabolized in the liver and thus can produce liver damage. OBJECTIVE: This study was done to observe the effect of 5-methoxypsoralen on liver function during photochemotherapy. METHODS: Serum transaminase levels were determined before and during photochemotherapy in eighty patients with vitiligo or psoriasis. RESULTS: Four of the eighty patients who had received 5-MOP-PUVA showed elevation of serum transaminase levels. CONCLUSION: Although there have been few cases showing transient elevated values of serum transaminase during 5-MOP-PUVA, it is advisable to obtain liver function tests before and serially during photochemotherapy.

Idiopathic progressive atrophoderma of Pasini and Pierini(IPAPP) is charcterized by sharply dermatcated, atrophic and slate-gray to brownish patches. We report a 17-year-old female with well-defined, atrophic, and brown colored patched on the abdomen, flank, and back. Histologic finding showed marked thining of dermis with thichening of collagen fibers and fragmentation of elastic fibers.

BACKGROUND: Condylomata acuminata is a sexually transmitted cisease which is caused by the human papillomavirus(HPV). The types of HPV causing condylomata acuminata are HPV 6,11,16,18. HPV 16 and 18 are related to anogenital carcinoma. OBJECTIVE: The goals of this study were to determine the types cif HPV in condylomata acuminata, and to investigate the relationship between condylomata acuminata and anogenital carcinoma. MEHTODS: Polymerase chain reaction and restriction fragment le igth polymorphisms were performed in the paraffin-embedded tissues of 17 cases of condylomata acciminata. RESULTS: HPV DNA was detected in all of 17 cases of condylomata accuminata tested. HPV 6 and 11 were found in 53% (9/17) and 41% (7/17) of the samples, respectiiely. HPV 16 and/or 18, which are related to anogenital carcinovia, were not detected, except in one case in which HPV 16 was found to be superimposed with HPV 6 and 11. CONCLUSION: These results suggest that most of condylomata acumirata are caused by HPV 16 and 11, and there is not so much risk of this disease transforming into the aiogenital carcinoma.

Condyloma acuminatum is a common viral disease which is transmitted by sexual intercourse. We experienced a case of condyloma acuminatum occurring in a patient of systemic lupus erythematosus who has been treated with various immunosuppressive agents for 10 years. This condylorna acuminatum was unusual in that it was very rapidly growing, recurrent and reluctant to various treatrnents. We investigated the type of human papillomavirus by Southern blot hybridization and schieved partial improvement by bleomycin intralesional injection together with 5-FU topical application.

To investigate the nature of artifacts caused by air and chemical shift by fat, a test tube phantom study was performed in 2.0T and 0.5T superconducting magnetic resonance imaging systems in various imaging sequences. Spatial mismapping and signal change made image distortion in spin echo images of the air-column and severe signal voids in gradient echo images. Chemical shift artifacts appeared in the planes of frequency-encoding axis as crescent-shaped signal voids and summated bright signals, Both artifacts were more prominent in high field strength, Images at 0.5T showed more severe artifacts in the T2-weighted images than those in the other sequences. As the acquisition matrix increased, truncation artifacts decreased and susceptibility artifacts in gradient echo images diminished. Familiarity with causes, appearances and mechanisms of various artifacts will help radiologists for interpretation of MRI.

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.
