PURPOSE: We investigated the possible inhibitory effect of aspirin during the initiation and post initiating stages on N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) induced bladder carcinogenesis in female rats. MATERIALS AND METHODS: Forty-five female Sprague-Dawley rats were divided into three groups. Group A received 0.05% BBN in drinking water for 12 weeks. Group B re ceived 0.05% BBN in drinking water with 0.5% aspirin in the diet for 12 weeks. Group C received control diet without added chemicals. The rats were sacrificed after 12 weeks. For identification of chemopreventive effect of aspirin, apoptosis was detected by in situ cell death detection method. The apoptotic index (AI) was calculated from the ratio of typical apoptotic cells relative to the total cells from observation of at least 1000 cells in each preneoplastic lesion among the groups. RESULTS: All cases of group A showed multiple lesions of simple and focal hyperplasia. The incidence of papilloma was 80% in group A. All cases of group B also showed multiple lesions of simple and focal hyperplasia but the incidence of papilloma was decreased to 20%. The total numbers counted of focal hyperplasia and papilloma lesions were significantly reduced in group B than in group A (p<0.001 and p<0.001, respectively). The mean AI in group A and B sequentially increased in preneoplastic lesions, as compared to that in the normal epithelium of the rat bladder. Significant differences in AI in the lesions of simple and focal hyperplasia between group A and B were noted (p<0.001 and p<0.001, respectively). CONCLUSIONS: The result suggests that aspirin significantly decreases the incidence of precancerous lesions and it can act as a chemopreventive agent for precancerous lesions of urinary bladder.

Eczema herpeticum is a herpes simplex virus infection with disseminated skin involvement superimposed on a pre-existing dermatosis. Dariers disease has been reported to be among the dermatoses susceptible to the sudden onset of a widespread vesicular eruption accompanied by high fever known as Kaposis varicelliform eruption. We report a case of eczema herpeticum in a 46-year-old woman associated with Dariers disease.

A 51-year-old Korean woman presented with a non-tender, well-demarcated, reddish, edematous patch on the right anterior chest where a previous mastectomy and radiation therapy had been performed. She had been diagnosed as having infiltrating ductal carcinoma of the right breast about 1 year ago. Histopathological findings of the skin lesions were consistent with inflammatory metastatic carcinoma of the breast. Inflammatory carcinoma or carcinoma erysipeloides is a well-established entity most frequently associated with carcinoma of the breast. It is characterized by dermal lymphatic invasion by malignancy and clinically should be distinguished from erysipelas or cellulitis. We describe a case of inflammatory metastatic carcinoma derived from an infiltrating ductal carcinoma of the breast which can be clinically confused with radiation dermatitis.

Favre-Racouchot syndrome is a disease of senile or actinic processes and another name is nodular elastosis with cysts and comedones. Clinically, facial skin shows, especially lateral to the eyes, multiple open and cystically dilatated comedones and can be defined as cutaneous disturbances characterized by a degenerative process of the dermis associated with cysts and comedones. Sunlight is a strong causative factor and dermal degenerative processes result in this condition. We report the case of a 78-year-old man who showed multiple yellowish papules on both sides of cheeks, the periorbital and, malar areas. He had had this condition for 25-years. His job used to involve physical labor and much exposure to sunlight. An excisional biopsy specimen from the facial malar lesion showed cystically dilated comedones with basophilically degenerated dermal tissue. We performed a therapeutic excision on the two large nodular lesions on both malar areas and applied topical tretinoin. The Patients clinical appearance was much improved 2 months later.
