Trichophyton tonsurans is a major causative agent of tinea capitis in the United States, Canada, Mezico and other Latin American countries, but the infection of T.tonsurans has not been reported in Korea. We report a case of tinea capitis caused by T. tonsurans in a 15-year-old student wrestler. He had a 3*3cm sized non-inflammatory alopecia with black dots on the right occipital area of the scalp. The diagnosis was established by a hght microscopic examination of the affected hairs and by mycological studies from cultures. To our knowledge, this is the first case in which T. tonsurans has been isolated in Korea, It is likely that the student acquired the infection through contact with a foreign wrestler during interaational games and practice. We should be concerned about the potential of spread of this infection in our country.

We report two cases of ectopic epididymal ducts and efferent ductules in the testicular appendices (TAs) of adult men with normally descended testes. In both cases, a sessile TA was incidentally found at the upper pole of the right testis during the scrotal hydrocelectomy. Microscopically, a few closely arranged tubules were detected within the TA. In the first case, the tubules were lined with a pseudostratified columnar epithelium with numerous, long microvilli, and were surrounded by a smooth muscle coat. In contrast, in the second case, the tubules had a wavy luminal surface, because ciliated columnar cells alternated with groups of cuboidal cells. In both cases, strong CD10 immunoreactivity was observed in the luminal border of the lining epithelium. Surgical pathologists should be aware of the presence of both ectopic epididymal ducts and efferent ductules that can occur in TAs, in order to avoid misinterpretation as transected, functional reproductive structures.

PURPOSE: In determining image quality of mammography,many factors are related. Selection of film and screen is one of them. Authors took phantom images of nine film-screen combinations under properly controlled conditions and compared them to evaluate their image qualities. In addition, KVp, mAs and surface dose were evaluated at each combination to deterrhine proper exposure conditions. MATERIALS AND METHODS: Using phantom,images of nine film-screen combinations composed of Fuji MI-NC, UM-MA, UM-MH films and Fuji Fine,Medium, Kodak Min-R screeens were taken. Phantom(Ackermann Mammochip Phantom) was composed of simulations for microcalcifications, fibers, nodules, lymph nodes, breast tissue and breast cancer masses. For phantom of 4.5 cm compressed breast equivalent, 28 KVp was used. For 1.5 and 3.0 cm equivalant phantoms, 24 KVp and 26 KVp was used. At each KVp, mammographic images were taken at various mAs. Among images taken by this process, best images were selected and then, according to scoring method, comparison of image quality for each combination was done. With dosimation strip, surface doses for various conditions were evaluated. RESULTS: Combination of Fuji UM-MA film and Fuji Fine screen showed best image quality regardless of KVp or phantom thickness. For the best image, 10 mAs with 26 KVp was most ideal while mAs with 24 KVp was optimal for equivalent phantom of 3.0 cm thickness breast. At this condition, surface dose was less than other combinations when combinations involving UM-MH films were used. On the other hand,when combinations involving MI-NC films were used, surface dose was higher than others. CONCLUSION: Using phantom, image quality of film-screen combinations could be evaluated and compared. Such process can contribute to best quality image with decreased exposure and can play a role in quality asurance program.
