To investigate the heterogeneity of fibroblast proliferation rate depending on the depth of dermis in the psoriatic skin lesions, fibroblasts were obtained from the upper and lower dermis of the forearm skin lesions in 9 psoriatir, patients and of the comparable sites in 7 healthy persons respectively, and were cultured. The in vitro proliferation rates of the fibroblasts were calculated by measuring the efficiency af cell attachment, cell numbers on varying days of culture and the population doubling time during the 3rd passage of subculture. The results were as follows: 1, The efficiencies of cell attachment at 24 hours after seeding were not statistically different between the upper derrnal fibroblasts and the lower ones in both psoriatic skin lesions and normal skins. 2. By rneasuring the cell numbers and the population doubling times, the prolifeatior rate of the upper der mal fibroblasts was greater than that of the lower ones in both psoriatic skin lesions and normal skins and that the fibroblastic proliferation rate was significantly inereased in the psoriatic skin lesion compared to the normal skin.

KOH examination is a simple, rapid and diagnostic procedure to confirm dermatophytic infections. It is important to select a proper examination site of the lesion. To determinate the proper examination site of the lesion, mycologic studies were done with multiple specimens collected from the center, margin and out of margin of the ring-shaped dermatophytic skin lesion on the 58 patients. The results were as follows. Positive rate of KOH wet smear was 94.8% at the center and 100% at the margin of the lesions, 22.4% at the 1 cm and 5.2% at the 2 cm out of the lesions. The more hyphae were found in the lesion, the more hyphae were found out of the lesion. Culture was done on the Sabouraud's glucose agar from the highest KOH positive area and the positive culture was 48 strains (82.8%) of 58 patients. These findings suggested that the ring-shaped active margin was the best site to examine mycologic studies.

Weber-Christian disease is a relapsing, febrile, nodular, nonsuppurative inflammation of the subcutaneous fat tissue. Many authors reported these cases which illustrate the great variability of the clinical manifestation, such as acute or chronic, fulminating or transient, febrile or non febrile, systemic or cutaneous. Two of our cases have had recurrent painful subeutaneous nodules without fever for several years. Biopsy showed a nonspecific inflammatory panniculitis with lymphocytes chiefly, and small amount of histiocytes and foamy cells. It should be suggested Weber-Christian disease when subcutaneous nodules appear recurrently same areas of the whole body surface except anterior aspects of tibia even if no fever as systemic manifestation. Treatment with steroid and chloroquine diphosphete produced good improvement.

Metaplastic carcinomas (carcinomas with metaplasia) of the breast are difficult to accurately diagnose and classify because of their rarity and varied histologic patterns. Cystic change can be encountered in mammary carcinoma, especially in carcinoma with squamous metaplasia, but are rare in pseudosarcomatous metaplastic carcinoma. We recently experienced a case of pseduosarcomatous metaplastic carcinoma in a 69-year-old female who had an extensive cystic change in radiologic and histopathologic findings. The precise cell type that gives rise to metaplastic carcinomas remains uncertain. Immunohistochemical findings raised the possibility of the myoepithelial nature of the tumor.

It is generally recognized that several chemical mediators are involved in tbe pathogenesis of sunbum; however, the exact mechanism is still to he resolved. Recently, prostaglandin has been found to be one of the inflammatory mediators in sunbum, particularly in the delayed erythema response and several investigators have shown that the nonsteroidal antiinflammatory drugs inhibit the in vivo synthesis of prostaglandin. On the assumption that the nonsteroidal antiinflammatory drugs might exert a beneficial effect on the sunbum through the antiprostaglandin effect, several authors have reported the effect of indomethacin on sunbum. This study was undertaken to evaluate the effect of topical indomethacin on the delayed erythema response induced by artificial sunlamp and sunlight by clinical and histopathological examination. Indomethacin(2. 5% ointment, 2. 5% solution, 5% solution) was applied immediately after 3 MED irradiation of artificial sunlamp to the shaved back skin of 6 healthy albino guinea pigs weighing 550-850gm and 9 human volunteers and the delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours after irradiation respectively. Punch biopsies of the skin were performed on 6 guinea pigs at 6, 12, 24 a.nd 48 hours after irradiation and the histologic changes were observed. Four human volunters were exposed t,o 3 MED of sunlight and indomethacin preparations were applied immediately after irradiation. The delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours postirradiation and in one volunteer, the skin was biopsied at 24 hour for histologi.c evaluation. The results were as follows: 1. Topical indomethacin in ointment or solution forms delayed and decreased the appearance and degree of erythema induced by sunlight and artificial sunlamp in both human and animal subjects. 2. Histologically, the number of sunbum cells at 24 hour in the epidermis of one human volunteer was decreased on indomethacin applied sites. The dermis showe6 no difference in histologic changes between control and indomethacin sitea. In animal study, however, no detectable difference in epidermal or dermal changes was observed between control and indomethacin applied sites. The autors confirmed that topical indometha,cin was effective in delaying and blanching of the delayed erythema of sunbum in guinea pigs as well as in human volunteers, though there was no difference in histologic changes between indomethacin and control sites in guinea pigs. The mechanism involvel on this aspect is remained to be resolved.
