Tinea pedis is frequently found in people with poor personal hygiene and in hot, humid environments. The authors investigated the clinical, epidemiological, and mycological characteristics of tinea pedis in 170 garbage workers(166 males and 4 females) employed in a garbage plant in Seoul, Korea. 40 were clerical workers and 130 were field workers. Tinea pedis was found in 134 with a prevalence rate of 78.8%. Of those 134, 61(45.5%) also had onychomycosis. The prevalence of tinea pedis increased with age and the period working in garbage plant. However, there was no difference in the prevalence of tinea pedis between clerical workers and field workers, mitigating against the conclusion that their tinea pedis may be of occupational origin. Clinically tinea pedis was classified into 4 types ; interdigital (41.8%), vesicular(23.1%), dry squamous(22.4%), and mixed(12.7%). KOH smear positivity and culture positivity was related to clinical types of the lesion the lowest in the interdigital type. In the interdigital type, the etiology of nonmycotic lesions could not be identified. Negative fungal cultures could have been due to secondary bacterial infections. 63 strains of dermatophytes were isolated; 54 strains of Trichophyton rubrem(85.7%), 8 strains of Trichophyton mentagrophytes(12.7%) and 1 mixed infection of T. rubrum and T. mentagrophytes. T. mentagrophytes was isolated only from the vesicular lesions. 8 strains of yeast forms, positive in KOH smears and yielding pure colonies, were also isolated, and repeated mycologic examination yielded the same results. Among them, at least 4 cases of Trichosporon beigelii, and 1 case of Candida parapsilosis were considered to be of pathogenic significance.

Cutaneous leiomyoma is a benign tnmor originating from smooth muscle fibers which are derived from arrector pili muscle, media of blood vessels and dartoic muscle of scrotum, vulvar, or nipple. It is classified into 3 types according to the site of origin, namely pilar leiomyoma, angioleiomyoma and genital leiomyoma. Leiomyoma of the nipple is the less kquent type of cutaneous leiomyoma. We report a case of cutaneous leiomyoma on the nipple in a 53-year-old man.

This study was undertaken to investigate the efficacy of 5% PABA cream using mouse ear swelling reaction(ESR). Mice were exposed to 100mJ/cm of UVB, five times a week for four weeks, on the both ventral aspect of the ear, with application of 5% PABA cream on the right ear. The results were as follows : 1. The intensity of ear swelling reaction of 5% PABA protected group was reduced greater than unproteeted group after the first 3 days of UUR. 2. The intensity of ear swelling reached at peak after 1 week of the ultraviolet radiation. Thereafter it has decreased gradually the following 4 weeks. The difference of ear swelling between the two groups was the greatest after 1 week, and the sunscreening efficacy of 5% PABA cream has remained persisted for 4 weeks. 3. The number of mice which have shown severe inflarnmatory response after ultravioiet radiation was more in unprotected group than that in 5% PABA protected group. 4. Determination of mouse ESR is considered a good method for the evaluation of longterm efficacy of sunscreen preparation.

BACKGROUND: Erythema induratum was first described by Bazin in association with tuberculosis. However, the tuberculous cause of this entity has been questioned by several authors and gradually, the concept of nontiiberculous nodular vasculitis has been accepted OBJECTIVE: The purpose of this study is to document the clinicopathologic features of erythema induratum. METHODS: We investigated clinical and histopathological findings of 31 patient with erythema induratum who showed positive tuberculin hypersensitivity reaction or had active associated tuberculosis. RESULTS: The ages of the 31 patients(M7: F24) ranged from 13 to 66 years(mean 37.1 years). All patients displayed recurrent crops of tender, painful, violaceous noudules or plaques. Most lesions were present on the legs, but they also occurred on the thighs, feet, buttocks, and forearms. The skin lesions evolved for several weeks and healed with scarring and residual pigmentation. Histological examination revealed lobular or septolobular panniculitis with varying cornbinations of granulomatous inflammaticn, primary vasculitis and necrosis in most biopsies. Twenty two patients were treated with isoniazid alone and the remaining 9 patients received combination anti tuberculous treatment. Relapses were encountered in 4 patients who received isoniazid alone or stopped the medicationrgainst medical advice. CONCLUSION: A diagncisis of erythema induratum should be rendered in the presence of relevant clinicopathologic features, strong positive Mantoux test reaction, and good therapeutic response to antituberculous treatme,it. A full course of combination antituberculous therapy is indicated to achieve a cure of the skin lesions of erythema induratum.
