Itraconazole is the first orally active triazole antifungal agent. Authors performed multicenter trials to evaluate the therapeutic effect of itraconazole in dermatophytoses. During 6 months from September, 1988 to February, 1989, 246 patients with dermatophytoses were included in this study. 74 of these cases lost to follow-up and 3 cases developed drug eruption were excluded from analysis of therapeutic efficacy. Duration of therapy were 4 weeks in tinea pedis and tinea manus, and 2 weeks in tinea cruris and tinea corporis. The obtained results were as follows : 1. The everall cure rate of itraconazole in dermatophytoses were 81.3%, and the cure rate in each dermatophytosis were 80.3% in tinea pedis, 100.0% in tines manus, 85.3% in tinea cruris and 68.6% in tinea corporis. 2. The cure rate at two weeks after completion of the therapy(81.3%) was higher than that at the end of the therapy(74.3%). 3. Trichophyton rubrum(70.0%), Trichophyton mentagrophytes(81.3%), Microsporum canis(7.3%) and Epidermophyton floccosum(0.9%) were isolated from 110 cases among the enrolled patients. 4. Seven of the 190 patients experienced adverse effects of the treatment: abdominal discomfort(one); nusea(one); constipation(two); and drug eruption(three). Therefore we impressed that itraconazole is an effective and safe new oral therapeutic: agent for dermatophytoses.

Elephantiasis nostras, the result of recurrent skin infection or chronic lymphedema is characterized by marked skin fibrosis and massive enlargement of a body part. We present a case of elephantiasis nostras due to chronic recurrent erysipelas which affected the lower extremities in a 62-year-old man. The patient had had persisting non-pitting edema, and tender multiple verrucous brownish plaques and nodules on both lower legs for 1 year. On histological examination, there was hyperkeratosis and papilomatosis in the epidermis, fibroplasia, dilated thick walled venules and collagen fibers oriented vertical to the skin surface, and hyperplasia of eccrine ducts in the dermis.

Pedunculated lipofibroma is a rare disorder characterized by ectopic deposits of mature adipose tissue in the dermis. It is a dorne shaped or sessile papule which occurs at any site and develops later in life. We, herein, report two cases of pedunculated lipofibroma which have developed on the chin of a 64-year-old man and the buttock of a 47-year-old woman.

BACKGROUND: c-erbB-1 (epidermal growth factor receptor) and c-erbB-2 oncoprotein have common tyrosine kinase activities, and alteration in their expression has been defined in various visceral tumors. However, relatively little is known about their expression in skin tumors. OBJECTIVE: Our aim was to evaluate the distribution and expression pattern of c-erbB-1 and c-erbB-2 in skin neoplasms. METHODS: We have undertaken an immunohistochemical survey of c-erbB-1 and c-erbB-2 in the tissue specimens of keratoacanthoma (KA), actinic keratosis (AK), squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). RESULTS: Membranous c-erbB-1 expression had a tendency to be down-regulated in some specimens of SCC and dysplastic portions of AK. In invasive lesions of SCC, we observed increased cytoplasmic accumulation of c-erbB-1. Most specimens of BCC showed rather decreased expression of c-erbB-1 compared with other skin tumors. c-erbB-2 oncoprotein showed strong cytoplasmic staining in SCC, especially in the invasive tumor mass, and in some deeply dysplastic or hyperplastic portions of AK, though the difference of intensity was not striking between tumors. BCC revealed relatively weaker expression of c-erbB-2 than other skin tumors, which was similar in pattern to c-erbB-1. CONCLUSION: The expression patterns of c-erbB-1 and c-erbB-2 are altered in various skin neoplasms, and seem to be related to the dysplastic status or differentiation level of tumor cells.

Myeloid body formation is an ultrastructural feature of gentamicin induced nephrotoxicity in human being and experimental animals. The origin of the myeloid body is not satisfactorily understood and morphological verification of the developing process of this structure is not fully accomplished. We injected 100 mg/kg/12 hour of gentamicin in 20 Spraque-Dawley rats and examined the ultrastructural feature of the proximal convoluted tubular cells of the kidney every 30 minutes in the first 4 hours, and in 5 hours, 6 hours, 12 hours, 24 hours and 48 hours after injection of gentamicin, with a TEM and a SEM. Myeloid bodies were noted as concentric layers of membranous structures of degenerated endoplasmic reticulum and mitochondria in the lysosome. The number and size of the myeloid body containing lysosomes were increased with time. We can deduce from this observation that injured cell organelles by diffusible gentamicin within the cells are autophagocytosed by lysosomes which were also injured by the drug from pinocytotic vesicles, and incompletely digested organellar remnants are retained in the lysosomes as myeloid bodies. So we think that the myeloid body formation is a result of an exaggerated and a pathologic autophagocytic process due to cell injury induced by gentamicin.

We report herein a case of lymphomatoid papulosis in a 23-year-old female who had recurrent erythematous pinhead to pea sized papules and nodules on the both inner thighs and forearms for 4 years. Some lesions showed central hemorrhagic necrosis or scale formation. Individual lesions persisted for several months and showed spontaneous regression leaving pigmentation or depigmented atrophic scar. Histopathologically, there was marked cell infiltration, especially in the dermoepiderrnal junction and perivascular area. Infiltraled cells consisted of sorne ncutrophils and numerous atypical cells that had variable sized and irregular shaped nuclei. Electronmicroscopically, some atypical cells had cerebriform nuclei with marked peripheral condensation of chromatin and cytoplasm contained a few organelles, many polyribosomes and some dense bodies.

This study was designed to investigate the effect of local hyperthermia on contact hypersensitivity (CHS) and elucidate it's mechanism through assessment of number of epidermal LCs and transfer of spleen cells. Depilated dorsal skin of mouse was immersed into controlled water bath at 52 ℃ for 30 seconds in vivo. The number of epidermal LCs was counted by adenosine triphosphate staining, and CHS to 2,4-dinitro-l-fluorobenzene was assessed by ear swelling and transfer of spleen cells. The number of LCs was significantly reduced 1 to 3 days after the hyperthermia treatment and recovered to normal 5 days after the treatment. CHS was significantly suppressed in mice sensitized 5,7, or 10 days after hyperthermia treatment, but the suppression was meager in mice sensitized 1 or 3 days after the treatment. There is a discord between the number of LCs and degree of CHS. When mice received spleen cells from hyporesponsive donors, CHS was remarkably sup-pressed in the recipient mice compared with positive control. These findings suggest that tfeatment of local hyperthermia suppress CHS in mice, which may be associated with the induction of suppressor cells. The nature of the discord between the the number of LCs and degree of CHS in this investigation remains to be cleared by further studies.

We report an extremely rare case in which two tuberculids, papulonecrotic tuberculid and erythema nodosum, occurred together. A 16-year-old girl had two types of clinically distinct lesions; asymptomatic necrotic papules on the upper and lower extremities and painful subcutaneous nodules on the legs. A Mantoux test showed a strong positive reaction. Histopathologic findings of the necrotic papule and subcutaneous nodule were consistent with papulonecrotic tuberculid and erythema nodosum, respectively. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for tuberculous bacilli in the papulonecrotic tuberculid lesion revealed a negative result. Antituberculous therapy brought a rapid clinical improvement of both lesions.

Male breast cancer is a rare disease, representing approximately 1% of breast cancer and less than 1.5% of malignant tumors occurring in men. We report a case of cuaneous metastasis of male breast cances. a 64-year-old male who presented with multiple nodules and erythematous plaque on the right anterior chest and enlargement of the right axillary lymplinodes. The histopathologic findings of the nodule showed atypical tumor cells with a somew eat gland-like pattern. The cells showed potive reactions in PAS, DPAS and alcian blue stains, and also positive for estrogen and roiesterone receptors. Biopsy specimens taken from the plaque showed cellular arrangement in show line, referred to as Indian filing, between thiclenecin collagen bundles. He was treated not, tamoxifen, 5-fluorouracil, adriamycin, cyclophosphamide and megestrol acetate. 5 months after nitiation of the treatment, the skin lesions were improved vvith a decreased number and size or dules and decreased intensity of erythema.
