Recurrent infantile digital fibroma is a peculiar fibrous tumiir that may be single or multiple on fingers and toes of infants and children. We report a 5-year-old gril with recurrent infantile digital fiber oma which was recurrent on the left 5th toe. The lesion had noted at the age of 6 months. and was excised surgically when the child was 3 year old. 2 years after operation, the lesion was recurred in operation site. Microscopically, nodular fibrous mass is attached to flattened,pidermis. The underlying nodule is composed of proliferating fibroblasts surrounded by derse collagenous tissue. We could find eosinophilic inclusion bodies in the cytoplasm of fibro ilast. It was stained pink with H&E, bright red with Massons trichrome and purple with PTAH.

We report herein a case of impetigo hepetiformis treated with etretinate. The patient was 30 year old female in the 7th month of her second pregnancy, who had suffered from generalized coalesced pustular eruption with slightly itching and hurning sensation with fever on whole body except face, both had and foot. The euption began as an erythemations patch which developed pustules along the mar gin. I'here was extensian by the develupment of fresh peripheral pustules and coaleence of these patches. Histopathological findings showed hyperkeratosis, subcorneal spongiform pustule, spon,iosis in the epidermis and vascular proliferation in the devmis, She was treated successfully with etretinate for 4 weeks.

We report a patient who had been initially diagnosed as a myelodysplastic syndrome in 1998 presenting purpuric patches on the left arm that started to develop about a year prior. The purpuric lesions were diagnosed as leukemia cutis by skin biopsy. Her subsequent bone marrow biopsy showed progression into an atypical chronic myeloid leukemia with increased numbers of leukocytes in the peripheral blood. Leukemia cutis typically is regarded as a sign of progression of disease or a manifestation of recurrent disease in treated patients with an established diagnosis of leukemia. We suggest that the skin lesion in this patient could have been a sign of con-version into atypical chronic myeloid leukemia.

The bacteria as well as the fungi can build up resistance against different kinds of drugs or can decrease in sensitivity to these drugs. Therefore it is necessary that we use the MIC test for acertain period of time to determine the right concentration of drug to use in therapy. The culturing of P. orbiculare was successful in 1951. Up until that time, there were few drugs available to use in the MIC test. So, treatment for Tinea versicolor was dependent upon ones previous experience in determining the drug's effective concentration. Therefore, we performed the MIC test of clotrimazole, sodium thiosulfate, selenium sulfide, propylene glycol against P. orbiculare. The diagnos is for Tinea versicolor in the patient was confirmed by using KOH smear and by the clinical manifeststion. The fungi were then isolated in a culture from an olive oil rich media Mixture of isolated fungus and olive oil was applied to the lateral side of a healthy male's right upper extremity. After one week, P. orbiculare was confirmed by wood lamp examination, KOH smear and culture. After confirmation of P. orbiculare, a variety of concentrated drugs were used. Then media, containing propylene glycol, sodium thiosulfate, selenium sulfide and clotrimazole with a small amount of olive oil was used in inoculations of 10 viable unit/ml of P.orbiculare in attempt to estblish the MIC test. Test results are as follows: l) Propylene glycol MIC Range; 12. 5mg/ml~7. 5mg/ml. 2) Sodium thiosulfate MIC Range; 500mg/ml~7. 5mg/ml. 3) Selenium sulfide MIC Range; l. 25mg/ml~0. 04mg/ml. 4) Clotrimazole MIC Range; 0. 5mg/ml~ 0. 0005mg/ml.

BACKGROUND: Laser resurfacing of cutaneous scars, rhytides, and photodamaged skin has become very popular. Pulsed erbium:YAG laser resurfacing has recently come into favor for the treatment of pitted acne scars. OBJECTIVE: This study was designed to investigate the efficacy and safety of pulsed erbium:YAG laser in cutaneous resurfacing of pitted acne scars. METHODS: 100 patients with pitted acne scars were enrolled in this study. All patients were treated by means of a pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 to 1000mJ/pulse and fluences used varied between 5-15J/cm2. Photographs of the face were obtained at baseline and 2 week postoperatively. Two weeks after treatment, postoperative care such as applying hydroquinone 4% and tretinoin 0.05% was recommended for 2 to 4 weeks. RESULTS: Out of 100 patients, 20% of patients showed an excellent response, 50% a good response, 21% a fair response and 9% a poor response. After 6 months, erythema had developed in two patients and and three patients had developed postinflammatory hyperpigmentation, hypopigmentation and delayed contact dermatitis. CONCLUSION: Treatment with pulsed erbium:YAG laser shows high efficacy and low morbidity in pitted acne scar resurfacing.

Trichost.asis Spinulosa consists of several fasciles of reta ned vellus hairs in the hyperkeratotic sebaceous follicles, resulting in a dark slightly raied horny follicular spines, resembling comedones on the trunk and face. The condition is relatively common, particulary among the age, but is usually overlooked on routine skin examination as the patient is rarely aware of it.. We report 6 cases of trichostasis spinulosa, which showed numerous asymptomatic tiny black comedo-like dots on their backs. We obtained the follicular material by tweezer, which consised of several vellus hairs surrounded by a keratinous plug. Histologic examination was done in 3 patients, one of whom showed a rarely reproted double follicle and double papilla. With scanning electron microscopy, we observed multiple vellu hairs embedded in a keratotic plug, emerging from a hair follicle opening.
