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.

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.

Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

A 62-year-old man presented with a tender, solitary nodule on the left upper arm. He had no specific family history of the lesion. A biopsy specimen showed various sized irregular vascular lumens in the upper dermis. The vascular walls consisted of an endothelial cell layer and rim of one to three layers of glomus cell nests outside the endothelial cells. The cell nests consisted of round shaped epitheloid cells with relatively uniform round or oval shaped nuclei and pale cytoplasm. These tumor cells were strongly positive for vimentin, and a-smooth muscle actin. On electron microscopic examination, the cytoplasm of these tumor cells contained fine filamentous components and many electron dense bodies were found at the plasma membrane and the cytoplasm. We report a case of a solitary glomus tumor(glomangioma) that showed the histological features of the multiple type of glomus tumor. In addition we describe the results of an immunohistochemical and electron microscopic study.

BACKGROUND: Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed erbium:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed erbium:YAG laser skin resurfacing at the setting of low or high energy for pitted acne scars. METHODS: 65 patients with pitted acne scars were included in this study. All patients had skin types III or IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 mJ/pulse, 3.5-5 W in 45 patients and 1,000 mJ/pulse, 7-10 W in 20 patients was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2 week intervals postoperatively. The results of treatment were evaluated for the changes of skin texture and color at 1 month, 3 months, and 6 months. RESULTS: In 45 cases treated with 500 mJ/pulse energy, pitted acne scars were improved about 46.7 % on average and no erythema and postinflammatory hyperpigmentation was observed after 6 months. In 20 cases treated with 1,000 mJ/pulse energy, pitted acne scars were improved about 64% on average and erythema in two patients and postinflammatory hyperpigmentation in one patient were observed after 6 months. CONCLUSION: The results of laser treatment for pitted facial acne scars at the setting of high energy are better than those of laser treatment at the setting of low energy.
