Granular cell tumors are uncommon benign tumors occurring most commonly on the tongue, skin and subcutaneous tissue. They are most often seen as a solitary nodule in adults. Multiple lesions are very rare, particularly in children. We report a case of multiple granular cell tumors in a 13-year-old boy on his left arm which was presented as firm, flesh-colored, match-head to pea-sized, tender nodules for 6 months. Histologically, the tumors are nonencapsulated nodules, composed of large, polyhedral cells with an abundant eosinophilic granular cytoplasm. By immunohistochemistry, the granular cells are strongly positive for S-100 protein.

Nevus lipomatosus superficialis presented as soft, yellowish papules or cerebriform plaques occurring usually on the buttock or thigh, less often on the ear or scalp. We herein report a case of nevus lipomatosus superficialis on the leg.

Basal cell carcinoma is a malignant tumor of the skin that is believed to arise from the hair follicle. In addition to the typical lesion just described, several clinical and histological varieties are recognized. Polypoid basal cell carcinoma, a new distinctive form, has been described as verrucoid, fungating or polypoid mass with stalk and histologically distinguished by restriction of the tumor aggregation to the mass from the other variants. We report a case of basal cell carcinoma of right knee that was pedunculated and had stalk with lobulated surface.

Meralgia paresthetica is a syndrome consisting of numbness, pain, tingling, burning and/or a variety of other paresthesias on the distribution of the lateral femoral cutaneous nerve (LFCN) of the thigh. We report a case of meralgia paresthetica in a 41-year-old woman who complained of the symptoms of pain, burning sensation, and dysesthesia which occurred whilst standing up without any other constitutional symptoms. The authors suspect that frequent. and persistent squatting may play a role in the development of the present symptoms.

We report two cases of proliferating trichilemmal cyst in a 61-ear-old woman and a 44-year-old woman who had a solitary tumor, on the left temporal area of the scalp and right flank, respectively. Histologically, the tumors were localized in the dermis and corisised of multilobulated cysts. The cyst walls were composed of liquamous epithelium showing trichilemmhl keratinization. Some of the cells had clear cytoplasm and were positive on PAS staining. Individiial cell keratinization, mild nuclear atypia were also found in the cyst walls. For the treatment, surgical excision was performed with sufficiert margin.

BACKGROUND: In recent years alternative medicine such as herbal medicines has been attractive and useful in dermatologic therapy. But there is little scientific information about its therapeutic effects and potential side effects. OBJECTIVE: We performed this study to assess the whitening effect of the root of Ma Huang. METHODS: Thirty subjects were tanned by UVB irradiation on their abdomen and 4 pigmented patches in square were obtained. In a single-blind fashion, participants applied the root extract of Ma Huang to two pigmented patches and vehicle to another patch on the abdomen twice a day, and applied nothing to the other patch for 8 weeks. Participants were followed up every week and checked on a melanin index with a mexameter. We also checked the last clinical improvement 8 weeks after the application of the root extract of Ma Huang. RESULTS: MED of the middle back was 73+/-24.66cmJ/cm2. Melanin index of the abdomen was 473.2+/-16.27. Eight weeks after application, the mean change percent of the melanin index of the right upper and lower squares applied with the root extract of Ma Huang were +0.02%(p=0.96) and -0.16%(p=0.76). The mean change percent of the left upper square applied with vehicle was -0.08%(p=0.89). The mean change percent of the left lower square untreated was +0.20(p=0.65). One-way layout ANOVA showed no difference among four squares. Clinical evaluation of improvement did not satisfy: no change 36%; slight improvement 53%; moderate improvement 9%; marked improvement 2%. CONCLUSIONS: The root of Ma Huang did not show the whitening effect on the UVB-induced pigmentation checked by the mexameter but showed slight improvement in visual assessment.
