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.

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.

BACKGROUND: The efficiency of lipid extraction by different kinds of solvents from stratum corneum may vary. OBJECTIVE: To assess the efficiency of lipid extraction by several solvents from the stratum corneum, the total lipids weights were measured by an electronic microbalance, and lipids compositions of a stratum corneum were analyzed by thin layer chromatography(TLC) after pretreatment of several solvents, respectively. METHODS: Stratum corneums separated fro circumcised prepuce were pretreated with acetone, petroleum ether, or distillecl water for 10 minutes. Lipids of stratum corneum were extracted with methanol chlorofonn-H,O mixture(4: 2: 1.6, v/v, Bligh Dyer solvent). Lipids weights were weighed, and the ratio of lipid weight and wet weight of stratum corneum were measured. TLC was performed and lipids compositions were quantitated by photodensitometer. Lipids extraction in viva was performed on both forearms. After two times stripping with sellotape, lipids were extrected with the solvents using cup method. These were dried and lipids weights were weighed. RESULTS: The efficiency of lipid extraction from the stratum corneum of circumcised prepuce were acetone, petroleum e1 her, and distilled water in decreasing order. All groups were similar in the compositions of the stratum corneum lipids except for those of cholesterol esters and sphingolipids. The efficiency of lipid extraction from in vivo skin were ranked in order from petroleurn ether, acetone, down to distilled water. The efficiency of lipid extraction of petroleum ether and acetone were higher than that of distilled water. CONCLUSION: The efficiency of lipid extraction is influenced by the kinds of solvents as well as the materials and the methods of extraction.

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.
