ABSTRACT
Keloids are benign cutaneous lesions that result from excessive collagen synthesis and deposition. Earlobe keloids are commonly seen as a complication of earlobe piercing and infection. Many different treatment modalities are available; however, therapeutic results are often unsatisfactory. Cryosurgery either used as monotherapy or in combination has been used successfully. However, keloids may require multiple sessions to achieve significant improvement and have a high rate of recurrence. Compared to conventional cryosurgery, intralesional cryosurgery has advantages of proper freezing of the deep layer of the lesion and a less harmful effect on the superficial layers. Herein, we present three cases of earlobe keloid effectively treated with intralesional cryosurgery.

Oriental medicine is a broad range of medical practices that are based on traditions. These traditions include various forms of herbal medicine, acupuncture, massage, exercise, and dietary therapy. The views of the body place little emphasis on anatomical structures, but are mainly concerned with the identification of functional entities. Recently, most oriental doctors have expanded their range of medical treatment into a variety of aspects, and have introduced treatment remedies that include unproved methods, especially into the field of dermatology. Herein, we present 3 cases of adverse effects following the acupuncture for congenital melanocytic nevus, syringoma, and acne scar in oriental medical clinic. With the increasing popularity of acupuncture, we need to understand the current status of dermatologic treatments conducted in oriental clinics.

Onychomycosis is a relatively common fungal infection. Treatment modalities include oral and topical antifungals, surgical treatment or a combination of these therapies. But treatment failure is common and oral drugs may cause toxicity and potential drug interactions. Currently, there are few publications about the treatment of onychomycosis using photodynamic therapy or laser therapy. We report two cases of toenail onychomycosis treated by 1,064 nm Nd:YAG laser.

Eruptive pseudoandiomatosis (EPA) is a rare, self-limiting exanthem, which is characterized by numerous erythematous angioma-like papules surrounded by a pale halo. We report two cases of EPA, which developed in adulthood. The first patient, a 50-year-old female, had erythematous angioma-like papules surrounded by a pale halo on the face and arms. The second patient, a 34-year-old female, had lesions on the upper and lower extremities. The histological features included dilated blood vessels with plump endothelial cells, but there was no evidence of frank vascular proliferation or vasculitis.

Gingival smile is a condition that causes a cosmetic problem by revealing excessive upper gingivae when one smiles. We, herein, report a case of a successfully treated gingival smile by injection of botulinum toxin A to levator labii superioris alaque nasi muscle.

Verruciform xanthoma is a rare benign lesion characterized by verrucous epidermal hyperplasia with aggregates of foam cells in dermal papillae. The pathogenesis is still unknown. Although most verruciform xanthoma tend to occur as isolated lesions, several have been associated with other conditions including squamous cell carcinoma and epidermal atypia. We describe a case of verruciform xanthoma associated with epidermal atypia.

A 61-year-old male was presented with oozing crusted erythematous skin lesions on the ex-tensor site of the right forearm, the extensor site of the left forearm, left calf, right shin, and the right portion of the buttock. He was diagnosed as having multiple pagetoid Bowen's disease by H&E staining, special staining and by an electron microscopic examination. He was treated with a topical application of 5-flurouracil cream and cryosurgery. The skin lesions were mostly healed after 7 months. We herein report a case of multiple pagetoid Bowen's disease on the sun-protected area that may be caused by arsenic ingestion.

Microvenular hemangioma (MH) is a recently described, uncommon, acquired vascular, tumor presenting clinically as a small reddish nodule in young and middle, aged individuals of either gender. Histologically, thin and irregularly branching small venules with inconspicouous lumia and without cellular atypia are found widely throughout the dermis. The presence of histologic features of the collagen dissection and vascular tufts makes it necessary to differentiate MH with Kaposi's sarcoma and angioblastoma. As we are aware, the description of these two cases which showed the characteristic clinical and histologic features of MH, is the first report of MH in Korea.

The association of vitiligo and pernicious anemia has been previously documented. The low levels of folic acid and vitamin B12 were thought to be related to vitiligo. To date, there have been very few reports about the serum levels of folic acid and vitamin B12 in patients with vitiligo. Using radioimmunoassay, we measured the serum levels of folic acid and vitamin B12 in 100 Korean patients with vitiligo. The mean serum levels of folic acid and vitamin B12 were 6.31 +/- 2.82 ng/ml and 630.25 +/- 230.94 pg/ml, respectively, in patients with vitiligo. These levels showed no significant difference compared to the normal control group, suggesting that folic acid and vitamin B12 do not appear to play a role in the pathogenesis of vitiligo.

Sebaceous hyperplasia is not a rare disorder and commonly develops on the face over the age of forty. The typical clinical manifestations are 2 ~ 3mm sized, single or multiple, soft protuberant yellowish nodules with central umbilication and histology shows a group of mature sebaceous lobules and central sebaceous ducts. We report an exceptionally "giant" size of sebaceous gland hyperplasia which lead us to such clinical impressions as an acrochordon, intradermal nevus, and verruca vulgaris. Histologically, the lesion showed a greatly enlarged sebaceous gland composed of numerous lobules grouped around a wide sebaceous duct. Besides the extraordinarily large size of the nodule, the benign proliferating pattern led us to a diagnosis of giant sebaceous hyperplasia.

BACKGROUND: The stratum corneum presents a significant barrier to transdermal drug delivery. Approaches to improve percutaneous absorption of drugs have included iontophoresis and skin penetration enhancers. Oleic acid has been studied as a skin penetration enhancer for drugs, primarily via its action mainly on the stratum corneum lipid structure. OBJECTIVE: The purpose of this study was to assess the interaction between oleic acid and stratum corneum lipids in vivo. METHODS: Male hairless mice were treated topically with oleic acid. Barrier function was assessed by transepidermal water loss measurement and ultrastructural observation with ruthenium tetroxide (RuO₄) staining. RESULTS: Oleic acid in propylene glycol had a profound effect on epidermal barrier function and was found to be concentration dependent. Moreover, ultrastructural examination with RuO4 post-fixation demonstrated that there were marked alterations in the stratum corneum lipid structure. CONCLUSION: This study provides direct evidence that oleic acid increases the epidermal permeability through a mechanism involving the stratum corneum lipid membrane perturbation via the lacunae formation within the stratum corneum.

PURPOSE: In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallgladders. MATERIALS AND METHODS: A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave Iothotriptor. The gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II( 4 rabbits), and group III(3 tabits), respectively. The rabbits were sacrified 6--12 hours later. RESULTS: The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologeic changes with dilatation and structural alterations of endoplasmic reticulums were more profund at value of 100. CONCLUSION: Early histologic changes induced by shock waves are dose dependent and the findings of cellular damage caused by ESWL might be explained as above.
