It seems that the recipient site may have an influence on the transplanted hairs. Further studies are needed, including clinical, histopathologic, and molecular biological methods.

Dermatophytes have the ability to form molecular attachments to keratin and use it as a source of nutrients, colonizing keratinized tissues, including the stratum corneum of the skin. Malassezia species also affect the stratum corneum of the skin. Therefore, dermatophytosis and pityriasis versicolor of the skin are thought to be important factors of profound changes in skin barrier structure and function. We aimed to describe the changes in transepidermal water loss (TEWL), stratum corneum hydration, and skin pH in the lesions of the dermatophytosis and pityriasis versicolor. Thirty-six patients with dermatophytosis (14 with tinea cruris, 13 with tinea corporis and nine with tinea pedis or tinea manus) and 11 patients with pityriasis versicolor were included in this study. TEWL, stratum corneum conductance and skin pH were determined by biophysical methods to examine whether our patients exhibited changes in barrier function. Dermatophytosis and pityriasis versicolor except tinea pedis and tinea manus showed highly significant increase in TEWL compared with adjacent infection-free skin. Hydration was significantly reduced in lesional skin compared with adjacent infection-free skin. From this study, infections with dermatophytes and Malassezia species on the body can alter biophysical properties of the skin, especially the function of stratum corneum as a barrier to water loss. On the contrary, infections with dermatophytes on the palms and soles little affect the barrier function of the skin.

The application of topical MC to the resected bed of shave-removed ear keloids was successful in preventing recurrences and providing an acceptable cosmetic outcome.

The authors have indicated no significant interest with commercial supporters. D r. Norman Orentreich provided the scientific basis for the field of hair transplantation, stating that the transposed grafted skin maintains its integrity and that characteristics such as texture, color, growth rate, anagen period, and the majority of these transplanted grafts behave independent of the recipient site. 1 The concept of ''donor dominance'' that he discovered formed the foundation of hair restoration surgery. We suggested that the recipient site influences the growth characteristics of transplanted hairs such as growth rate and anagen period when transplanted scalp hairs were transplanted to different recipient sites such as the lower leg, neck, palm, hand dorsum, and eyebrow. 2,3 The purpose of this study was to evaluate whether the body hairs would keep their original growth characteristics when the body hairs were transplanted to the scalp area. Case ReportIn 2005, a patient with male pattern baldness gave his consent for this study. Donor hairs were harvested from the chest area and the occipital scalp using the elliptical excision technique. We transplanted nine chest hairs (single-hair follicular units) to the right side of the frontal scalp ( Figure 1A, yellow circle) and the occipital hairs to the vertex ( Figure 1A, blue circle) using a KNU implanter. We tattooed one point on the right frontoparietal recess where no residual terminal or intermediate hairs were growing and kept a copy of the transplanted points on the cellophane adhesive tape. One year after the operation ( Figure 1B), iris scissors were used to cut nine transplanted chest hairs from the scalp and 14 original chest hairs. The length and caliber of each cut hair was then measured. Hairs were cut as close to the skin surface as possible to measure total hair length grown for 1 year. After the hairs were cut, they were allowed to grow for 4 weeks, and the length of the hairs was again measured. The difference in the hair growth rate per 4 weeks of the transplanted chest hairs and original chest hairs was analyzed.The transplanted chest hairs grew longer than the original chest hairs, 56.3 mm versus 28.5 mm, about two-fold increase in mean length after the 1-year follow-up period ( Figure 2). The hair growth rate also increased slightly after transplantation from the chest to the scalp: 10.4 mm/4 weeks for the transplanted hairs to the scalp and 8.9 mm/4 weeks for the original hairs. Mann-Whitney U test was used to analyze the difference between the transplanted and original chest hairs, so the value of p was less than .05 in the mean length and hair growth rate. The transplanted chest hairs showed several different growth characteristics. However, there was no

Nevus sebaceous (NS) is a benign neoplasm occurring mainly on the face and scalp. It commonly occurs as a solitary, well-demarcated lesion. This paper presents a case of multiple nevus sebaceous, which presented as multiple lesions occurring on the temporal scalp and on the contralateral side of the chin. Multiple NS have only rarely been reported.
