Palmoplantar lichen planus is a rare, localized variant of the disease that may create difficulty in diagnosis if it is present as an isolated finding. Although several morphological patterns may be seen, plaques or small papules with compact hyperkeratosis are usually observed. We present a 25-year-old woman with a one-month history of slightly pruritic, red papules on her palms and soles. Dermatologic examination revealed numerous, asymptomatic, unscaly, red papules on her palms and soles, some of them resembling vesicles and white reticulate plaques on both sides of the buccal mucosa. The diagnosis was established by the typical histopathological features of lichen planus. Although resistant to topical corticosteroids, she responded well to systemic corticosteroid therapy, and no recurrence was observed during the follow-up period of one year.

ÖzetAmaç: Seboreik dermatit, herpes zoster ve pitriyazis rozean›n ortak özellikleri hava ›s›s›n›n düflük oldu¤u dönemlerde görülme s›kl›klar›n›n artmas›d›r. Biz çal›flmam›zda seboreik dermatit, herpes zoster ve pitriyazis rozea'n›n y›l içinde aylar ve mevsimler ile olan iliflkilerini saptamay› amaçlad›k. Gereç ve Yöntem: Aral›k 2006 -Aral›k 2009 tarihleri aras›nda dermatoloji poliklini¤imize baflvuran 20397 hasta ve seboreik dermatit, herpes zoster ve pitriyazis rozea tan›s› alm›fl olan 1801 hasta otomasyon dosya sisteminden retrospektif olarak analiz edildi. Hastalar demografik verilere ve tan›lara göre grupland›r›ld›. Bulgular: Hastal›klar ile s›k görüldü¤ü mevsimler aras›nda istatistiksel olarak anlaml› iliflki tespit edildi (p<0,001). Seboreik dermatit %32,5 oran›nda sonbahar mevsiminde, herpes zoster %29,8 oran›nda sonbahar mevsiminde, pitriyazis rozea %31,0 oran›nda k›fl mevsiminde, tüm dermatolojik hastal›klar %29,1 oran›nda k›fl mevsiminde tespit edildi. Hastal›klar ile s›k görüldü¤ü aylar aras›nda istatistiksel olarak anlaml› iliflki tespit edildi (p<0,001). Seboreik dermatit %12,3 oran›nda kas›m ay›nda, herpes zoster %11,5 oran›nda eylül ay›nda, pitriyazis rozea %10,7 oran›nda ocak ay›nda, tüm dermatolojik hastal›klar %8,21 oran›nda flubat ay›nda tespit edildi. Sonuç: Çal›flma sonuçlar›m›z literatür bilgileri ile paralellik göstermektedir. Seboreik dermatit, herpes zoster, pitriyazis rozea ve tüm dermatolojik hastal›klar›n görülmesi aç›s›ndan sonbahar ve k›fl aylar› en yüksek oranda tespit edilmifltir. Ortam ›s›s›n›n düfl-mesi hücresel immun direncin deprese olmas›na neden olmakta, bunun da hastal›klara yatk›n bireylerde hastal›klar›n ortaya ç›k-mas›na ya da nüksüne neden oldu¤unu düflünüyoruz.

The aim of this study was to determine the relationships of seborrheic dermatitis, herpes zoster and pityriasis rosea with the months and sessions during the year. Material and Method: Twenty thousends three hundreds ninety seven patients referred to our dermatology policlinic between December 2006 and December 2009 with 1801 patients being diagnosed as seborrheic dermatitis, herpes zoster or pityriasis rosea were retrospectively analysed from the automation record system. The patients were grouped according to demographic data and diagnosis. Results: A statistically significant relationship was found between the diseases and the seasons in which they were frequently seen (p<0.001). It was found that 32.5% of seborrheic dermatitis was seen in autumn season, 29.8% of herpes zoster was seen in autumn season, 31.0% of pityriasis rosea was seen in winter season, and 29.1% of all dermatological diseases was seen in winter season. A statistically significant relationship was found between the diseases and the ...

Seborrhoeic dermatitis (SD) is a common chronic inflammatory skin disease. Although the exact pathogenesis of SD is unknown, Malassezia yeasts as well as genetic and environmental factors have been implicated. The aim of this study was to evaluate the efficacy of terbinafine 1% cream on SD lesions with face localisation. Thirty-five patients with SD were included in the study. Patients applied terbinafine 1% cream twice daily for four weeks. The severity of the signs (erythema, scaling, infiltration) was assessed using a 4-point score (0=absent, 1=mild, 2=moderate, and 3=intense) at baseline and at the 2nd and 4th weeks of the therapy. Also, self-assessment was done by the patients on a 100 mm visual analogue score (VAS) at each visit. Complete remission was observed in 10 (32.3%) patients at the end of the therapy. Statistically significant reductions in the scores of all parameters were observed at both the 2nd and 4th weeks of the therapy. Patients' self assessments in the 2nd and 4th weeks were similarly better than at the baseline.

SummaryBackground and Design: The aim of this study was to determine the distribution of skin diseases during childhood. Material and Method: A retrospective descriptive study was planned. Among 18318 patients referred to our dermatology outpatient clinic between September 2004 and November 2009, 1756 child patients between 0-12 years of age were retrospectively analyzed from automation record system. Results: A total of 1756 child patients who referred during the study period were included in the study; 791 patients were male (45.05%) and 965 were female (54.95%). The most frequently seen disease group was eczema (26.0%), followed by infectious dermatosis (20.6%) and eritematous squamous dermatosis (9.9%). Atopic dermatitis (8.0%), viral dermatosis (11.7%) and seborrheic dermatitis (7.1%) were the most frequently encountered diseases in eczema, infectious dermatosis and eritematous squamous dermatosis groups, respectively. Conclusion: We found that 56.5% of the diseases determined were composed of eczemas, infectious dermatosis and eritematous squamous dermatosis. (Turkderm 2010; 44: 132-7)

OBJECTIVES:The purpose of this study was to analyze the effects of soybean extracts obtained using different extraction methods on the skin of female rats.METHOD:A total of 64 female Sprague-Dawley rats were divided into 8 equal groups. Various extracts were administered to the female rats by oral gavage for one month. The groups comprised carboxymethyl cellulose-free control, carboxymethyl cellulose-plus control, 100-mg/kg n-hexane extract, 200-mg/kg n-hexane extract, 100-mg/kg ethyl acetate extract, 200-mg/kg ethyl acetate extract, 100-mg/kg ethanol extract and 200-mg/kg ethanol extract groups. The thickness of the collagen layer and the number of estrogen receptor-positive cells were evaluated.RESULTS:All the extract-treated groups showed a statistically significant decrease in the number of estrogen receptor-positive cells compared with the control groups. Regarding the thickness of the collagen layer, only the 200-mg/kg ethyl acetate extract-treated group showed a significant increase compared with the control groups (p<0.05).CONCLUSIONS:Our data suggest that oral intake of three different total soybean extracts might have positive estrogenic effects on the skin and that only a high-dose ethyl acetate extract can increase the expression of collagen, which may prove to be beneficial for postmenopausal facial skin.
