Item Interpratation and Adaptation of Dermoscopic Terminology to Our Language: Consensus Report of the Turkish Society of Dermatology Dermoscopy Working Group(GALENOS YAYINCILIK, 2013-01-01) Ozdemir, Fezal; Karaarslan, Isil Kilinc; Turk, Bengu Gerceker; Sahin, Sedef; Sahin, Mustafa Turhan; Oguz, Oya; Oztas, Murat Orhan; Arca, Ercan; Mansur, Tulin; Karabulut, Ayse Anil; Kacar, Nida``Dermoscopic Terminology Consensus Meeting{''} was held at Ege University Medical Faculty Dermatology Department on the 24th of February in 2012 with the aim of establishing a common language in the translation of the dermoscopic terminology in English literature into Turkish. In this article, the Turkish terminology in which the consensus was reached at that meeting is presented together with the definitions and representative images as a dictionary.Item Tumor-stage mycosis fungoides of the vulva successfully treated with local low-dose radiotherapy(WILEY-BLACKWELL, 2015-01-01) Bakar, Ozgur; Sahin, Sedef; Cetinozman, Fatma; Willemze, Rein; Tezcanli, Evrim; Cetin, Emel DikiciogluMycosis fungoides (MF) is the most common type of primary cutaneous T-cell lymphoma. According to the proposed guidelines for MF, skin-directed therapies are the treatment of choice for patients with limited stage disease. We present a case of early-stage MF, who progressed to tumor-stage MF during the postpartum period, showing a solitary ulcerated tumor on the vulva, which was successfully treated with local response-based, low-dose radiotherapy.Item Painless dells on the cheek(MEDKNOW PUBLICATIONS \& MEDIA PVT LTD, 2013-01-01) Duman, Deniz; Durmaz, Emel Ozturk; Cetin, Emel A.; Yazar, Sukru; Sahin, SedefItem Is this psoriasis or something else?(SCIENTIFIC SCHOLAR LLC, 2022-01-01) Duman, Deniz Demircioglu; Durmaz, Emel Ozturk; Demirkesen, Cuyan; Sahin, SedefA 38-year-old man presented with a history of intractable itchy eruption on the buttocks, present for the last 6 years. The lesions had gradually spread over time and did not respond to several topical steroids. Dermatological examination revealed a butterfly-shaped erythematous verrucous plaque, involving both buttocks and gluteal cleft {[}Figure 1], and peripheral guttate red-brown discrete papules {[}Figure 2]. Histologic examination of a punch biopsy specimen displayed orthokeratosis, follicular plugging, numerous oblique columns of parakeratosis called cornoid lamellae, extending at about 45 degrees from the surface ofItem Terra firma-forme dermatosis(MEDKNOW PUBLICATIONS \& MEDIA PVT LTD, 2012-01-01) Erkek, Emel; Sahin, Sedef; Cetin, Emel Dikicioglu; Sezer, EnginTerra firma-forme dermatosis is characterized by `dirty' brown-grey cutaneous patches and plaques that can simply be eradicated by forceful swabbing with alcohol pads. The pathogenesis has been attributed to abnormal and delayed keratinization. Although affected patients present with typical lesions, the disorder is not well-known by dermatologists. In this report, we describe two patients with terra firma-forme dermatosis in the setting of xerosis cutis and atopic dermatitis. From a clinical point of view, we lay emphasis on its unique expression and diagnosis/treatment. From a histological perspective, we highlight its resemblance to dermatosis neglecta and speculate on the role of `neglect' in a patient with seemingly adequate hygiene. The role of urea containing emollients in the development of this disorder remains to be determined.Item Retrospective analysis of melanoma patients who had undergone PET-CT examination(DERI ZUHREVI HASTALIKLAR DERNEGI, 2013-01-01) Bakar, Ozgur; Vardareli, Erkan; Sahin, Sedef; Yuksel, Selcen; Aksoy, TamerBackground and Design: Pet positivity was found in 21 (37.5\%) the incidence of melanoma is increasing significantly in Turkey and in the whole world. Thus, Positron Emission Tomography-Computed Tomography (PET-CT), which is being reimbursed by the government for the documentation of metastases of clinically suspicious patients with stages 1 b and higher, is becoming widely used. This study aims to analyze, the histopathological features of the tumors and the clinical and demographic data on melanoma patients who had undergone PET-CT examination for the screening of metastases. Materials and Methods: We collected data on 57 melanoma patients who had undergone PET-CT evaluation in the Nuclear Medicine Department between 2004 and 2011. On the basis of PET-CT positivity, we retrospectively analyzed SUV (Standard uptake value), demographic data, Breslow thickness, primary tumor location, presence of histopathologically documented ulceration, perineural, vascular and lymphatic invasion, and metastases detected by other screening methods as well as the proposed treatment modalities. Results: PET-CT positivity was found in 22 (39\%) patients. The mean Breslow thickness was 5.12 +/- 6.29mm., 1 patient (\%7) with <= 1mm, 5 (36\%) with 2-4mm and 8 patients (57\%) with >4mm of Breslow thickness had distant metastases. Statistically significant correlation was found between Breslow thickness and positive PET-CT findings. The distribution of the primary tumor site was 35.3\%left-sided, 25.5\%right-sided and 39.2\%on the midline. All patients with scalp involvement had distant metastases. There was no statistically significant correlation of PET-CT positivity with histopathologically proven ulceration and perineural, vascular and lymphatic invasion. Thirty-one percent positive correlation was found between Breslow thickness and SUV. Forty-five percent of PET-CT positive patients had metastases documented with other screening methods as well. All but 2 patients with distant metastases had undergone wide tumor resection and adjuvant chemotherapy or radiotherapy. Conclusion: PET-CT complementing conventional imaging methods gains much importance in the treatment planning for some selected high-risk melanoma patientsItem Secretan Syndrome: A Fluctuating Case of Factitious Lymphedema(QUADRANT HEALTHCOM INC, 2021-01-01) Demircioglu, Deniz; Durmaz, Emel Ozturk; Sezer, Engin; Sahin, SedefItem Lesson of the month 1: Sudden onset postural livedo reticularis, cyanotic toes and multiorgan failure(ROY COLL PHYS LONDON EDITORIAL OFFICE, 2014-01-01) Duman, Nilay; Sahin, SedefCholesterol embolisation syndrome (CES) is a rare but serious disease with high mortality caused by the formation of an embolus made up of cholesterol crystals from atherosclerotic plaques. Its clinical presentation is usually initially insidious and it often remains unrecognised because of its non-specific clinical presentation, which can cause delays in treatment and high mortality. The most common physical symptoms are cutaneous. We present a lethal case of CES to increase the awareness about this serious condition.Item Did Dermatological Hospital Referrals and Practice of Dermatologists Change in Between Pre-covid and Covid Era? A Short-term Preliminary Evaluation(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2022-01-01) Kavak, Ayse; Erfan, Gamze; Aydingoz, IkbalEsen; Demir, Figen; Tukenmez-Demirci, Guelsen; Biyik-Ozkaya, Dilek; Demircioglu, Deniz; Yilmaz, Murat; Karapicak, Rabia; Sahin, SedefObjective: In this descriptive study, we aimed to evaluate features of dermatology referrals before and after Covid-19 pandemic. Materials and Methods: The patients referred to dermatology outpatient clinics of Acibadem Group Hospitals in Istanbul between the time intervals 2019 March 1st and August 31st (Group G1) and 2020 March 1st and August 31st (Group G2) were included in this study. G1 and G2 groups were compared in terms of age, gender, mean duration of complaints, the most common five anatomic regions and the most common five dermatoses. Results: Referral rate after Covid-19 pandemic was decreased by 40\%. Face (p=.0013, OR= 1.20, 95\% CI=1.07-1.34), scalp (p=.02, OR=1.23, 95\% CI=1.02-1.48) and hand (p=.04, 95\% OR=1.24, 95\% CI=1.00-1.54) were more common locations in 2020 (group G2) than in 2019 (G2 group). The most common five dermatoses were contact dermatitis (8.3\%), acne (8,1\%), wart (7,0\%), seborrheic dermatitis (5,7\%) and pyoderma (5,5\%) in G1 (2019), while the order was contact dermatitis (10,6\%), acne (7,5\%), seborrheic dermatitis (6,5\%), wart (6,4\%) and pyoderma (4,9\%) in G2 (2020). Contact dermatitis showed a significant increase after pandemic (p=.0017, OR=1.29, 95\% CI=1.10-1.51). In 2020, psoriasis and lichen planus showed a two-fold increases (P <.001, OR=2.00, 95\% CI=1.43-2.79 and p=.03, OR=1.92, 95\% CI=1.09-3.38, respectively), whereas frequency of molluscum contagiosum decreased significantly (p=.03, OR=0.49, 95\% CI=0.26-0.92). Conclusion: Although we found some remarkable results, relatively short-term period design with the limited patient population of this study needs to be verified in more comprehensive studies.Item Childhood alopecia areata: A study of 89 patients(DERI ZUHREVI HASTALIKLAR DERNEGI, 2014-01-01) Dogan, Sibel; Ersoy-Evans, Sibel; Gonc, Nazli; Sahin, SedefBackground and Design: Alopecia areata (AA) is a frequent type of acquired hair loss with a sudden onset. The aim of this study was to investigate the epidemiological and clinical features of AA and diseases associated with AA in the Turkish pediatric population. Materials and Methods: We retrospectively evaluated the medical data of patients under 16 years of age who were admitted to the pediatric dermatology outpatient clinic at Hacettepe University Hospital between 2006 and 2011 with a diagnosis of AA, alopecia totalis (AT) and alopecia universalis (AU). Results: A total of 89 patients (34 females and 55 males), were included in this study. The mean age of the subjects was 9.8 +/- 3.4 years (range:18 months-16 years). 9\% (n=8) patients had other autoimmune diseases: Hashimoto's thyroiditis in 5, vitiligo in 1, juvenile rheumatoid arthiritis (JRA) in 1 and morphea in 1 patient. AA was located on the scalp in 86.5\% (n=77) of the patients, 7.9\% (n=7) of the patients had AA on the scalp together with eyelashes, eyebrows and the body. AT was noted in 1, AU was noted in 4 patients. Severity of hair loss was <25\% in 94.3\% (n=84) of the patients according to the involved area. Hashimoto's thyroiditis was diagnosed in 5 patients
