Öğe Benign Neoplasms(CRC Press, 2022) Demirbaş, Abdullah; Elmas, Ömer Faruk; Akdeniz, NecmettinMost benign cutaneous neoplasms can be diagnosed clinically. If the diagnosis is uncertain clinically, especially when there have been unexpected changes in the appearance of the lesion, a biopsy is indicated. Lesions are small hyperpigmented macules with a diameter generally not exceeding 5 mm. The melanotic macule is a benign hyperpigmentation of mucous membranes found in about 3% of the general population. There is an increase in focal melanin accumulation without an increase in melanocytes. The most important differential diagnosis of acquired melanocytic lesions is melanoma. Histologically, lesions differ from melanoma by having small nucleolus of the melanocytes, absence of atypical mitoses, uniformity of cells, normal maturation, and nesting. Destructive methods, such as cryotherapy, curettage, laser, shave excision, electrocautery, and chemical peels, can be performed for aesthetic purposes. Moles are a common finding that require intervention only when there is concern for a malignancy or when they are cosmetically unacceptable. © 2022 Taylor & Francis Group, LLC.Öğe Calcinosis Cutis in Association With Long-term Stasis After Electrical Burn Injury: a Case Report(Mattioli 1885, 2022) Uyar, Belkiz; Elmas, Ömer Faruk; Acar, Emine Müge; Has, Sümeyra[No abstract available]Öğe Potential utility of oral mucosal capillaroscopy as an indicator of microvascular damage in Behçet disease: A preliminary study(Mattioli 1885, 2021) Demirbaş, Abdullah; Elmas, Ömer Faruk; Demirbaş, Gözde Ulutaş; Atasoy, Mustafa; Türsen, Ümit; Lotti, TorelloIntroduction: Behçet disease (BD) is an auto-inflammatory condition characterized by multisystemic vasculitis. Oral mucosal capillaroscopy is an easy-to-use, repeatable, non-invasive method for evaluating mucosal microvasculature, contributing to the differential diagnosis and prognosis of various acute and chronic inflammatory diseases. Objectives: This study aims to characterize and describe the oral labial mucosal capillary findings in patients with BD using handheld dermatoscopy and to investigate the relationship between the capillary findings and the severity of the disease. Methods: This cross-sectional study included patients with BD and healthy subjects. Capillaroscopic examination of the oral labial mucosa in each subject was performed by a handheld dermatoscope using polarized light. The clinical severity of BD was evaluated using Krause's Clinical Severity Scoring for BD. Results: Sixty patients with BD and 60 healthy subjects were enrolled in the study. The frequencies of irregular capillaries, microhemorrhages, glomerular vessels, megacapillaries, and tortuous vessels were statistically significantly higher in the patient group when compared to the healthy individuals. In addition, a correlation was detected between the oral mucosal capillaroscopic findings and disease duration, severity, and vascular complications. Conclusions: Our study is the first to explore the potential role of oral mucosal capillaroscopic examination in patients with BD. Data obtained from this study indicated that oral mucosal capillaroscopy may be a useful tool to demonstrate microvascular damage in patients with BD. © 2021 Demirbaş et al.Öğe Relationship between rosacea and chronic obstructive pulmonary disease: Rosacea and comorbidities(John Wiley and Sons Inc, 2022) Demirbaş, Abdullah; Yümer, Yusuf; Elmas, Ömer Faruk; Ulutaş Demirbaş, Gözde; Atasoy, Mustafa; Türsen, Ümit; Dursun, RecepBackground: Rosacea is a chronic inflammatory skin disease that has been reported to be associated with many systemic disorders including respiratory diseases. Aims: This study aims to investigate respiratory function in patients with rosacea. Patients/Methods: Patients with rosacea and age- and gender-matched healthy volunteers were included in this cross-sectional study. Spirometric pulmonary function tests including the percentage of forced vital capacity (FVC%), percentage of forced expiratory volume in one second (FEV 1%), forced expiratory flow at 25–75% of FVC (FEF 25–75%), and FEV 1/FVC ratio was assessed in both patient and controls. The potential relationship between rosacea severity and pulmonary functions was assessed. Results: A total of 120 patients with rosacea and 120 healthy controls were enrolled in the study. Compared to the controls, FEV 1%, FEV 1/FVC%, and FEF 25–75% values were significantly lower in patients with rosacea. Lower FEV 1/FVC% values were found to be associated with disease severity. FEV 1%, FEV 1/FVC%, and FEF 25–75% values were found to be more useful in differentiating the patients from healthy subjects. Conclusions: This study showed that patients with rosacea may have abnormal respiratory function compared to healthy subjects. Besides, disease severity was associated with worse respiratory functions. We believe that patients with rosacea, particularly those with additional risk factors, should be screened for respiratory disorders. © 2021 Wiley Periodicals LLC.Öğe The role of dermoscopy in diagnosis: A case presentation of pseudoxanthoma elasticum initially misdiagnosed as pigmented contact dermatitis(Mattioli 1885, 2021) Elmas, Ömer Faruk; Demirbaş, Abdullah; Kılıç, Raşit; Kilitçi, Asuman[No abstract available]
