Methods: Seven-hundred twenty geriatric outpatients admitted to the dermatology clinic, between the June 2012-June 2013, conducted to our study. Data of patients, which were collected from patient registry records on hospital computer automation system, were analyzed retrospectively.Results: A total of 820 dermatological diseases in geriatric patients were analyzed in 13 groups. The five most frequently encountered diseases were eczematous dermatitis 32.9%, senile pruritus 14.6%, superficial fungal infections 14.5%, urticarial diseases 7.4%, and benign and malign skin tumors 5%, respectively.Conclusion: As a result, we suggest, successful diagnosis and treatment of frequent dermatological diseases of elderly are important for health and life quality of patients.
