BACKGROUND: @entity69659 ( @entity69659 ) is a common, underdiagnosed @entity272 . OBJECTIVES: The main objectives of this study were to determine the occurrence of @entity69659 relative to age and gender, to analyze its cutaneous distribution, and to investigate any possible familial basis for this condition, its impact on @entity1 , and the types and efficacy of previous treatments. METHODS: All @entity1 presenting to the outpatient dermatology clinic at the study institution and their relatives were examined for the presence of @entity69659 and were questioned about family history and previous treatment. Photographs and biopsies of suspected cases of @entity69659 were obtained. RESULTS: Of 2400 @entity1 seen between August and December 2013, 286 @entity1 were diagnosed with @entity69659 (135 males, 151 females; prevalence: 11.9%). @entity1 presented more frequently than @entity1 with complaints of @entity69659 (6.3 vs. 4.2%), and more @entity1 had received prior treatment for @entity69659 (10.5 vs. 2.8%). The most commonly affected sites were the face (100%), interscapular area (10.5%), and arms (3.1%). Lesions involved the nasal alae in 96.2%, the nasal tip in 90.9%, the chin in 55.9%, and the cheeks in 52.4% of @entity1 . Only 15.7% of @entity1 had @entity75 , and only 4.5% had @entity75 . Among the 38 previously treated @entity1 , 65.8% reported temporary improvement. CONCLUSIONS: @entity69659 is a common condition that predominantly affects the face in @entity1 of all ages. Additional studies employing larger cohorts from multiple centers will be required to determine the prevalence of @entity69659 in the general population.
