Chondrodermatitis nodularis helicis in the 21st century: demographic trends from a gender and age perspective. A single University hospital retrospective histopathological register study of 215 patients in Asturias, North Spain (2000–2017)
Abstract
Chondrodermatitis nodularis helicis (CNH) is an exceptionally investigated disease1 . Male sex and old age characterize its demographic profile1-3 but this has not been recently investigated. With this aim, we performed this descriptive, retrospective, observational investigation including 215 patients histopathologically diagnosed of CNH at Central University Hospital of Asturias, northern Spain, (years 2000 to 2017). It was approved by the Hospital s ethics committee. Univariate analyses were conducted by chi square test and Fisher Test. A 2-sided P value of 0.05 was considered statistically significant (R program; R Development Core Team, version 3.6.0).
