Abstract

AbstractPurpose To estimate the incidence of iris melanoma in Denmark from 1942‐2013 as well as the age distribution of the patients and specific location of the tumor.Methods Retrospective, nonrandomized clinical case series including all patients with a clincal diagnosis of iris melanoma over 71 years. For all patients age, sex and specific location were registered.Results From 1942‐2013 a total of 389 cases were registered and 353 cases were treated (173 males, 116 females). This means an average of 5.6 cases/year in an average population of 5 million. A significant increase in the number of cases was found during the study period. The mean age at presentation of the surgically removed iris melanoma was 56 years (range 7 – 92). There were 11 (3,12 %) tumours in children and teenagers (≤20 years), 58 (16,43 %) in young adults (21‐40 years), 117 (33,14 %) in mid adults (41‐60 years) and 167 (47,30 %) in seniors (> 61 years). Location was described in 167 cases with 143 cases (85 %) inferior and 24 (15 %) superior in the iris.Conclusion An increase in the incidence of iris melanomas in Denmark has been observed. In 85% of all cases the iris melanoma was located in the inferior part of the iris.
