Abstract

OBJECTIVE: To report the spectrum of iris lesions based on patient age at presentation.

DESIGN: Retrospective, nonrandomized, single-center case series.

PARTICIPANTS: We included 3680 iris tumors in 3451 patients.

METHODS: Chart review.

MAIN OUTCOME MEASURES: Diagnostic category based on age.

RESULTS: The mean age at presentation was 48 years and there were 449 (12%) tumors in children (≤20 years), 788 (21%) in young adults (21-40 years), 1308 (36%) in mid adults (41-60 years), and 1135 (31%) in senior adults (>60 years). Of 3680 tumors, the diagnostic category was cystic (n = 768; 21%) or solid (n = 2912; 79%). The cystic tumors originated from iris pigment epithelium (IPE; n = 672; 18%) or iris stroma (n = 96; 3%). The solid tumors included melanocytic (n = 2510; 68%) and nonmelanocytic (n = 402; 11%). The melanocytic tumors comprised nevus (n = 1503; 60%), melanocytoma (n = 68; 3%), melanoma (n = 645; 26%), and melanocytosis (n = 64; 3%). Of 2510 melanocytic tumors, the first and second most common diagnoses by age (children, young adult, mid adult, senior adult) were nevus (53%, 57%, 63%, and 63%, respectively) and melanoma (17%, 27%, 26%, and 27%, respectively). The nonmelanocytic tumors included categories of choristomatous (n = 4;

CONCLUSIONS: In an ocular oncology practice, the spectrum of iris tumors includes cystic (21%) and solid (79%) tumors. The solid tumors were melanocytic (68%) or nonmelanocytic (11%). At all ages, the most common specific diagnoses were nevus (42%), IPE cyst (19%), and melanoma (17%).
