Clinicopathological analysis of 719 pediatric and adolescents’ ocular tumors and tumor-like lesions:a retrospective study from 2000 to 2018 in China

摘要

AIM:To describe the clinicopathologic features and classification of pediatric and adolescent ocular tumors and tumor-like lesionsMETHODS:A total of 719 cases of pathologically confirmed ocular tumors and tumor-like lesions in a pediatric population from two academic institutions over an 18-year period were retrospectively analyzed.The main outcome measures were the clinical and pathological features of the cases.RESULTS:Benign tumors accounted for 92.1%of all cases while malignant tumors accounted for 7.9%.The most common ocular benign tumors were(epi-)dermoid cysts(19.8%),nevi(15.2%),corneal dermoid tumors(9.8%),and calcified epitheliomas(8.8%).The most common ocular malignant tumors were retinoblastoma(80.8%),and rhabdomyosarcoma(3.9%).Eyelid and ocular surface tumors comprised 73.3%of benign tumors while intraocular and orbital cavity comprised 94.2%of malignant tumors.For tumor site,the upper eyelid was up to 1.79 times more than lower eyelid(P<0.05).Age at surgery and sex also had an association with different lesions(P=0.006,P=0.035,respectively).CONCLUSION:Most ocular tumors and tumor-like lesions in children and adolescents are benign.Pediatric ocular tumors are distinct from those in adults in terms of histological origin.(Epi-)dermoid cysts are the most common benign tumors while retinoblastomas the most common malignant tumors.
