IMPORTANCE Conjunctival tumors in children are usually benign and rarely malignant. OBJECTIVE To evaluate clinical features of conjunctival tumors in children by comparing benign tumors with their malignant counterparts. DESIGN, SETTING, AND PARTICIPANTS This retrospective case series reviewed 806 cases of conjunctival tumor in children (aged <21 years) who were evaluated at a tertiary referral center between November 1, 1975, and July 1, 2015. This study included 262 children who were part of a published review. MAIN OUTCOMES AND MEASURES Features of benign and malignant tumors were compared. Data were collected on patient demographics, tumor features, and specific diagnoses to determine findings related to each tumor. RESULTS Among the 806 patients with conjunctival tumor, the top 5 diagnoses included nevus (492 [61%]), benign reactive lymphoid hyperplasia (BRLH) (38 [5%]), nodular conjunctivitis (31 [4%]), dermoid (30 [4%]), and primary acquired melanosis (27 [3%]). Overall, conjunctival tumors were benign (779 [97%]) or malignant (27 [3%]), including melanoma (18 [2.2%]) and lymphoma (9 [1.1%]). The mean age at detection was 11 years for benign tumors and 14 years for malignant tumors (P = .005), with mean difference of 3 years (95% CI, 1.2-4.6). The relative frequency of any malignancy (per all conjunctival tumors) by age bracket (0-5 years, >5-10 years, >10-15 years, and >15-<21 years) was 1%, 2%, 3%, and 7%, respectively. A comparison between nevus and melanoma found differences with melanoma in the 10 to 15 years age bracket (29% vs 61%; difference of 32% [95% CI, 10%-55%];

We report a case of a newborn with unilateral retinal detachment that could not be repaired. At examination under anesthesia, the retina was markedly abnormal and a presumptive diagnosis of retinal dysplasia was made. Several years later, the eye was enucleated because it was blind and painful. Final pathology was consistent with familial exudative vitreoretinopathy (FEVR). The literature describing unilateral retinal dysplasia is sparse. This case adds to the clinical spectrum of pathologic findings in FEVR.
