Summary: The aim of this study was clinical and histopathological evaluation of benign tumors of the visual organ in 73 children treated in the Department of Pediatric Ophthalmology Medical University of Łódź between 1999 and 2005. The patients aged between 2 months and 16 years were divided into three age groups: 0-3 years, 4-8 years, 9-18 years. All children underwent complete ophtalmological examination supplemented by ultrasonography examination. In selected cases color Doppler ultrasonography and computerized tomography were implemented. The excised tumors underwent histopathological evaluation.
In all cases, the neoplastic changes developed unilaterally. In the examined age groups, benign tumors occurred respectively in 32.9%, 27.4% and 39.7% of the analyzed children. Before 4 years of age, the tumors developed in the orbital cavity (77.8%) and corneal limbus (50%). The tumors of lacrimal apparatus (100%), bulbar conjunctiva (77.8%) and eyelid (71%) were mostly observed in children of 3 and more years of age. The changes were most often localized in the eyelid (42.5%) and bulbar conjunctiva (24.7%).
Histopathological examination most often revealed pigmented nevi (30.1%), dermoids (24.7%) and haemangiomas (12.3%). The majority of the analyzed tumors included pilomatricoma (8.2%), dermolipoma (8.2%) and papilloma (6.9%).
Pigmented nevi concerned mostly bulbar conjunctiva (36.4%) and lacrimal system (27.3%). Their development occurred mostly in children aged 3 and more (95.5%). Dermoids were mainly localized in the conjunctiva (44.4%), orbital cavity (22.2%) and corneal limbus (22.2%). In the majority of cases (66.7%) those lesions revealed within the first three years of life. Capillary hemangiomas occurred in the first year of life and concerned orbital cavity (55.6%) and lower eyelid (44.4%).
There is a wide spectrum of benign tumors occurring in the visual organ in the developmental age. The histopathological profile of the tumors correlates with the age and localization in the visual organ.
