Orbital space-occupying lesions in Indian children.

Purpose: To present a review of all patients younger than 16 years who presented to us with orbital space-occupying lesions.
Methods: Retrospective case study.
Results: We analyzed the records of 119 children younger than 16 years of age who had presented to us with proptosis during the 10-year study period. Myogenic tumors were the most common lesion seen (24%), followed by metastatic and secondary orbital tumors (17%), vasculogenic lesions (15%), cystic lesions (10%), inflammatory lesions simulating tumors (7.5%), optic nerve and meningeal tumors (7.5%), peripheral nerve tumors (5%), lacrimal fossa lesions (4%), lymphoid tumors and leukemias (2.5%), primitive neuroectodermal tumors (3%), and others (2.5%).
Conclusion: We analyzed the profile of orbital lesions that underwent surgical procedures and were proven histopathologically. We found 63 malignancies among the 119 cases, for a malignancy rate of 53%. Orbital rhabdomyosarcoma and retinoblastoma with orbital spread were the most common causes of proptosis among the children.
