title: Histopathology of orbito-ocular diseases seen at University of Benin Teaching Hospital, Benin City.
abstract: Ninety-three biopsied lesions of the orbito-ocular region seen over a fifteen year period at the Pathology department of the University of Benin Teaching Hospital (UBTH) Benin City were reviewed. The aim was to determine the morphological patterns and the age, sex and site distribution of these lesions. Majority of the lesions (43.3%) were found in children less than 15 years of age. There was no difference in frequency between the two sexes. 41.9% of the lesions were malignant while 58.1% were benign. The commonest site of orbito ocular lesions was conjunctival (55.9%), followed by intraocular lesions (24.7%). About 50% of the lesions of the orbit were inflammatory pseudotumours. Inflammatory pseudotumours also formed the majority (33.3%) of the lesions in the eyelid. However, squamous cell carcinomas were the commonest lesions of the conjunctiva seen accounting for 25% of these. Retinoblastomas formed 95.7% of the intra-ocular tumours seen.
