[Epithelial tumors of the corneal limbus]

Corneal epithelial tumours are represented by intraepithelial carcinoma, invasive carcinoma and exceptional by melanic tumours with start point in intraepithelial melanocytes, 20 cases of epithelial tumours of epithelial limbus hospitalised in 3 years period, which represented 0.28% of patients, have been studied. Anatomopathological exam shows in 12 cases spinocellular carcinomas, in 2 cases basal cell carcinomas, in one case undifferentiated carcinoma in one case intraepithelial carcinoma and in 4 cases intraepithelial dysplasias. Limbus epithelioma is a very low penetrance tumour, the Bowman membrane being resisting and difficult to surpass. They have a great proliferative power. The tumour ablation with local diathermocoagulation was practiced, and postoperative contact radiotherapy has been done. In a single case a local recidive appeared and in another case the enucleation was practiced, because the tumour entered the ocular globe.
