Bases of pathological diagnosis of eyelid tumours

Purpose This presentation will discuss a variety of tumours of the eyelid and adjacent conjunctiva both clinically and histopathologically. Methods Clinical features of some "usual" and "unusual" tumours will be correlated with histopathologic findings. Results In many cases, the clinical diagnosis based on certain morphologic criteria and patient's history will be correct. However, it is not infrequent that only histopathologic examination will reveal the exact diagnosis and help to further manage the patient appropriately. Conclusion The correct diagnosis of eyelid lesions can usually be established using appropriate clinical features but histopathology is mandatory to confirm this since "surprises" are more frequent than we might assume.
