[Suspicious conjunctival lesions]

The main conjunctival tumors are represented by (i) conjunctival melanoma, ocular surface squamous neoplasia, and conjunctival lymphoma, which are malignant tumors, and (ii) conjunctival nevus, papilloma, and choristoma, which are benign. In usual practice, ophthalmologists need to know how to differentiate conjunctival melanomas and carcinomas from the other conjunctival tumors by clinical examination. Indeed, the therapeutic approach to these two malignant diseases presents a number of particularities such as the need for surgery under general anesthesia, if possible, to minimize the risk of local dissemination and further local recurrence, and detailed information on the tumor location and measurements before surgery (Figures, diagram, sizes) to precisely define the irradiation field during complementary radiotherapy. The clinical signs and main therapeutic principles of conjunctival tumors are reviewed in this article.
