Précis

We document here an aggressive carcinoma arising in the conjunctiva of an anophthalmic socket, 41 years after enucleation for a sporadic, non-hereditary unilateral retinoblastoma. This tumor was treated for the first time with proton beam irradiation of the orbit. Investigations revealed an extensive metastatic spread to the loco-regional lymph nodes, requiring complementary parotidectomy, chemotherapy, and radiation therapy.

The incidence of conjunctival carcinoma arising in the bulbar conjunctiva peaks in Africa (3.4/100 000/year) and has been linked to factors contributing to its development, such as UV light exposure, as well as HIV or HPV infections [1]. On the contrary, carcinomas arising in the conjunctiva of anophthalmic sockets are extremely rare and, so far, only 23 cases have been documented, usually occurring a long time after enucleation. We document here the clinicopathological findings of a conjunctival carcinoma identified in the anophthalmic socket of a patient enucleated 41 years ago for a sporadic, unilateral retinoblastoma.
