Conjunctival melanoma is a rare malignant tumor with a recurrent character and metastatic potential. It is characterized in anatomopathology by a tumoral proliferation of atypical melanocytes. It can develop on a pre-existing lesion or appear on a healthy conjunctiva called "de novo" melanoma. The clinical aspect of melanoma is variable. It often appears as a pigmented lesion in relief, more or less nodular and vascularized, but it can also be achromatic. It can involve any portion of the conjunctiva and extend to the surface of the cornea. The involvement can be plurifocal.
