They are tumors that appear in the conjunctiva, from the corneal edge to the conjunctival cul-de-sac. They can be benign or malignant, pigmented or not, and in some cases endanger the vision and life of the patient, so they require an early diagnosis to receive adequate treatment.

Treatment: Symptomatic benign tumors can be managed with periodic observation. Malignant tumors require small incision surgery, cryotherapy (freezing therapy), local chemotherapy, and in some cases radiation therapy.
