Second Primary Malignancies following a Diagnosis of Conjunctival Melanoma.

Patients with CM had an increased incidence of SPMs compared to the general population. Specifically, these patients developed more cutaneous, ophthalmic non-melanoma, and non-intrahepatic biliary malignancies. These second neoplasms could be due to shared pathophysiology or mutual risk factors. Patients with CM may benefit from surveillance for SPMs, such as annual age-appropriate screenings in the first 10 years after diagnosis.
