Melanocytic nevi are common benign skin lesions that arise from the proliferation of pigment-producing cells called melanocytes. These nevi can occur anywhere on the body, including the eyelids and canthus.
The prevalence of eyelid nevi is not well established, but they are thought to be relatively rare. However, because they can be cosmetically concerning and may mimic malignant tumors, it is important to recognize and properly manage them.
In summary, melanocytic nevi of the eyelid, including canthus, are relatively rare but can be cosmetically concerning and may mimic malignant tumors. Proper diagnosis and management are important to ensure the best possible outcome for patients.
