Removal of conjunctival nevus on a 4 year old. is it necessary or can wait until older?

Wait...: Nevi of the conjunctiva generally develop during the first 2 decades of life. In children, pure junctional nevi are common. In general, nevi of the conjunctiva are "benign" pigmented lesions of the ocular surface and are freely mobile over the surface of the globe. Unless a biopsy is required for ruling out malignant melanoma, a nevus is usually excised for cosmetic reasons only.
