Conjunctival Compound Nevus

Preferred Label : Conjunctival Compound Nevus;

NCIt definition : A compound nevus that arises from the conjunctiva. It usually occurs in the bulbar conjunctiva, caruncle, and plica semilunaris. It is characterized by the presence of nevus cells within the epithelium and in the substantia propria. Type A nevus cells are present in the junctional nests and superficial substantia propria, and type B nevus cells are present in the deeper layers of the subepithelial compartment.;
