Abstract
Two cases of compound melanocytic nevi with granular cell changes were studied. Histological examination revealed compound melanocytic nevi with a portion of the dermal component exhibiting a sheet like proliferation of nevoid cells with granular cytoplasm. Immunohistochemically, both populations of cells stained positive for S-100 and Melan-A. However, HMB-45 was positive only for the nevus cells with granular cytoplasm. We believe this represents granular cytoplasmic changes of nevus cells and does not denote malignant transformation.
