Abstract:
A granular cell variant of a cutaneous basal cell tumor in a Wistar rat is described. The tumor resembles the variant as described in man and dogs. The granular basal cells contain cytoplasmic PAS positive granules, and immunostained positively with HMW cytokeratins. Ultrastructurally, the cytoplasmic granules were secondary lysosomes.
