The lesion is not fully excised so as we always remark we should be cautious on the report. I see an entirely dermal melanocytic proliferation with symmetrical silhouette, degenerative changes and angiectatic vessels. There is a banal nevus component at the periphery of the lesion and a central crowded more proliferative zone of spindle cells richly pigmented, without clear mitoses that matures in the deep portion. I find it hard to classify but I think I would call this a combined nevus banal and cellular blue/DPN. I ultimately favor benign based on the pictures alone.

Yes. Agree. There is a phenotypic heterogeneity: a plexiform Spitz component in the central area.
