Fig. 1: Mixed and “dissoved” nests in BIMT.
From: Novel insights into the BAP1-inactivated melanocytic tumor

Remnants of conventional nevus with congenital features showing the splaying of melanocytes between collagen bundles (asterisk). Note the BAP1-inactivated epithelioid cells merging with conventional melanocytes wrapping around the nests, resulting in mixed nests composed of both conventional melanocytes and epithelioid cells (arrow) (A). Mixed nests composed of both BAP1-inactivated and BAP1-positive conventional melanocytes at the junction (B). A nest composed of exclusively BAP1-inactivated epithelioid melanocytes infiltrated by lymphocytes resulting in a dyscohesive growth pattern (“dissolved” nest) (C).
