The lesion shows a plexiform growth of amelanotic spindle cells with bulbous nodular growth into the superficial subcutis (hematoxylin and eosin-stained section). B, The bulbous nodule is composed of a dense proliferation of fusiform melanocytes. C, The melanocytes are immunoreactive for ALK. D, FISH confirms the ALK rearrangement.
