(A) Histopathological examination shows a raised, well-circumscribed, slightly asymmetric dermoepidermal atypical melanocytic proliferation associated with marked hyperkeratosis and irregular hyperplasia (H&E, original magnification ×2.5). (B) There is prominent central and lateral pagetoid spread of melanocytes and no epidermal ulceration (H&E, original magnification ×10). (C) Pigmented melanocytes display an epithelioid spindle (spitzoid) morphology and are mostly arranged in confluent fascicles with peripheral retraction artifacts (H&E, original magnification ×20). (D) Melanocytes show mild pleomorphism and are intermingled with numerous melanophages (H&E, original magnification ×40). H&E = hematoxylin and eosin. [Copyright: ©2019 Bassi et al.]
