AFIP Images

Symmetrical lesion shows maturation of lesional cells in the dermis with attenuated single cells
among reticular dermis collagen bundles at the base but unlike desmoplastic melanoma, the
intraepidermal component does not extend substantially beyond the dermal component and
there are no clusters of mitotically active epithelioid melanocytes in the superficial dermis
