A lentiginous naevus (also called naevoid lentigo or ‘jentigo’) has few junctional nests and lentiginous melanocytic hyperplasia at the periphery (figure 6). A continuum may exist whereby lentigo simplex can evolve to form junctional then compound and finally intradermal naevi. Lentiginous melanoma is a proliferation of malignant pigment cells (melanocytes) along the basal layer of the epidermis.
The precursor lesion is an atypical solar lentigo or a lentiginous / junctional naevus. Acral lentiginous melanoma is a rare subtype of melanoma that appears on the palms, soles, or under the nails. It can arise in normal-appearing skin, or more rarely it can develop within an existing melanocytic naevus (mole). View pictures of acral lentiginous melanoma in the gallery below.
lentiginous junctional melanocytic, This rare subtype of melanoma can appear on the palms, soles, or under the nails. It can arise in normal-appearing skin, or more rarely it can develop within an existing melanocytic naevus (mole). What is acral lentiginous melanoma? Acral lentiginous melanoma is a type of melanoma arising on the palms of the hands, soles of the feet, or the underside of fingers or toes. What are the clinical features of acral lentiginous melanoma?
lentiginous junctional melanocytic, Acral lentiginous melanoma starts as a slowly enlarging flat patch of discoloured skin. Atypical melanocytic naevus, Atypical naevus, Atypical mole, Dysplastic naevus, Clark naevus, B-K mole. Authoritative facts from DermNet New Zealand.
