Atypical lentiginous nevus
Diagnosis in short

LM DDx dysplastic nevus, melanoma in situ

Atypical lentiginous nevus, also atypical lentiginous nevus of the elderly, is a melanocytic lesion associated with old age and melanoma.

It can be considered a type of dysplastic nevus.[1][2]

General

Gross

  • Pigmented lesion.
  • Size: 0.3-1.0 cm.[4]

Microscopic

Features:[4]

  • Elongated rete ridges - key feature.
  • Superficial dermal fibrosis, diffuse (non-lamellar) - important.
  • Mild-to-moderated cytologic atypia.

DDx:[4]
