• acral Spitz nevi
  30 April

  Spitz nevi on acral sites are rare and poorly documented. The combination of Spitzoid cytomorphology and atypical architectural features of the junctional component may lead to an erroneous diagnosis of melanoma.
  Acral Spitz nevi is characterized by strong and diffuse P16 and P21 expression, which differs from acral nevi and acral lentiginous melanoma.
  Acral Spitz nevi are a distinctive subgroup of Spitz nevi with benign behavior.
