Lentigo maligna - anatomic location as a potential risk factor for recurrences after non-surgical treatment.

Background: A higher incidence of lentigo maligna (LM) recurrences on the nose was previously observed in our cohort after non-surgical treatment.

Objectives: To determine histological parameters that might be related to the previously observed higher incidence of LM recurrences on the nose after non-surgical treatment.

Methods: We randomly selected 22 surgical specimens of LM on the nose and 22 on the cheek.
