Two Cases of Lentigo Maligna with Atypical Clinical Presentation / 대한피부과학회지

ABSTRACT

Lentigo maligna is a variant of melanoma in situ that appears on sun-exposed areas as a macule with variegated pigmentation and irregular borders. If untreated, it has a risk of progressing to lentigo maligna melanoma. Two patients presented with hyperpigmented macules or patches on atypical facial areas. The histological findings were consistent with lentigo maligna. An 80-year-old Korean woman presented with clustered hyperpigmented macules on the lower lip and oral mucosa, and a 45-year-old Caucasian presented with a lesion located on the external auditory meatus, with intermittent sun exposure. Herein, we report two interesting cases of lentigo maligna with atypical clinical presentations.
