Dermatoscopic features of extrafacial lentigo maligna.


The dermatoscopic features of classic lentigo maligna (LM) are well described; however, there is little literature available on extrafacial LM, which is a less frequently reported condition. The skin architecture is especially rich in adnexae on sun-exposed areas such as the face, relative to other parts of the body, thus it is possible that the dermatoscopic findings of extrafacial LM will differ from the usual findings of LM. We carried out a dermatoscopic study on three patients with extrafacial LM. The dermatoscopic patterns reflected the underlying histological features of the disease, with increased melanocytes seen along the rete ridges and around follicular ostia, which result in a unique pigment network architecture.
