    In Vivo and Ex Vivo Confocal Microscopy for Dermatologic and Mohs Surgeons.
    Dermatol Clin 2016 Oct;34(4):497-504
    Melanoma Unit, Dermatology Department, Hospital Clinic and Institut d'Investigacions Biomediques August Pi I Sunyer, Barcelona, Spain.
    Confocal microscopy is a modern imaging device that has been extensively applied in skin oncology. More specifically, for tumor margin assessment, it has been used in two modalities: reflectance mode (in vivo on skin patient) and fluorescence mode (on freshly excised specimen). Although in vivo reflectance confocal microscopy is an add-on tool for lentigo maligna mapping, fluorescence confocal microscopy is far superior for basal cell carcinoma and squamous cell carcinoma margin assessment in the Mohs setting.

    Department of Dermatology, Sheba Medical Center, Tel Hashomer, Ramat Gan 5262000, Affiliated with the Sackler School of Medicine, Tel Aviv University, Ramat Gan 52621, Israel.
    The clinical diagnosis of tumors on the curved surfaces of the face, around the eyes, and on the mucosal surfaces can be difficult, while biopsies and excisions can have functional and aesthetic consequences. To avoid unnecessary surgery, clinicians have been aiming to attain accurate noninvasive diagnosis of lesions at these sites. However, acquisition of high-quality images with dermoscopy and with traditional wide-probe reflectance confocal microscopy (WP-RCM) have been hampered with technical difficulties. Read More

    Lentigo Maligna, Macules of the Face, and Lesions on Sun-Damaged Skin: Confocal Makes the Difference.
    Dermatol Clin 2016 Oct;34(4):421-429
    Dermatology, Sydney Melanoma Diagnostic Centre (SMDC), Royal Prince Alfred Hospital, Melanoma Institute Australia, Central Clinical School, Sydney University, Missenden Road, Camperdown, New South Wales 2050, Australia. Electronic address:
    Distinguishing lentigo maligna (LM) and lentigo maligna melanoma (LMM) from background pigmented non-melanoma lesions is challenging. The field of solar damage can obscure clinical assessment, and diagnostic ambiguities are created due to the overlap of the clinical features of LM with other benign lesions. Moreover, margin assessment on histology is limited by the resemblance between melanocytic hyperplasia of actinically damaged skin and scattered atypical melanocytes of LM/LMM. Read More
