BACKGROUND Nodular lesions pose diagnostic challenges because nodular melanoma may simulate all kinds of melanocytic and nonmelanocytic lesions. Reflectance confocal microscopy (RCM) is a novel technique that allows visualization of the skin at nearly histological resolution although limited laser depth penetration hampers visualization of the deep dermis.(More)
BACKGROUND Fluorescence confocal microscopy (FCM) is an emerging technology for rapid imaging of excised tissue, without the need for frozen- or fixed-section processing. Basal cell carcinomas (BCCs) can be detected in Mohs excisions although few studies have described the major BCC findings as seen on FCM. OBJECTIVES To describe the major BCC findings of(More)
BACKGROUND The current guidelines for the management of basal cell carcinoma (BCC) suggest a different therapeutic approach according to histopathologic subtype. Although dermatoscopic and confocal criteria of BCC have been investigated, no specific studies were performed to evaluate the distinct reflectance confocal microscopy (RCM) aspects of BCC(More)
BACKGROUND Lichen planopilaris (LPP) and discoid lupus erythematosus (DLE) are the most common causes of lymphocytic primary cicatricial alopecia. The management of scarring alopecia can be difficult. The combination of clinical, dermoscopy and reflectance confocal microscopy (RCM), a noninvasive, high-resolution imaging technique, examinations have already(More)
Dermoscopy has become an integrative part of the clinical examination of skin tumors. This is because it significantly improves the early diagnosis of melanoma and non-melanoma skin cancer (NMSC) including basal cell carcinoma and keratinocyte skin cancer compared with the unaided eye. Besides its value in the noninvasive diagnosis of skin cancer,(More)
Mohs micrographic surgery can be employed in recurrent basal cell carcinoma, although it is a time-consuming technique. Recently, ex vivo fluorescence confocal microscopy (FCM) has been employed to obtain a fast assessment of tumor margins at the bedside. In our case we successfully employed ex vivo FCM to assess the tumor margins and we treated the(More)
BACKGROUND Dermoscopic classification of acquired melanocytic nevi (AMN) is based on the evaluation of 3 main criteria-global pattern, pigment distribution, and color. OBJECTIVE To determine whether these features are different in AMN in white people with different skin types (STs) according to the Fitzpatrick classification. DESIGN Digital dermoscopic(More)
In addition to its traditional use for the evaluation of skin tumors, dermoscopy continuously gains appreciation in other fields of dermatology. The patterns of several inflammatory and infectious skin diseases have already been described, and dermoscopy has been shown to improve the clinical diagnostic performance in the daily practice. The increasing use(More)
BACKGROUND Small-diameter melanocytic lesions represent a diagnostic challenge for clinicians, as they do not follow the ABCD rule for diagnosis and do not always display reliable histopathological criteria. OBJECTIVES To analyse the confocal features of small-diameter lesions (naevi and melanomas with diameter ≤ 5 mm) to determine whether they show(More)
