Background: Melanomas on chronically sun-damaged skin (CSDS) can be difficult to identify and often manifest morphologic features that overlap with benign lesions., Objective: We describe and analyze the clinical and dermoscopic characteristics of melanomas on nonfacial CSDS., Methods: Melanoma cases on nonfacial CSDS were retrospectively identified from the biopsy specimen logs of 6 melanoma clinics. Clinical and dermoscopic images were combined into 1 database. Demographics, clinical, dermoscopic, and histopathologic information were analyzed. Descriptive frequencies were calculated., Results: One hundred eighty-six cases met the inclusion criteria: 142 melanomas in situ (76%) and 39 invasive (21%; mean thickness, 0.49 mm). Lentigo maligna was the most common histopathologic subtype (n = 76; 40.9%). The most frequent dermoscopic structures were granularity (n = 126; 67.7%) and angulated lines (n = 82; 44%). Vascular structures were more frequent in invasive melanomas (56% vs 12% of in situ melanomas). Most manifested 1 of 3 dermoscopic patterns: patchy peripheral pigmented islands, angulated lines, and tan structureless with granularity pattern., Limitations: This was a retrospective study, and evaluators were not blinded to the diagnosis. In addition, interobserver concordance and sensitivity and specificity for dermoscopic structures were not evaluated., Conclusion: Outlier lesions manifesting dermoscopic structures, such as granularity, angulated lines, or vessels and any of the 3 described dermoscopic patterns should raise suspicion for melanoma., (Copyright © 2015 American Academy of Dermatology, Inc.

Background: The Skin Cancer College of Australia and New Zealand (SCCANZ) has developed a unique project named SCARD - the Skin Cancer Audit and Research Database. Designed initially as a self-audit tool for primary care skin cancer practitioners, SCARD acts as a tracking tool to enhance practice safety, and it also creates practice performance reports. Pooling of de-identified data enables participating practitioners to confidentially compare their own practice to that of their peers. Additionally, this creates a large database with significant research potential, as SCARD records for every lesion de-identified practitioner and patient data, and extensive details of location, provisional and histological diagnosis, and the procedure(s) performed in its treatment., Methods: Preliminary data collected in the database have been presented in this study., Results: An initial pool of data from 177 practitioners contains 77,553 specimens from 41,006 individual patients., Conclusions: The data presented are being analyzed for further studies, and additional data continues to be collected from this ongoing project. SCARD is a useful tool at practice level, and substantial uptake by Australian primary care skin cancer practitioners has provided a unique opportunity for research into skin cancer and its management. SCCANZ, a professional college of predominantly primary care medical practitioners, with a commitment to the management of skin cancer in Australia and New Zealand, has formed a partnership with the School of Medicine at the University of Queensland to ensure that these data are managed and analyzed appropriately., (© 2011 The International Society of Dermatology.)
