The frequency of nevus-associated melanoma (NAM) is widely variable among different reports. Recently, it has been estimated to be around 29% of all diagnosed melanomas. 1,2 The aim of this observational retrospective study was to analyze dermoscopic, reflectance confocal microscopy (RCM), and histologic features of a case series of 22 NAM. 2 | MATERIAL AND ME THODS We retrospectively reviewed a database recording the melanomas diagnosed in the Pathology Unit of Alcorcon Foundation Hospital between September 2011 and 2018, obtaining a total of 240 melanomas. In 45 of them (18.75%), an associated nevus was found, and we selected for the study 22 cases with good quality dermoscopic

The diversity and utility of laser procedures have increased over the recent years and nowadays, applications for medical and cosmetic reasons have increased considerably. Problematic intraoral and cutaneous hirsutisms have been described as a consequence of complex reconstruction usually after oncology surgery. We present three patients in whom hair removal laser was performed on grafts and flaps in different compromised anatomical areas: oral cavity, penis, and auricular pavilion. All three patients were men; in two of them the hairy graft was a consequence after oncologic surgery reconstruction whereas the third patient presented hair in his auricular pavilion after cochlear implant due to a congenital ear malformation. In all the patients, neodymium:yttrium, aluminum, garnet laser (Nd:YAG) (1,064 nm) laser was performed with excellent aesthetic and functional outcomes with only three sessions. Hair removal laser is a well‐accepted and effective method of achieving permanent decrease in hair density. Several lasers have been used successfully, including the long‐pulse Alexandrite (755 nm), the long‐pulse diode (810 nm), and the Nd:YAG laser (1,064 nm). There is currently no standard protocol for laser use on hairy grafts or flaps and there is limited published data regarding skin graft revision to enhance aesthetics and function.

Background/Objectives: Lentigo maligna is usually located on the face. Extrafacial lentigo maligna is less common, and diagnosis of early forms is very difficult. Confocal microscopy of facial and extrafacial lentigo maligna shares the same features (abundant dendritic cells and generalised atypical junctional thickenings) and helps us to identify the dermoscopic features of extrafacial lentigo maligna. Methods:We analysed dermoscopic and clinical features of 41 lesions diagnosed by confocal microscopy of extrafacial lentigo maligna confirmed on histology to identify dermoscopic signs of early lesions.Results: Erased areas on dermoscopy were the clue to diagnose early lesions. At the borders of these areas, very small, round or triangular structures were found. At the lesion periphery, dermoscopy revealed a fine reticular pattern that helped to identify them as a melanocytic lesion. A progressive increase of the number and size of erased areas was accompanied by the appearance of various angulated structures around them (angulated lines, zigzag structures or polygonal structures). Analysis of invasive lesions revealed very large erased areas containing white lines and atypical vascularisation. Conclusions:We have identified the dermoscopic early features and signs of progression by examining the dermoscopic and reflectance confocal microscopy findings of early and invasive extrafacial lentigo maligna.

ObjectiveTo assess the incidence of amyloidosis and trends therein in patients with spondyloarthritis (SpA) over a long period (17 years).MethodsAn observational retrospective population-based matched cohort study was conducted. All the admissions of patients with SpA, including ankylosing spondylitis (AS), psoriatic arthritis (PsA), arthritis associated with inflammatory bowel disease (SpA-IBD) and reactive arthritis (ReA), reported between 1999 and 2015, were analysed and a control group matched by age, sex and year of admission was selected. Incidence rates for amyloidosis were calculated. Generalised linear models were used for trend analysis and unconditional logistic regression for calculating crude and adjusted ORs (AOR) to assess the association between amyloidosis and SpA.ResultsThe study database contained data on 107 140 admissions in each group. Between 1999 and 2015, 792 patients in the SpA cohort (0.7% of all admissions) had a diagnosis of amyloidosis versus 68 in the non-SpA cohort (0.1%) (p<0.001). From 1999 to 2015, incidence rates of amyloidosis tended to decrease in the SpA cohort (−4.63%/year overall), while they increased in the Non-SpA cohort (+10.25%/year overall). We found strong associations of amyloidosis with all SpAs (AOR 10.4; 95% CI 8.2 to 13.3) and with each type studied (AORs 10.05 (7.84 to 12. 88) for AS, 9.5 (7.3 to 12.4) for PsA, 22.9 (16.6 to 31.7) for SpA-IBD and 10.1 (6.1 to 16.7) for ReA).ConclusionsIncidence of amyloidosis among patients with SpA has strongly decreased in Spain. Amyloidosis is most strongly associated with SpA-IBD while the strength of association with PsA and ReA is similar to that with AS.
