high frequency ultrasound ( hfus ) is a non - invasive technique that allows visualizing skin tumors in vivo to obtain size , shape and tumor volume . in this study , we sought to measure the correlation between ex vivo hfus and histopathology surgical margins of basal cell carcinoma . hfus was performed with a 22 mhz ultrasound ( taberna pro - medicum , lneburg , germany ) before and immediately after excision to determine length and depth . a total of 79 basal cell carcinoma ( bcc ) ( 56 nodular , 15 superficial and 8 with more than one histological subtype ) were included . out of 79 bcc , 76 ( 96.2% ) had a correspondence between ex vivo hfus and histology ( 72 had negative and 4 had positive sm by ex vivo hfus and histology ) . of the remaining 3 tumors , one had uncertain and 2 had negative sm by ex vivo hfus while positive sm by histology . in this study , ex vivo hfus allowed correct visualization of negative sm in 72/79 bcc ( 91.1% ) . other non invasive techniques such as dermoscopy and confocal microscopy allow an accurate diagnosis in most bcc cases . future studies are needed to compare ex vivo hfus with other non - invasive technique such optical coherence tomography and confocal microscopy . the international skin imaging collaboration is an academia / industry partnership designed to facilitate the application of digital skin imaging to help reduce melanoma mortality . the mobile era presents an exciting opportunity for the application of digital photography as an aid to early diagnosis of melanoma . isic is designed to address two barriers to the broad successful implementation of mobile solutions for melanoma diagnosis : a lack of standards for dermatologic imaging , and limited access of educators and developers to large numbers of high quality clinically annotated skin lesion images . working groups comprised of international melanoma thought leaders from academia and industry we are using the delphi method to propose standards related to 5 areas of skin cancer imaging : technology , terminology , techniques , privacy , and metadata . the working groups have prepared several publications to date that are in press and/or under review . it is hoped that the efforts of the working groups will serve as the basis for convening a successful dicom process for dermatologic imaging with an initial focus on melanoma . current efforts in melanoma education and automated diagnosis typically rely on convenience samples of small numbers of images that vary in quality and annotation . the isic archive is a partnership of leading international melanoma centers to provide a large public repository of clinically annotated high quality skin images . the isic archive software is open source and the images in the archive are publicly available through a creative commons zero license ( cc0 ) . the individual lesion images in the archive are annotated with clinical ( e.g. , pathology diagnosis ) and technical ( e.g. , exif header content ) attributes . in addition , a process has been developed to append morphologic annotations to the images at the lesion level ( e.g. , symmetry ) and at the sub - lesion level ( e.g. , the presence of pigment network in a specific region within a lesion ) . the initial focus of the archive and annotations has been on dermoscopic images , as these are most diagnostic for melanoma . the archive has been selected for an ongoing 20162017 image analysis challenge ( for automated lesion segmentation and classification ) by the international symposium of biomedical imaging .
what follows are the abstracts presented at the joint meeting of the international confocal group ( icg ) , the international dermoscopy society ( ids ) , and the international society for digital imaging of the skin ( isdis ) . 
 the meeting was held on march 5 , 2016 , in washington , dc , usa , in conjunction with the annual meeting of the american academy of dermatology ( figure 1 ) . 
 the abstracts appear in the order in which they were presented .
