Dermoscopic Image Digital Post-Processing Perception and Use Among Members of the International Dermoscopy Society: Results of a Web-based Survey.

Introduction: Speculatively, digital image post-processing (DIPP) enhances diagnostic accuracy in dermoscopy.

Objective: We aimed to investigate the advantages and limitations of DIPP, as well as its perceived reliability and safety.

Methods: In this study we investigated the perception and use of DIPP among members of the International Dermoscopy Society through a web-based survey with 17 questions focusing on: (i) demographics (sex, age, nationality, specialty, professional experience in dermoscopy), (ii) application of digital dermoscopy, (iii) imaging devices, (iv) DIPP software usage, (v) area of DIPP application (e.

Reflectance confocal microscopy terminology for nonmelanocytic skin lesions: A Delphi consensus of experts.

Background: There is lack of uniformity in reflectance confocal microscopy (RCM) terminology.

Objective: To establish expert consensus on a standardized set of RCM terms that describe non-melanocytic lesions (NMLs).

Methods: We invited RCM experts to participate in a Delphi-consensus study.

The state of artificial intelligence-enabled skin cancer diagnostics: Why are there two spectroscopy devices available yet no imaging devices?

Artificial intelligence (AI) is already impacting the way we diagnose skin diseases. Although there are many new AI tools promoted to be helpful to dermatologists and primary care physicians, especially in the recognition of melanoma and nonmelanoma skin cancers, there is a major obstacle that the sponsoring companies must overcome before it is possible to integrate any of these innovative AI-enabled technologies into clinical practice. The regulatory process of the Food and Drug Administration (FDA) is demanding and requires proof of safety and effectiveness for each of these devices before the FDA gives their approval.

Baseline dermoscopic patterns predict long-term changes in nevus diameter and in dermoscopic features.

Background: When monitoring melanocytic neoplasms, the pattern of change may distinguish nevi from melanoma. Anticipating the growth dynamics of nevi based on their dermoscopic pattern is important to make this distinction.

Objectives: The primary aim was to examine the association between nevus dermoscopic pattern at baseline and diameter change during long-term monitoring.

Differentiating seborrheic keratosis from melanoma among lesions exhibiting blue-white veil: A retrospective study.

Background: Differentiating melanoma (MM) from seborrheic keratosis (SK) containing a blue-white veil (BWV) remains challenging.

Objective: Identify dermoscopic features that can improve upon the differentiation between MMs and SKs exhibiting BWV.

Methods: Images from 110 MMs and 121 SKs containing BWV were aggregated, and 91 MMs and 62 SKs from this data set had complete agreement on the presence of BWV according to 3 expert dermoscopists.

Lentigo Maligna Part II: Management.

Lentigo Maligna (LM) arises on chronically-sun damaged skin and can have extensive subclinical spread, often in functionally and cosmetically challenging areas. This two-part continuing medical education (CME) series reviews LM. Part I reviews epidemiology, risk factors, clinical presentation, diagnostic tools, biopsy technique, and histopathology of LM.

Lentigo Maligna Part I: Epidemiology, Risk Factors, and Diagnosis.

Lentigo maligna (LM) is an increasingly common subtype of melanoma, presenting as a slow-growing tan-brown macule or patch with irregular borders arising on chronically solar-damaged skin. This two-part continuing medical education (CME) series provides an overview of LM. Part I reviews LM's epidemiology, risk factors, and clinical presentation.

The Impact of Melanoma Imaging Biomarker Cues on Detection Sensitivity and Specificity in Melanoma versus Clinically Atypical Nevi.

Incorporation of dermoscopy and artificial intelligence (AI) is improving healthcare professionals' ability to diagnose melanoma earlier, but these algorithms often suffer from a "black box" issue, where decision-making processes are not transparent, limiting their utility for training healthcare providers. To address this, an automated approach for generating melanoma imaging biomarker cues (IBCs), which mimics the screening cues used by expert dermoscopists, was developed. This study created a one-minute learning environment where dermatologists adopted a sensory cue integration algorithm to combine a single IBC with a risk score built on many IBCs, then immediately tested their performance in differentiating melanoma from benign nevi.

Dermoscopic Features of Melanocytic Nevi in Cardiofaciocutaneous and Costello Syndromes.

Importance: Somatic variants in the RAS/MAPK pathway genes are commonly associated with melanocytic nevi and melanoma, whereas germline variants in these genes are associated with RASopathies, syndromes involving multiple organs, including the skin. Nevi counts may be higher in some RASopathies, but studies on features observed through dermoscopy are limited.

Objective: To determine the distinguishing dermoscopic features of melanocytic nevi and how the RAS pathway influences them by comparing nevi in patients with cardiofaciocutaneous syndrome (CFC) and Costello syndrome (CS).

Challenging Diagnosis of Basal Cell Carcinoma: A Case Report Emphasizing the Clinical Utility of Dermoscopy.

Dermatological conditions often present diagnostic challenges due to their diverse manifestations and overlapping clinical features. In such cases, dermoscopy, a non-invasive imaging technique, has emerged as a valuable tool to enhance diagnostic accuracy and guide clinicians in reaching an appropriate differential diagnosis. By visualizing subsurface skin structures and microvascular patterns, dermoscopy provides additional information that complements clinical examination, aiding in the recognition of specific dermatoses and the differentiation between benign and malignant skin lesions.

International Skin Imaging Collaboration-Designated Diagnoses (ISIC-DX): Consensus terminology for lesion diagnostic labeling.

Background: A common terminology for diagnosis is critically important for clinical communication, education, research and artificial intelligence. Prevailing lexicons are limited in fully representing skin neoplasms.

Objectives: To achieve expert consensus on diagnostic terms for skin neoplasms and their hierarchical mapping.

Risk factors and outcomes of melanoma in children and adolescents: A retrospective multicenter study.

Background: Pediatric melanoma presents with distinct clinical features compared to adult disease.

Objective: Characterize risk factors and negative outcomes in pediatric melanoma.

Methods: Multicenter retrospective study of patients under 20 years diagnosed with melanoma between January 1, 1995 and June 30, 2015 from 11 academic medical centers.

Continuing Medical Education-accredited reflectance confocal microscopy course in the USA and its impact on learning and clinical integration: report from a single centre.

Reflectance confocal microscopy (RCM) images skin lesions noninvasively at quasi-histological resolution. RCM has improved the diagnosis of skin neoplasms, and recently acquired billing codes in the USA. However, reading RCM images requires training, imposing a major barrier to its widespread adoption.

Full-body skin examination in screening for cutaneous malignancy: a focus on concealed sites and the practices of Australian dermatologists.

Background: Full-body skin examination (FSE) is a vital practice in the diagnosis of cutaneous malignancy. Precisely how FSE should be conducted with respect to concealed site inclusion remains poorly elucidated.

Objective: To establish the approach of Australian dermatologists to concealed site examination (CSE).

Perifollicular linear projections: A dermatoscopic criterion for the diagnosis of lentigo maligna on the face.

Background: Lentigo maligna (LM) can mimic benign, flat, pigmented lesions and can be challenging to diagnose.

Objective: To describe a new dermatoscopic feature termed "perifollicular linear projections (PLP)" as a diagnostic criterion for LM on the face.

Methods: Retrospective study on reflectance confocal microscopy and dermatoscopy images of flat facial pigmented lesions originating from 2 databases.
