A multimodal vision foundation model for clinical dermatology.
Abstract Diagnosing and treating skin diseases require advanced visual skills across domains and the ability to synthesize information from multiple imaging modalities. While current deep learning models excel at specific tasks such as skin cancer diagnosis from dermoscopic images, they struggle to meet the complex, multimodal requirements of clinical practice. Here we introduce PanDerm, a multimodal dermatology foundation model pretrained through self-supervised learning on over 2 million real-world skin disease images from 11 clinical institutions across 4 imaging modalities. We evaluated PanDerm on 28 diverse benchmarks, including skin cancer screening, risk stratification, differential diagnosis of common and rare skin [...]
In vivo reflectance confocal microscopy role for early to advanced lentigo maligna melanoma spectrum: A systematic review and pooled analysis.
Abstract Background: Lentigo maligna (LM) is a growing problem worldwide and the main type of melanoma in situ in some Caucasian populations. It presents as a spectrum from atypical intraepidermal melanocytic proliferation (AIMP) to invasive lentigo maligna melanoma (LMM). Accurate diagnosis and staging are crucial for determining appropriate management strategies. Objectives: To assess the role of in vivo reflectance confocal microscopy (RCM) in differentiating early and advanced stages of lentigo maligna. Methods: A systematic search was conducted on Medline, PubMed, Scopus, Web of Science, Proquest Central, Embase, Cochrane and Google Scholar. References of included and excluded studies were reviewed for additional sources. [...]

Mohs micrographic surgery for the treatment of invasive melanoma: A systematic review with meta-analyses.
Abstract Background: The use of Mohs micrographic surgery (MMS) in melanoma treatment has divided opinion and evidence-based guidelines are lacking. Objectives: This systematic review aimed to analyse clinical outcomes for patients with invasive melanomas treated with Mohs rather than wide local excision (WLE). Methods: Embase, MEDLINE and Cochrane databases (to 30 August 2023) were searched for studies using Mohs to treat invasive melanoma. Outcomes of interest were local recurrence and death from melanoma. Results: Thirty-five articles involving 41,499 patients with invasive melanoma treated with Mohs were identified. Sixteen studies compared Mohs with WLE and 19 were Mohs-only, non-comparative studies. Patients treated with Mohs [...]

Short-Term Effectiveness of a Stepped-Care Model to Address Fear of Cancer Recurrence in Patients With Early-Stage Melanoma.
Abstract Objective: To investigate the effectiveness of the Melanoma Care Programme when implemented into routine clinical practice coupled with fear of cancer recurrence (FCR) screening and a stepped-care model of intervention delivery. Methods: Using a Type-I hybrid effectiveness-implementation design, individuals with stage 0-II melanoma and a Fear of Cancer Recurrence Inventory FCR severity score of ≥ 13 were offered the Melanoma Care Programme. The programme included a psychoeducational booklet and 3 to 5 psychotherapeutic telehealth sessions with a clinical psychologist, timed around routine dermatological appointments. Multivariable linear mixed modelling was used to analyse the effect of the intervention at 1-week post-intervention [...]

Variation in initial biopsy technique for primary melanoma diagnosis: A population-based cohort study in New South Wales, Australia.
Abstract Background: Factors associated with nonadherence to guideline-recommended complete excision of suspicious cutaneous lesions are unclear. Objective: The purpose of this study was to analyze patient, melanoma, and clinician factors associated with initial diagnostic biopsy type and determine whether unwarranted variation from guidelines occurred. Methods: This population-based, cohort study involved the analysis of data from questionnaires completed by clinicians who managed patients with newly diagnosed, histopathologically confirmed primary invasive cutaneous melanomas reported to the New South Wales Cancer Registry between 2006 and 2007. Results: Of the 2267 biopsies, complete excision was attempted in 69.1% of cases but histologically incomplete in 14.0%. Multivariable regression [...]
Remote cutaneous confocal microscopy: A multicentric prospective study evaluating diagnostic accuracy for melanoma and keratinocyte carcinoma in tertiary settings.
Abstract Background: Cutaneous confocal microscopy (CCM) facilitates in vivo visualization of skin at a cellular level. Use of a "store and forward" approach for remote-CCM interpretation (remote-CCM) across multiple sites has not been tested and may increase access to noninvasive diagnosis. Objectives: To test the diagnostic accuracy and safety of remote-CCM. Methods: We prospectively recruited lesions selected for biopsy for skin malignancy across 5 Australian tertiary dermatology centers. CCM, clinical and dermatoscopy images were acquired prebiopsy and accessed by a cloud-based platform for interpretation by CCM readers. CCM diagnosis was compared with histopathology results. Results: Among the 201 lesions included, melanoma was the [...]
