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 conditions, lesion segmentation, longitudinal monitoring, and metastasis prediction and prognosis. PanDerm achieved state-of-the-art performance across all evaluated tasks, often outperforming existing models when using only 10% of labeled data. We conducted three reader studies to assess PanDerm’s potential clinical utility. PanDerm outperformed clinicians by 10.2% in early-stage melanoma detection through longitudinal analysis, improved clinicians’ skin cancer diagnostic accuracy by 11% on dermoscopy images and enhanced nondermatologist healthcare providers’ differential diagnosis by 16.5% across 128 skin conditions on clinical photographs. These results show PanDerm’s potential to improve patient care across diverse clinical scenarios and serve as a model for developing multimodal foundation models in other medical specialties, potentially accelerating the integration of artificial intelligence support in healthcare.

TL;DR

PanDerm is a multimodal dermatology foundation model pretrained via self-supervised learning on over 2 million real-world skin images from 11 institutions across 4 imaging modalities. Across 28 benchmarks and 3 reader studies, it achieved state-of-the-art performance and improved clinician and nondermatologist diagnostic accuracy in several tasks.

Key findings

  • Pretraining used 2,149,706 unlabeled multimodal skin images: 757,890 (35.3%) TBP tiles, 537,047 (25.4%) dermatopathology tiles, 460,328 (21.4%) clinical images and 384,441 (17.9%) dermoscopic images. PanDerm achieved state-of-the-art performance on all 28 evaluated tasks, often using only 5–10% of labeled training data; it outperformed SwAVDerm using 33% less training data and reached best performance in 200 epochs versus 500–800 for MILAN, DINOv2 and MAE.
  • Diagnostic gains averaged 5.1%, 8.0%, 4.2% and 0.9% on dermoscopic, clinical, TBP and pathology datasets, respectively. On HAM10000 and PAD-UFES-20, PanDerm surpassed the next-best models by 4.7% and 9.0% (both P < 0.001). For broader skin conditions, weighted F1 improvements were 3.2%, 7.1% and 8.2% on MMT-09, DermNet and MMT-74.
  • In longitudinal tasks, change detection AUROC improved from 0.596 to 0.706 on SDDI1 and from 0.683 to 0.767 on SDDI2; for malignant lesions, PanDerm reached AUROC 0.840, surpassing the next-best model by 15.0%. Metastasis prediction reached AUROC 0.964, and high-risk patients had shorter recurrence-free intervals (HR 5.63; 95% CI 2.87–11.02, P < 0.001), with time-dependent AUCs of 0.950, 0.931 and 0.909 at 3, 5 and 7 years.
  • TBP tasks: photodamage weighted F1 0.896, nevus counting AUROC 0.983, risk stratification AUROC 0.705 and BACC 0.657. Malignant lesion screening sensitivity was 0.893, detecting malignant lesions in 79 of 80 patients while reducing unnecessary examinations by 60.8% versus melanographers (3,498 versus 8,913 lesions). Reader studies showed PanDerm outperformed average human reviewers by 10.2% in early melanoma detection, identified 77.5% (69/89) of melanomas at the first imaging time point versus 32.6% (29) for humans, improved skin cancer diagnostic accuracy from 0.69 to 0.80, and improved generalists’ top-3 accuracy by 16.5% across 128 skin conditions.

Methods

  • Design: PanDerm is a self-supervised multimodal foundation model with a ViT-Large visual encoder, a mask regressor and a CLIP-Large teacher model. Pretraining used masked latent modeling and CLIP feature alignment, with 50% mask ratio, 224 × 224-pixel inputs, 500 epochs, batch size 480 per GPU (effective 1,920), and 4 × 80-GB NVIDIA H100 GPUs for approximately 5 days and 7 hours.
  • Data and evaluation: Pretraining data came from 11 sources across 4 modalities. Evaluation covered 28 benchmarks, including 10 public datasets from 4 imaging modalities and 7 international sites, plus internal datasets such as MMT-09, MMT-74, SD-128, SDDI1, SDDI2, ComBineMel and TBP cohorts. Three reader studies assessed early melanoma detection, human–AI collaboration for skin cancer diagnosis, and human–AI collaboration for 128 skin conditions.
  • Analysis: Main metrics included AUROC, weighted F1, Dice similarity coefficient, Jaccard index, sensitivity, top-1/top-3 accuracy and diagnostic confidence. Statistical approaches included k-fold cross-validation, nonparametric bootstrapping with 1,000 replicates, two-sided t-tests, permutation tests, Kaplan–Meier analysis and Cox proportional hazards regression.

Limitations

  • The paper states that validation covered approximately 200 skin conditions, only a fraction of over 1,000 known dermatological diagnoses and smaller than some prior work (for example, 445 conditions), with limited coverage of rare genetic disorders, complex systemic diseases and clinical variants.
  • The paper states that robustness and fairness evaluations mainly reflect overall accuracy rather than disease-specific analysis, have varying disease coverage across anatomical locations, and focus primarily on single imaging modalities; comprehensive bias assessment requires metrics beyond overall accuracy, and equitable stand-alone performance may not translate to unbiased human–AI collaboration.
  • Evident from the text: the evaluations are retrospective benchmark and reader studies, and the paper does not report prospective clinical deployment or patient-outcome trials.

  • Recent high-impact studies demonstrate the clinical utility of multimodal large language models in dermatology, combining visual and textual reasoning to improve diagnostic accuracy.

    “Recent high-impact studies, such as (5), demonstrate the clinical utility of multimodal large language models in dermatology, combining visual and textual reasoning to improve diagnostic accuracy.”

    From Revolutionizing dermatopathology using AI in skin diagnostics: scoping review (2026) · cites this paper as [5]

    The Abstract reports that PanDerm improved clinicians’ diagnostic accuracy, supporting the clinical-utility part of the claim. But the Main and Methods describe a multimodal vision foundation model trained on several types of skin images, not a multimodal large language model combining visual and textual reasoning. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Most public dermatology datasets are small, unimodal, and paired with heterogeneous labels and metadata, restricting effective model development.

    “Most publicly available dermatology datasets are unimodal, limited in size, and composed mainly of dermoscopic or clinical images 3,4,13,20,21,42-47 , often photographs, paired with heterogeneous metadata or categorical labels that are lacking expressive textual information 48 .”

    From Synthesized clinical notes enable training robust multimodal AI models from unimodal dermatology datasets (2026) · cites this paper as [4]

    The Main section (page not available) says dermatology-specific approaches using public datasets are often limited by dataset size or diversity, and that specialty-specific models typically focus on single imaging modalities. The Methods section describes image datasets with categorical diagnoses, but our copy does not establish that most public datasets have heterogeneous metadata or lack expressive textual information. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • This supports the findings of (5), especially in emphasizing the practical relevance and significance of multimodal inputs in enhancing diagnostic precision and clinical generalizability.

    “This supports the findings of (5), especially in emphasizing the practical relevance and significance of multimodal inputs in enhancing diagnostic precision and clinical generalizability.”
  • The development of foundation models is reshaping dermatology, with multiple models such as SkinGPT4, PanDerm, and Derm1M.

    “The development of foundation models is also reshaping the dermatology domain, with multiple models such as SkinGPT4 2 , PanDerm 4 , Derm1M 3 , paving the way for an increased use of such models in the domain.”
  • Transformer-based methods support clinical text processing, whole-slide and radiologic image interpretation, and genomic sequence modeling in oncology.

    “In oncology, transformer-based methods support clinical text processing, whole-slide and radiologic image interpretation (vision transformers), and genomic sequence modeling [24,25,26,27].”

Each contradiction between two passages listed here was confirmed by an independent check.

  • Patient-level malignant detection exceeds the number of malignant test lesions

    Major

    The paper says malignant lesions were detected in 79 of 80 patients, but specifies that those 80 test patients had only 28 malignant lesions. At most 28 patients could each have had a malignant lesion detected.

  • Generalist reader-group composition differs between Results and Methods

    Minor

    The Results count eight GPs and two readers in the nurse and assistant roles; the Methods count seven GPs and three other healthcare professionals.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-07.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-07.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
