Multiclass convolutional neural network vs. 96 dermatologists in skin lesion diagnosis, an international study

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Artificial intelligence was shown to improve diagnostic accuracy for skin cancer detection. While most clinically approved models provide binary “benign/malignant” classifications, multiclass predictions may offer greater clinical utility.

Robustness of a neural network approved for skin cancer diagnosis against variations in sequential images

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background: Convolutional neural networks (CNN) for skin cancer classification have shown results comparable to dermatologists but are vulnerable to minor image transformations. We investigated the robustness of a MDR class‐IIa certified CNN when classifying sequential images of identical lesions.

Aneurysmal Dermatofibroma: Uncommon Presentation of Common Disease

Nepal Journal of Dermatology, Venereology & Leprology
Aneurysmal dermatofibroma is an uncommon, benign variant of dermatofibroma due to the slow extravasation of blood. Clinically, it is difficult to differentiate from other vascular occurring lesions like verrucous hemangioma and malignancies like ...

Cutaneous Leiomyosarcoma of the Skin: An Updated Review of Epidemiology, Pathogenesis, and Management

International Journal of Dermatology, EarlyView.
This review provides an update on the epidemiology, pathogenesis, and clinical/histologic features of cutaneous leiomyosarcoma. Prognostic factors (e.g., depth of tumor involvement, grade, etc.) that can facilitate risk stratification are also discussed, as are treatment approaches for this rare malignancy.

Multiple eruptive dermatofibromas [PDF]

Dermatology Online Journal, 2015
We report a 34 year-old woman with psoriasis, systemic lupus erythematosus (SLE), and recent anti-TNFa therapy, who presented with multiple, eruptive dermatofibromas (MEDF). Although the pathogenesis of MEDF remains unknown, there is substantial evidence that this phenomenon represents an aberrant immune response.

Fat necrosis with an associated lymphocytic infiltrate represents a histopathologic clue that distinguishes cellular dermatofibroma from dermatofibrosarcoma protuberans

Journal of cutaneous pathology, 2020
Cellular dermatofibromas (CDFs) and dermatofibrosarcoma protuberans (DFSP) can be challenging to differentiate from one another. Morphologically, both entities commonly extend into the subcutis, exhibit high cellularity with limited cytologic atypia and ...

Gastric Metastasis of Uterine Leiomyosarcoma Detected During Surveillance Endoscopy and Resected by Endoscopic Submucosal Dissection After Multiple Metachronous Metastases: A Case Report

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Uterine leiomyosarcoma (uLMS) is a rare, aggressive uterine malignancy that usually metastasizes hematogenously, whereas gastrointestinal involvement is uncommon. A 69‐year‐old woman with uLMS treated by hysterectomy and adjuvant chemotherapy developed metachronous lung, sigmoid colon, gallbladder, and abdominal wall metastases.

Explainable Deep Learning for Imaging‐Based Skin Lesion Diagnosis: A Systematic Literature Review

Concurrency and Computation: Practice and Experience, Volume 38, Issue 16, August 2026.
ABSTRACT In the latest years, the use of Deep Learning (DL) in imaging‐based skin lesion diagnosis has become increasingly prevalent. The deep models have revolutionized the computer‐aided diagnosis systems in terms of performance. However, DL models are often criticized as black boxes due to their complex and opaque internal design of numerous ...

Congenital Atrophic Dermatofibrosarcoma Protuberans: A Case Report and Narrative Review of the Literature

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Dermatofibrosarcoma protuberans is a rare dermal and subcutaneous soft‐tissue tumor, uncommon in children, characterized by CD34 positivity and COL1A1‐PDGFB fusion. Prognosis is generally good, but local recurrence risk is high, so complete excision with clear margins and six‐monthly follow‐up for three years after surgery is recommended in ...
