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.

Poliosis overlying a nevus with blue nevus features

Dermatology Online Journal, 2008
Poliosis is a localized patch of gray or white hair. Because it can be seen with a variety of disorders and drugs, a full history and exam is indicated. Additionally, it can be associated with underlying benign and malignant tumors, necessitating histological identification. We review the lesions that are reported with poliosis.

Small lesion, big challenge? Diagnosis of small diameter melanocytic lesions by dermatologists using AI support

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Dermoscopy enhances melanoma detection, but small‐diameter melanomas (SDMs) remain diagnostically challenging. Convolutional neural networks (CNNs) may detect subtle patterns beyond human perception. This study evaluates how lesion diameter influences the diagnostic accuracy of dermatologists, with and without CNN support.

Surgical removal of a perirectal melanoma through sphincterotomy and rectal wall resection in a horse

Equine Veterinary Education, EarlyView.
Summary Melanomas are among the most frequent neoplasms in grey horses. Deep perirectal melanomas, however, are uncommon and challenging to excise due to their proximity to the peritoneal reflection. This report describes the successful standing removal of a large (16 × 8 × 6 cm) perirectal melanoma firmly adherent to the dorsal rectal wall in a 19 ...

Reflectance Confocal Microscopy Versus Line‐Field Confocal Optical Coherence Tomography in Facial and Scalp Lesions Suspicious for Basal Cell Carcinoma: A Histopathology‐Referenced Multi‐Reader Study

International Journal of Dermatology, EarlyView.
Comparison of reflectance confocal microscopy (RCM) and line‐field confocal optical coherence tomography (LC‐OCT) for the diagnosis of facial and scalp basal cell carcinoma. RCM showed higher sensitivity, specificity, accuracy, and inter‐reader agreement, particularly in dermoscopically equivocal lesions.

Prospective subtyping of head and neck basal cell carcinoma by dermoscopy and handheld RCM

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Handheld reflectance confocal microscopy, alone or with dermoscopy, increases specificity, maintains high sensitivity and improves diagnostic confidence for head and neck basal cell carcinoma. It may offer a non‐invasive alternative to confirmatory biopsies when planning micrographically controlled surgery in clinically high‐risk cases.
