Dysplastic nevus (atypical nevus).

Anais brasileiros de dermatologia, 2011
Atypical nevum (dysplastic) is considered an important factor associated with increased risk of developing cutaneous melanoma. It is believed that atypical nevi are precursor lesions of cutaneous melanoma. They may be present in patients with multiple melanocytic nevi (atypical nevus syndrome) or isolated and in small numbers in a non-familial context.

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.

Age‐related dermatoscopic features of excised melanomas versus nevi in 832 high risk patients

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Melanocytic nevi show distinct age‐related dermoscopic patterns. However, data on age‐related patterns of melanomas are lacking. This study aimed to identify age‐related static and dynamic dermoscopic patterns of melanomas. Patients and methods Explorative cross‐sectional cohort study between October 1996 and May 2012,

Spitzs Nevus Arising On a Nevus-Spilus

, 1994
The first case of a solitary dermal Spitz's nevus arising on a nevus spilus is described. This special variant of a combined Spitz's nevus may cause difficulties in differential diagnosis from malignant melanoma in association with a nevus ...

AI‐assisted diagnosis of nail unit melanoma and melanonychia using a clinical deep learning model

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Nail unit melanoma (NUM) is a rare but potentially fatal malignancy often misdiagnosed as melanonychia. Because biopsy may cause permanent nail dystrophy, accurate noninvasive diagnosis is essential. This study aimed to develop and validate an artificial intelligence model to distinguish NUM from benign melanonychia ...

A large-scale genome-wide association meta-analysis for nevus count provides direct insights into the genetics of melanoma

Nature Communications
A greater understanding of the biology of nevi will provide insights into the etiology of melanoma. Our large-scale meta-analysis of 14 nevus genome-wide association studies (GWAS) includes 85,965 individuals of European ancestry.

Patient with giant Becker’s nevus and epidermal nevus

, 2011
Becker’s nevus is a cutaneous hamartoma that may be present at birth, but more commonly is noticed during puberty. It classically manifests unilaterally on the shoulder and upper trunk as a tan to brown patch or thin plaque.

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.

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.

Halo nevus [PDF]

Halo nevi (leukoderma acquisitum centrifugum, Sutton's nevus, leukopigmentary nevus, perinevoid vitiligo or perinevoid leukoderma) are melanocytic nevi surrounded by a halo of hypopigmentation or depigmentation.
