Department of Dermatology, The Second Affiliated Hospital of Kunming Medical University, Kunming, Yunnan, China.
Background: There are no standards for evaluating skin photoaging. Dermoscopy is a non-invasive detection method that might be useful for evaluating photoaging.
Objective: To assess the correlation between the dermoscopic evaluation of photoaging and clinical and pathological evaluations.

Background: The removal of hair and ruler marks is critical in handcrafted image analysis of dermoscopic skin lesions. No other dermoscopic artifacts cause more problems in segmentation and structure detection.
Purpose: The aim of the work is to detect both white and black hair, artifacts and finally inpaint correctly the image.

Hair and ruler mark structures in dermoscopic images are an obstacle preventing accurate image segmentation and detection of critical network features. Recognition and removal of hairs from images can be challenging, especially for hairs that are thin, overlapping, faded, or of similar color as skin or overlaid on a textured lesion. This paper proposes a novel deep learning (DL) technique to detect hair and ruler marks in skin lesion images.

Background: Delays in sentinel lymph node (SLN) biopsy may affect the positivity of non-SLNs. For these reasons, effort is being directed at obtaining reliable information regarding SLN positivity prior to surgical excision. However, the existing tools, , dermoscopy, do not recognize statistically significant predictive criteria for SLN positivity in melanomas.
