TLDR
The patterns described present high sensitivity and specificity for intraoperative differential diagnosis of pigmented nail lesions and can not routinely be performed in all cases of melanonychia.Abstract:
Background The dermatoscopic examination of the nail plate has been recently introduced for the evaluation of pigmented nail lesions. There is, however, no evidence that this technique improves diagnostic accuracy of in situ melanoma. Objective To establish and validate patterns for intraoperative dermatoscopy of the nail matrix. Methods Intraoperative nail matrix dermatoscopy was performed in 100 consecutive bands of longitudinal melanonychia that were excised and submitted to histopathologic examination. Results We identified 4 dermatoscopic patterns: regular gray pattern (hypermelanosis), regular brown pattern (benign melanocytic hyperplasia), regular brown pattern with globules or blotch (melanocytic nevi), and irregular pattern (melanoma). Limitations Nail matrix dermatoscopy is an invasive procedure that can not routinely be performed in all cases of melanonychia. Conclusion The patterns described present high sensitivity and specificity for intraoperative differential diagnosis of pigmented nail lesions.read more

TL;DR: The accuracy of dermoscopy for the detection of invasive melanoma or atypical intraepidermal melanocytic variants was reported in 86 datasets; 26 for evaluations conducted in person (dermoscopy added to visual inspection), and 60 for image-based evaluations (diagnosis based on interpretation of Dermoscopic images).

Dermoscopy of non-skin cancer nail disorders.
TL;DR: Except for some diseases in which the technique really adds a lot to clinical examination, in most of the cases, nail dermoscopy only permits a better visualization of symptoms already evident to the naked eye.

Tips for Diagnosis and Treatment of Nail Pigmentation with Practical Algorithm
TL;DR: Nail melanoma is a much less frequent cause of brown-black nail color than other melanocytic and nonmelanocytic pigmentations, which include subungual hematoma, exogenous pigmentation, and melanonychia due to benign conditions.

TL;DR: The virtual Consensus Net Meeting on Dermoscopy represents a valid tool for better standardization of the dermoscopic terminology and, moreover, opens up a new territory for diagnosing and managing pigmented skin lesions.

TL;DR: Dermoscopic examination of the nail plate in cases of longitudinal melanonychia provides useful information that could help clinicians to more accurately decide if a nail apparatus biopsy should be performed; however, histopathologic diagnosis remains the gold standard in doubtful cases.

TL;DR: In this paper, a new algorithm for non-invasive diagnosis of nail pigmentation using dermoscopy has been proposed to reduce the number of unnecessary surgeries and to choose the most adequate biopsy technique.
