Dermoscopy Allows Better Management of Nail Pigmentation

Patterns of nail matrix and bed of longitudinal melanonychia by intraoperative dermatoscopy

“…11 Nail plate dermatoscopy has been proposed as a useful technique in the evaluation of nail pigmentation. 3,12,13 Its value in the differential diagnosis of nail melanoma has not been established. 6,14,15 Our results show that intraoperative dermatoscopy provides useful information for the differential diagnosis of LM.…”

Diagnosis and management of nail pigmentations

“…Recently, dermoscopy has been described to be useful for the evaluation and diagnosis of longitudinal melanonychia. 1,12 For the examination of the nail apparatus we recommend the use of a gel such as ultrasound gel as immersion medium 11 because its decreased viscosity permits it to stay on the nail plate and fill any concavities without rolling off. For the evaluation of the pigmentation and to appreciate the thin lines within the nail band, it is useful to vary the focus of the device during the examination.…”

“…Longitudinal melanonychia has been reported in Algorithm for dermoscopy diagnosis of nail pigmentation that is of melanocytic origin. 1,12 In the first step, pigmentation should be evaluated for its color. Grayish color is highly suggestive of focal melanocytic activation in the absence of any melanocytic hyperplasia.…”

Using Dermoscopic Criteria and Patient-Related Factors for the Management of Pigmented Melanocytic Nevi

“…65 Therefore, these nevi are referred to as nevi of special body sites and show a pseudonetwork pattern (face), 18,27 parallel furrow pattern (acral areas), [30][31][32][35][36][37]66 regular bandlike pattern (nails), 33,34,[67][68][69] and a globular mixed pattern (mucosa). [70][71][72][73] For mucosal nevi, no specific studies have been performed yet to our knowledge.…”
