Dermoscopic Examination of Nail Pigmentation

Abstract: Background: Diagnosis of longitudinal melanonychia is usually difficult, and neither a single clinical criterion nor a combination of symptoms currently can be used to clearly distinguish malignant from benign bandlike pigmented nail lesions. Biopsy is painful and often leaves definitive dystrophic scars.Objectives: To describe and evaluate dermoscopic patterns associated with longitudinal nail pigmentation.Patients and Methods: A total of 148 unselected consecutive cases of longitudinal melanonychia were incl… Show more

“…From the findings of Ronger et al, 18 the practical value of dermoscopic examination of nail pigmentation is evident, especially for subungual hemorrhage, which is in our experience the most common pigmentation of the nail and worrisome for patients who are not able to remember any trauma. The presence of red to bluishblack blood spots on dermoscopy allows the clinician to make the correct diagnosis with confidence and to reassure the patient immediately.…”
