Background Dermoscopy has furthered advances in the differential diagnosis of longitudinal melanonychia; however, fewer details observed in the nail, as compared to skin lesions, make interpretation difficult. Methods Ten cases of longitudinal melancholia, from several etiologies, were submitted to direct dermoscopic examination of the nail bed and matrix. Results We observed the presence of globules, streaks, and pigment network in the nail bed and matrix, which are dermoscopic features not seen in the nail plate. Conclusions This procedure enables visualization of dermascopic features not seen in the nail plate, making the diagnosis of melanocytic lesions easier.
