Dermoscopy of lichen nitidus: a study of 20 cases

Lichen nitidus (LN) is a chronic inflammatory lichenoid dermatosis, commonly seen in childhood or early adulthood. In this case series, we studied the various dermoscopic features of LN and correlate them with clinical variants, duration disease histopathology. A total 20 patients were studied. The mean age was 25.7 years 45% 55% male female, respectively. median 6 months. findings on non-polarizing mode were-shiny elevated surface absence skin markings (100%), scaling (70%), radial ridges (50%) central depression (35%). Findings polarizing were-hypopigmentation brown shadow linear vessels (65%), accentuation surrounding reticulate pigment network diffuse erythema (45%). Newer grey-brown structureless areas (30%), speckled (40%), curvilinear (50%), branching/serpentine (20%), (10%), white dots streaks (30%) ring-in-ring appearance (5%). presents fairly distinctive dermoscopy can be non-invasive, painless aid differentiating it from close differentials avoid need for biopsy, especially children.
