D. Lichen Scrofulosorum
Ans:C. Lichen Nitidus
- It is a relatively rare, chronic skin eruption that is characterized clinically by asymptomatic, flat-topped, skin-colored micropapules .Lichen nitidus mainly affects children and young adults.
- The primary lesions consist of multiple 1- to 3-mm, sharply demarcated, round or polygonal, flat-topped, skin-colored shiny papules that often appear in groups.
- The Köbner phenomenon (or an isomorphic response) may be observed.This phenomenon causes the occasional linear pattern of the lesions associated with lichen nitidus.
- The most common sites of involvement are the trunk, flexor aspects of upper extremities, dorsal aspects of hands and genitalia.
- Infrequently, the lower extremities, palms, soles, face, nails, and mucous membranes may be affected.
- Nail changes include pitting, ridging, splitting, and linear striations.
- No therapeutic modality has been rigorously evaluated for the treatment of lichen nitidus because of the rarity, lack of significant symptomatology, and disappearance of this disease within one or several years.
- Topical and systemic steroids, topical tacrolimus, systemic cetirizine, levamisole, etretinate, acitretin, itraconazole, cyclosporine, psoralen plus UV-A light, and narrow-band UV-B light may be helpful.
