Background: Lichenoid dermatitis is a very common dermatological condition and defined by features of basal cell damage dense band-like infiltration at the dermo-epidermal junction. There wide range lesions included under this prototype lesion Lichen Planus.

Pseudonests or pseudomelanocytic nests represent aggregates of cells and cell fragments, including keratinocytes, macrophages, lymphocytes, and occasional melanocytes. Pseudomelanocytic nests in the setting of lichenoid inflammation can mimic atypical melanocytic proliferations. Several reports documented nonspecific staining of pseudonests with melanoma antigen recognized by T cells-1/Melan-A,...
