s. Lichen planus classic type. Lichen planus with anular formations. The Lichen planus anularis can occur as a single focus, but also polytopic or within a generalized Lichen planus. Anular structures are formed by centrifugal growth of a single focus (cf. granuloma anular, anular sarcoidosis and others). Anular growth patterns are also frequently found in the lichen planus actinicus.
In this respect, it is not an entityic clinical picture but a special morphological phenomenon, whose ätopathogenetic significance has not yet been clarified.
