Hypertrophic lichen sclerosus. Figure 5 is more typical of LS, but the first pictures show psoriasiform hyperplasia and less defined papillary dermal sclerosis. The presence of necrotic keratinocytes above the dermal papillae (figure 1 and 2) are a good tip.

Lichen sclerosus et atrophicus (LS&A). Nice interface vacuolar dermatitis with attenuation of rete pegs, patchy lichenoid lymphocytic infiltrate, and glassy hyaline fibrosis in upper dermis. Foreskin (genital) location is classic.

Lichen sclerosus. It is said that the better term is just lichen sclerosus as atrophy is not always the case, and hypertrophic changes can be encountered.
