Lichen sclerosus et atrophicus and perianal carcinoma: a case report

“…The reported incidence of carcinoma developing varies in different series and with the length of the follow up of patients. The average from several series is 5-2",, (Nicolau & Balus, 1966;Perry & Homme, 1965;Suurmond, 1964). This probably will be an over-estimate of the true incidence as many people with mild LSA will not be seen by dermatologists.…”

“…The condition is uncommon with females predominating (Nicolau & Bolus, 1966). Nowadays most people regard it to be a separate entity.…”

Lichen Sclerosus et Atrophicus An Electron Microscopic Study

“…Lichen sclerosus et atrophicus is character'ized histologically by tbe presence of an amorphous and cellular band underneath the epidermis (Montgomery & Hill 1940, Hauser 1958, Steigleder & Raab 1961, Suurmond 1964, Montgomery 1967, Hadida et al, 1970, The electron tnicroscopic studies of the subepidermal homogeneous zone reveal the presence of immature collagen fibrils and of bundles of closely packed but thin fibers showing a regular periodicity (Forssmann et al 1964, Nicolau & Balus 1966, Hadida et al 1970, Klug & Sonnichsen 1972, Mann & Cowan 1973. The subepidermal basement membrane is often broadened, and according to Klug & Sonnichsen (1972) the basal epidermal cells may show dyskeratotic signs and acantholysis.…”
