In 3 cases of lymphomatoid papulosis with few ulceronecrotic lesions and 5 with the classic features of pytiriasis lichenoides acuta with necrotic lesions, a considerable part of the cellular component of the infiltrate of the lesions showed the morphologic and cytochemical characteristics of the cells described as immunoblasts. The authors consider that the lymphomatoid papulosis could represent an immunoblastic response to an unknown antigen.
