Patients have well-delineated, livedoid, violaceous plaques with ulceration. As the process persists, the epidermis reacts to the inflammatory agent by undergoing increased proliferation, resulting in the histologic changes associated with subacute and chronic spongiotic dermatitis. The primary differential diagnosis for acute GVHD is with a drug eruption.

Toxic epidermal necrolysis. J Am Acad Dermatol. Billings SD, Cotton J. Briefly, grade I acute GVHD is characterized by basal vacuolization and a mild superficial perivascular infiltrate of lymphocytes. Sometimes there is a subcorneal pustule. It may be seen in between 20 and 80% of patients with allogeneic stem cell transplantation [19]. While most pathologists, feel relatively comfortable with cutaneous neoplasms, inflammatory dermatoses are a frequent source of diagnostic anxiety. J Eur Acad Dermatol Venereol. 2003;25:4635.

Histologic findings associated with early lichen sclerosus include a lichenoid lymphocytic infiltrate, exocytosis of lymphocytes, dyskeratotic cells at multiple levels of the epidermis, basement membrane thickening, submucosal or superficial dermal fibrosis, perivascular hyalinization, and irregular to psoriasiform epidermal hyperplasia (Fig. In cutaneous lichen simplex chronicus, there is often vertically oriented, thickened collagen bundles in the superficial dermis (Fig. The presence of neutrophils in the stratum corneum without serum should prompt consideration of psoriasis. 2018;93(Sep):120212. 2015;10:52930.
