Abstract		CD56+ rich inflammatory infiltrates have been described in several cutaneous inflammatory conditions. However, CD56+ cells rarely account for more than 10% of the cells in such infiltrates. In certain conditions, such as insect bites or infection with herpes virus, CD56+ cells can be up to 43% of the cells in the infiltrate. This contrasts with what is observed in natural killer (NK)-cell lymphomas, which show a diffuse, atypical infiltrate in which most of the cells are CD56+. In this report, we describe a lymphocytic infiltrate in an ulcerated lesion on the lip of a 53-year-old man resulting from infection with herpes simplex virus type 2. CD56+ cells represented 80 to 90% of the infiltrate, showing atypical morphologic features, and clusters of CD56 positive cells were also observed.
