Sexton Mack M.D.The American Journal of Dermatopathology: June 1991 ORIGINAL ARTICLE: PDF Only Buy Abstract Two cases of cutaneous herpesvirus infection are described that clinically masqueraded as pseudolymphoma. Light microscopy demonstrated typical viral changes involving pilosebaceous complexes with sparing of the surface epithelium. Dermal changes consisted of a dense perivascular and perifollicular inflammatory infiltrate. Multinucleated lymphoid cells were found in the dermis in one case and viral inclusions in fibroblasts were present in the other case. Immunoperoxidase stains with antisera to herpes simplex virus types I and II were positive in one case and negative in the other case. Ultrastructural examination demonstrated viral particles consistent with herpesvirus in both cases. Recognition of typical histologic features of herpesvirus folliculitis will lead to an accurate diagnosis in these types of clinically unsuspected cases. © Lippincott-Raven Publishers.
