This photomicrograph depicts a Tzanck stained penile lesion specimen, which proved to be positive for the presence of herpes simplex virus (HSV). A Tzanck test involves extracting a sample of tissue from the floor of a bullous, i.e., maculopapular lesion, processing the sample, and examining it in order to see if there are any abnormal cell types present such as multinucleated giant cells, as were present in this case, of herpes progenitalis, also known as herpes genitalis.
