Purple penile papules.
Molluscum contagiosum may present in a variety of clinical and pathologic guises. We present the clinicopathologic features of an unusual case that initially was misinterpreted as bowenoid papulosis. The relevant histologic attributes of this case include the presence of a violaceous hyperplastic squamous epithelium adjacent to the infected keratinocytes. The presence of this violaceous cytoplasmic staining should prompt a search for molluscum in the appropriate clinical context.
