Microbiological screening, including Grocott staining of the biopsy material for fungal hyphae was performed. Forty nine biopsies showed marked koilocytosis suggestive of human papilloma virus (HPV) infection, and of these, only three showed fungal hyphae. This study suggests that HPV may be associated with some cases of patchy balanoposthitis.
