Squamous papillae of the vulva represent a controversial lesion. Forty-six women with histologically confirmed vulvar squamous papillae and koilocytosis were studied at Chang Gung Memorial Hospital. Vulvar washings were analyzed by the filter in-situ technique using biotin-labeled probes for typing human papillomavirus DNA. Forty of 46 women (87%) were symptomatic. Human papillomavirus (HPV) DNA was detected in 76% (35 of 46) of women, including type 6/11 in 21.7%, type 16/18/31/33 in 45.6%, and both types in 8.6%. Furthermore, intraepithelial neoplasia was found in the epithelium of squamous papillae in two women. This study suggests the potential value of histologic examination and HPV DNA typing in separating anatomic variation from pathologic squamous papillae. We suggest that those squamous papillae with histologic evidence of koilocytosis be designated as squamous papillomatosis.
