[Clinical and pathological differential diagnosis of condyloma and pseudo-condyloma of vulva].

Three hundred and twenty-one biopsies from vulva, comprising 18 cases of condyloma acuminata (5.6%), 202 cases of pseudo-condyloma (62.9%), and 101 cases of non-specific vulvitis (31.5%), are reported. Clinically, most condylomata acuminata appeared as multiple soft papillary and verrucous lesions with local itchiness. The majority of patients with pseudo-condyloma were symptomless but with harbor roe-like warty papulae distributed symmetrically on both labia minora. Histologically, 18 cases of condyloma acuminata presented papillomatosis, parakeratosis, dyskeratosis, acanthosis, basal cell atypical hyperplasia and distinct koilocytosis. Pseudo-condylomata showed papillomatous growth but without atypical hyperplasia of basal cells and distinct koilocytosis.
