## Abstract Cholesteatoma of the middle ear is a relatively common disorder, often with severe consequences. Histologically, the aggressively growing, boneβdestructing form shows papillary growth and koilocytosis, which are characteristic of papillomavirusβinduced lesions. A PCR (polymerase chain r

β¦ Synopsis
Solitary keratoacanthomas of 32 patients were screened for the presence of human papillomavirus (HPV) 25 DNA, which was originally isolated and molecularly cloned from warts of an epidermodysplasia verruciformis (Ev) patient. Biotinylated virus DNA was hybridized in situ to thin sections obtained from paraffin-embedded material. HPV DNA was detected in 12 of 32 tumors under stringent conditions, and in 2 additional tumors under relaxed conditions.

To detect the presence of human papillomavirus (HPV) DNA in penile cancers, 18 squamous-cell carcinomas were studied by Southern blot analysis. All specimens were from Brazilian patients ranging in age from 31 to 78 years. Of these, 7 harbored DNA sequence homology. Most positive specimens contained
Human papillomavirus (HPV) is associated with benign cutaneous or mucosal lesions and with malignant tumours, but none of the HPV types has so far been related to skin tags. Skin biopsy specimens from 49 Caucasian patients suffering from the presence of multiple soft fibromas were analysed by means
