human papilloma virus causes benign and malignant abnormalities in different part of the body. the link between high risk types of hpv and some anogenital and aerodigestive tract cancer is well established. oral hpv infection plays a role in developing oropharyngeal squamous cell carcinoma. we studied the prevalence of oral hpv in healthy individuals and its relative risk factors.saliva samples...

purpose: to explore any association between human papilloma virus (hpv) infection and ocular surface squamous neoplasia. methods: forty pathological specimens including 20 cases of conjunctival intra-epithelial neoplasia grade i (cin i) and 20 cases of cin iii and invasive squamous cell carcinoma (scc) together with 20 pterygium samples (controls) were analyzed by polymerase chain reaction (pcr...

The differential diagnosis of a large breast mass in a post-menopausal woman can include both benign and malignant etiologies. Although rare, diagnosis of giant intraductal papilloma must be considered in the differential. Furthermore, although benign, papillomas presenting as a large breast mass affecting the skin require extensive breast surgical treatment.

A case of laryngeal squamous papilloma in the early stages of development showed histological features suggestive of virus infection. Five years later positive evidence of HPV-6 infection was obtained at a time when the lesion had developed into a squamous cell carcinoma. It is concluded that this case represents a complete example of the virus to papilloma to carcinoma sequence, and as far as ...

Four cases of choroid plexus papilloma extending through the foramen of Monro are presented. All four patients were evaluated by contrast-enhanced CT and two of these were also evaluated by neurosonography. No other intraventricular tumor commonly extends through a ventricular outlet. The radiographic demonstration of this extension of an intraventricular mass through the foramen of Monro, cere...

BACKGROUND Uroplakins are differentiation-related membrane proteins of urothelium. We compared uroplakin expression and ultrastructural localization in human normal urothelium, papilloma and papillary carcinoma. Because of high recurrence rate of these tumours, treated by transurethral resection, we investigated urothelial tumour, resection border and uninvolved urothelium. PATIENTS AND METHO...

Purpose The aim of this article is to report a case of lacrimal caruncle nevus with papilloma. Methods This is a case report of a 39-year-old female with a progressively enlarging pigmented lesion on the left lacrimal caruncle. She had been aware of a raised whitish wart on the top of this pigmented lesion for several months before her initial visit. Slit lamp examination revealed a papilloma...

1. The potentialities that viruses have for the superinfection of virus tumors have not been recognized nor has the fact that a single cell can harbor more than one virus. 2. Rabbit papillomas, induced by the papilloma virus (Shope), were superinfected by B virus, myxoma virus, vaccinia virus, and probably, virus III. Similar attempts at superinfection by herpes virus were without success. The ...

Induction of cutaneous squamous cell carcinoma (SCC) in mice, by topical chemical [9,10-dimethylbenzanthracene (DMBA) and phorbol 12myristate 13-acetate (PMA)] application, is a multistep process involving papilloma formation and progression to carcinoma. We have generated a transgenic (Tg) mouse [keratin-14 (K14)-survivin] with skin expression of survivin, an inhibitor of apoptosis expressed i...

Papillomas induced by the cottontail rabbit papillomavirus (CRPV) progress at a high frequency to carcinomas. In this regard, CRPV and its tumors can serve as an animal model for highly oncogenic human papillomaviruses. We have previously shown that immunization with major structural protein L1 elicits neutralizing antibodies and protects rabbits from papilloma development (Y.-L. Lin, L.A. Bore...
