A case of inverted papilloma with subsequent heterotopical recurrence of inverted type transitional cell carcinoma is reported. A 24-year-old man had a medical examination of our hospital with chief complaint of asymptomatic macroscopic hematuria on October 23, 1982. Cystoscopy revealed a smooth surfaced and finger-tip sized tumor at the bladder neck. Because of the large bulk and the location ...

The objective of this paper was to study the extraction methods of tannin constituents from Semen Cuscutae and their anti-papilloma effects. Single factor test and orthogonal design methods were used to determine the optimal extraction method; the mouse skin papilloma model induced by DMBA/croton oil was established, which was a classic two-stage carcinogenesis model being used to observe and e...

Inverted papilloma of the bladder is thought to be benign, but some urothelial carcinomas show a prominent inverted growth pattern which may pose a diagnostic dilemma. A recent meta-analysis of 322 cases reported with respect to inverted papilloma of the lower urinary tract identified a recurrence rate of 3.85%. Moreover, 1.55%, 5.90% and 1.54% were associated with previous, simultaneous and su...

Mixed squamous cell and glandular papilloma of the lung is an extremely rare benign epithelial tumor showing a mixture of squamous and glandular epithelium. Here, we report a case of mixed squamous cell and glandular papilloma that presented as a solitary nodule in the left lower lobe of a 64-year-old woman. Chest computed tomography demonstrated a lobulated mass in the basal segment of the lef...

Surgery offers the optimum modality of treatment for inverted papilloma although a considerable range of operative approaches have been described. The results are presented in a cohort of 37 cases treated by both endoscopic and combined endoscopic and external approaches with a recurrence rate of eight and 21 per cent respectively. This series is compared with those in the literature and demons...

Twelve neonate calves were repeatedly challenged with bovine papilloma virus. All calves were initially susceptible to bovine papilloma virus and complete resistance to challenge occurred after the onset of fibroma regression. Fibroma regression was not correlated with serum antibody titers to bovine papilloma virus as measured by an immunodiffusion assay. Fibroma regression occurred prior to t...

=Abstract=ln situ hybridization using digoxigenin labeled HPV(human papillornaviruses) probes was tried in order to detect the presence of HPV DNA in 27 cases of single and multiple laryngeal papilloma. There were HPV6/11 DNA signals in 17 out of 22 cases of multiple laryngeal papilloma and in all five cases of single laryngeal papilloma. The specific signals were seen focally in the nuclei of ...

Human papilloma virus was detected by in situ hybridisation in routinely processed paraffin wax sections using a synthetically produced oligonucleotide probe, end-labelled with biotin, and amplified with anti-biotin-immunogold silver staining (anti-biotin-IGSS). This system proved more sensitive than amplification with streptavidin-biotinylated alkaline phosphatase for detecting human papilloma...

Inverted urothelial papilloma is a rare benign tumour and represents one of the urothelial lesions with inverted morphology. Accurate diagnosis and differentiation from other inverted lesions is important because its proper clinical management and expected clinical outcomes are distinctly different. Here we describe a case of a large inverted urothelial papilloma of the prostatic urethra and a ...

Even though endoscopic removal of inverted papillomas has gained popularity, many studies advocate supplementary external approaches. The impact of including the current surgical staging system into the pre-operative clinical and radiological assessment has not been systematically evaluated. We present our experience with total endoscopic management of inverted papillomas and compare the accura...
