We describe a case of benign inverted papilloma with intracranial extension treated with endoscopic resection combined with craniotomy. Intracranial involvement of inverted papilloma, in the absence of malignancy, is uncommon. We present an analysis of the literature identifying the characteristics and outcomes of benign intracranial inverted papilloma. PubMed database was searched using keywor...

BACKGROUND Primary inverted papilloma of the sphenoid sinus is rare. The tumor is considered locally aggressive. In selected cases inverted papilloma can be associated with squamous cell carcinoma. Radiologic imaging is a key to an accurate diagnosis. AIM We analyzed patient with inverted papilloma in sphenoid sinus which was removed with endoscopic surgery. MATERIAL AND METHODS We discuss ...

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...

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 ...

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 ...

Inverted papilloma of the urinary tract is a rare benign lesion. We report, to our knowledge, the first case of inverted papilloma of the prostatic urethra arising in a juvenile. Our patient was referred for evaluation of painless, gross hematuria and voiding difficulty. Transrectal sonography demonstrated a 1.4 cm papillary lesion on the medial aspect of the prostatic urethra. Cystoscopy showe...

Inverted papilloma is an uncommon primary nasal tumor. Despite its benign nature, this tumor represents three typical characteristics: a high propensity of recurrence, local aggressiveness and association with malignancy. Inverted papilloma can reduce the patient's quality of life due to compromised nasal function, extension to the orbit and brain. The authors reported the unusual case of a 72-...

To investigate the histopathological characteristics of inverted papillomas of the urinary bladder, including the possibility of malignant transformation, we studied the indicators of cellular proliferation activity in 7 inverted papillomas of the bladder including two cases of malignant inverted papilloma of the bladder. PCNA expression rates in two cases of malignant inverted papilloma were h...
