Mixed squamous and glandular papilloma of the lung is uncommon. Current literature demonstrates that there are less than 20 cases documented worldwide, though likely underreported. We present a case of a 58 y.o. female with history of COPD who was found to have mixed squamous and glandular papilloma, confirmed by histology. This case highlights an unusual etiology of endobronchial lesion that c...

Solitary endobronchial papillomas (SEPs) are rare benign tumors of the lung, seldom transform to malignancy. This tumor had been reported occasionally manifest like carcinomas histologically. Herein we report 2 cases of SEPs; one is a squamous cell papilloma providing a false impression of interstitial micro-invasion. The other is a mixed squamous cell and glandular papilloma with massive lipid...

Intracranial Fibroblastic neoplasms developed in 16 of 19 hamsters inoculated intracerebrally with bovine papilloma virus. The tumors presumably arose in the meninges and infiltrated the adjacent brain along the vascular channels. Tumor nodules that developed in the subcutis of the extremities, ears, and body were probably due to viremia following intracerebral inoculation. Fibroblasts of the c...

We report a new case of inverted papilloma of the ureter, with an uncommon clinic manifestation as a obstructive uropathy. In spite of the bening nature the inverted papilloma of the urinary tract, it can be multifocal and relapsing and it may be associated with low rate urothelial carcinomas. A precise pre-operative diagnosis is necessary for a conservative or endourologic treatment. The follo...

A case of Aicardi syndrome associated with a choroid plexus papilloma of the third and both lateral ventricles in a 15 months old baby girl is repported. The tumor was completely removed via three craniotomies. Reports of the literature with the association of choroid plexus papilloma and Aicardi syndrome are rare. We suggest that children diagnosed with Aicardi syndrome should routinely underg...

An 82-year-old male who presented with the chief complaint of gross hematuria and a history of prostate cancer treated with brachytherapy 6 years previously is described. Cystoscopy revealed multiple bladder tumors on the right posterior wall. A transurethral resection of the bladder tumor was performed and a pathological diagnosis of the inverted papilloma was made. To the best of our knowledg...

BACKGROUND Our aim was to review our management of inverted papilloma (IP), perform a recurrence analysis, and review the literature. METHODS A retrospective analysis of 247 patients treated for an IP. Patients were grouped according to surgical approach, tumor presentation (primary, residual and recurrence) and Krouse-stage. RESULTS Recurrence was observed in 20.3%, 28.6% and 35.1% (p = 0....
