[Bladder inverted papilloma. Can it be considered as a neoplasm with low degree of malignancy?].
We report a case of inverted papilloma of the bladder. The clinical features, diagnosis and treatment of this tumor type are discussed. We underscore the histology and histogenesis of the two types: trabecular inverted papilloma and glandular inverted papilloma. A review of the literature has shown that inverted papillomas do not show clinical or histological features of malignancy most of the time. The cases with synchronous or metachronous association with transitional cell carcinoma, recurrence or histologic signs of malignant transformation of a lesion may be considered to have a neoplasm of low grade malignancy and these patients must be followed closely.
