title: Inverted papilloma of bladder.
abstract: The fifth reported case of a rare variant of transitional papillary tumor of the bladder termed inverted papilloma is reported with a brief review of the literature.  This tumor is likely to be confused with invasive malignant papillary carcinoma although it has adistinct histologic pattern, and it is for this reason that attention is drawn to the entity.
