title: [A rare variety of urothelial carcinoma. Apropos of 2 cases].
abstract: We report two cases of grade 1 papillary transitional cell carcinoma which have a distinct pathological. The tumor was infiltrating the lamina propria in the first case (pT1) and the superficial muscle in the second case (pT2). These tumors were composed by nests and tubules with few cytological atypias, making the diagnosis of cancer difficult. The prognosis of these tumors is not well defined.
