abstract

  • Small-cell undifferentiated carcinoma (SCUC) has been increasingly recognized in the urinary tract.1,2,3 Up to 66% of SCUCs in this location are associated with a minor component of a more differentiated carcinoma that most frequently represents transi tional-cell carcinoma (TCC), but adenocarcinoma, squamous-cell carcinoma, spindle- cell carcinoma, and carcinoid carcinoma have all been described. We report a case of low-grade TCC of the urinary tract metastasizing to a distant location and therein dedifferentiating into an SCUC and discuss the clinical and biologic implication of the process of dedifferentiation.
