[Renal pelvis mucinous carcinoma. Case report].
OBJECTIVE
There is some controversy in the terminology used for transitional cell tumors with mucinous differentiation.


METHODS
We report the case of a 50-year-old male with history of recurrent lithiasis whose radological tests discovered a heterogeneous renal pelvis lesion.


RESULTS
The histologic study of the lesions determined the diagnosis of transitional cell carcinoma of the renal pelvis with ample mucinous differentiation.


CONCLUSIONS
They are rare tumors in such location and the mucinous differentiation does not seem to influence prognosis.
