Garrido-Abad, PabloGarcía Martín, LuisVillar Zarra, KarenDíaz Menéndez, ArielFernández Arjona, Manuel2020-10-082020-10-0820191677-6119http://hdl.handle.net/10641/1997Bladder cancer is a common cancer that may present as superfi cial, invasive, or metastatic disease. Non‐muscle‐invasive bladder cancer (NMIBC) represents the majority of bladder cancer diagnoses, but represents a spectrum of disease with a variable clinical course, notably for signifi cant risk of recurrence and potential for progression. NMIBC metastasis to distant organs without local invasion or regional metastasis is a very rare occurrence, so there are limited case reports about early metastasis in the literature.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Urinary Bladder NeoplasmsNeoplasm MetastasisLower Urinary Tract Symptomsjournal articleopen access10.1590/S1677-5538.IBJU.2018.0863
