[New location of aggressive angiomyxoma: the bladder].

Presentation of one case of aggressive angiomyxoma with vesical location in a 31-year-old female patient who underwent partial surgery, and who 8 years later remains disease-free. Emphasis is made on the low frequency of these tumours, of which only 26 cases are described in the international literature. All these cases have been located in soft areas of the pelvis and the perineum, with the exception of the one presented here, the first one with a vesical location. Clinical behaviour is characterized by the absence of metastasis and a great tendency to local relapse, 70% of cases reported.
