[Primary nontransitional neoplasms of the bladder].
Revision of all primitive tumours of the bladder diagnosed in our Service between July 1990 and July 1998. Among a total of 703 neoplasms of the bladder only 14 were non-transitional primitive tumours, accounting for just 1.98%. Eleven were malignant neoplasms with a diagnosis of epidermoid carcinoma in nine cases, one adenocarcinoma and one bladder adenocarcinoma. The other three were benign tumours: one haemangioma and two leiomyomas. From a clinical perspective, the predominant symptom was haematuria, followed by irritative symptoms. The two leiomyomas were accidental findings during a gynaecological examination (ultrasound) and a diagnostic examination for a nephritic colic (urography). The diagnostic means used and the extension studies were the same as used for transitional neoplasms. In general, treatment of benign neoplasms was partial cystectomy or transurethral resection while it was radical surgery for the malignant tumours when the existing criteria were an indication for that type of surgery (cystoprostatectomy with bypass), since there are no definite criteria with regards to therapy due to the low incidence of these tumours. Only three of the 11 patients with malignant neoplasms are still alive. All the others died within one year of diagnosis, an evidence of the aggressiveness of these tumours. These cases were considered primitive bladder tumours once it was concluded that there was no relation with any previous or simultaneous transitional neoplasms and that there had been no primitive tumour in a different organ.
