A case of myofibroblastic pseudosarcomatous tumor of the bladder occurred in a patient previously submitted to TURB is reported. Aim of this investigation is to demonstrate, on the basis of the literature, the importance of histopathology in the diagnosis of bladder pseudosarcoma, since endoscopical and radiological methods can erroneously show a neoplasm. A 65-year-old male patient with hematuria, submitted to ultrasonography and cystoscopy, revealed a bladder superficial papillary formation. A TURB was performed and the histological study showed a superficial bladder cancer (T1-G1-2). After a second hematuria episode with stranguria a new bladder formation was diagnosed and resected; the histological study revealed a bladder pseudosarcoma. The absolute benignity of the lesion and the slight difference in the symptomatology between urothelial carcinoma and pseudosarcoma are underlined. Furthermore, the importance of histopathology to obtain an accurate diagnosis is stressed. The difficulty of a preoperative diagnosis without histopathological examination is pointed out.

Abstract
A case of myofibroblastic pseudosarcomatous tumor of the bladder occurred in a patient previously submitted to TURB is reported. Aim of this investigation is to demonstrate, on the basis of the literature, the importance of histopathology in the diagnosis of bladder pseudosarcoma, since endoscopical and radiological methods can erroneously show a neoplasm. A 65-year-old male patient with hematuria, submitted to ultrasonography and cystoscopy, revealed a bladder superficial papillary formation. A TURB was performed and the histological study showed a superficial bladder cancer (T1-G1-2). After a second hematuria episode with stranguria a new bladder formation was diagnosed and resected; the histological study revealed a bladder pseudosarcoma. The absolute benignity of the lesion and the slight difference in the symptomatology between urothelial carcinoma and pseudosarcoma are underlined. Furthermore, the importance of histopathology to obtain an accurate diagnosis is stressed. The difficulty of a preoperative diagnosis without histopathological examination is pointed out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
