[Intravesical hemangiopericytoma]. / Hemangiopericitoma intravesical.

OBJECTIVE: To report on a case of hemangiopericytoma of the urinary bladder mimicking a urothelial tumor. METHODS: A case of hemangiopericytoma arising from the urinary bladder in a 78-year-old man is described. The initial symptoms included gross hematuria, and it was confused with a urothelial tumor. The difficulty in making the diagnosis in regard to the site of origin and histological findings are discussed. The literature is briefly reviewed. RESULTS/CONCLUSIONS: Ultrasound and urographic evaluation showed an intravesical mass which was suspected to be a urothelial tumor. The patient was submitted to transurethral surgery. Histological analysis and immunohistochemical techniques demonstrated a hemangiopericytoma.

[Bladder malacoplakia: apropos of 2 cases]. / Malacoplaquia vesical: a propósito de dos casos.

OBJECTIVES: To describe two cases of malakoplakia of the bladder with an unusual form of presentation and review the cases previously reported in the literature. METHODS/RESULTS: Two patients, a 61-year-old female and a 71-year-old male, are described. Both patients had a history of recurrent infection caused by coliform pathogens. Treatment consisted of trimethoprim sulfamethoxazole, ascorbic acid and bethanecol chloride, together with extended TUR of the bladder lesion. CONCLUSIONS: Although malacoplakia of the bladder is considered to be a benign disease, close follow-up is warranted due to frequent recurrence of symptoms and the difficulty in achieving long-lasting effects since it is frequently associated with immunosuppression.
