“…In humans with bladder wall leiomyosarcoma, chronic hematuria is a consistent clinical finding. 13,16,17,20,23,29 The dog in our report with bladder wall leiomyosarcoma (dog 3) had a history of hematuria, both 9 months before presentation, and at the time of surgery.…”

Smooth muscle origin neoplasia of the urinary bladder wall is rare in dogs. This report describes the ultrasonographic features of two bladder wall leiomyomas and one bladder wall leiomyosarcoma. All three dogs had a single, smoothly marginated, round, hypo to mixed echogenicity intraluminal mass in the urinary bladder. Based on color Doppler examination of the masses, there was no visible blood flow.

“…Excretory urography is characterized by filling defects within the bladder for both leiomyoma and leiomyosarcoma. 12,16 Excretory urography is preferred because the involvement of the ureter(s) can be evaluated at the same time. Calcification of the leiomyosarcomas had been reported.…”

A case of advanced leiomyosarcoma of the urinary bladder is reported in a 25-year old man who, in a short time, experienced a complete ‘spontaneous’ regression of his fatal illness. He first presented with severe haemoperitoneum resulting from an unresectable bleeding tumour of the urinary bladder. Debulking surgery was performed, followed by salvage chemotherapy. Histological and ultrastructural examinations of the tumour confirmed a poorly differentiated leiomyosarcoma. The residual disease failed to respond to salvage chemotherapy, but regressed ‘spontaneously’ 5 months after cessation of therapy. The patient is alive without evidence of disease 51 months after the diagnosis. This remarkable phenomenon and relatively long survival in a poor-risk leiomyosarcoma of the urinary bladder has never been reported previously.

“…Pathological examination revealed T1, grade 2 papillary transitional cell carcinoma and focal muscle invasive leiomyosarcoma, respectively ( figure 1 and figure 2). Transitional cell carcinoma was composed of a central fibrovascular core that is covered by [8][9][10] - reported in the literature (1)(2)(3)(4)(5)(6) . Of these 7 cases, the carcinomas were transitional cell carcinoma in all cases and the sarcomas were leiomyosarcoma in 6 cases and osteogenic sarcoma in 1 case.…”

Smooth muscle neoplasms of the urinary bladder are rare, and the majority of them are leiomyosarcomas followed by leiomyomas of conventional histopathological type. Simultaneous occurrence of transitonal cell carcinoma and sarcoma as two separate primary tumors in the bladder is very rare. A new case of coexisting leiomyosarcoma and transitional cell carcinoma of the urinary bladder is presented.C Ca as se e R Re ep po or rt t A 65-year old man presented with a threemonth history of painless gross hematuria, dysuria, urinary frequency and nocturia. An intravenous pyelography revealed normal upper urinary tract and a filling defect on the left lateral wall of the bladder. Pelvic computed tomography (CT) showed two solid papillary masses measuring 4x5 cm and 2x2 cm on the posterolateral wall of the bladder. No retroperitoneal adenopathy or metastases were found. Cystoscopic examination revealed a 4x5 cm polypoid, broad-based tumor on the left-posterior wall of the bladder. In addition, a 2x2 cm smooth polypoid mass with intact surface was determined above this tumor. These tumors were resected transurethrally and intravesical mitomycin-C was administered as a single instillation. Pathological examination revealed T1, grade 2 papillary transitional cell carcinoma and focal muscle invasive leiomyosarcoma, respectively ( figure 1 and figure 2). Transitional cell carcinoma was composed of a central fibrovascular core that is covered by 8-10 - ---------------------------------------------------------------------------------------------------

Bladder leiomyosarcoma: Report of three cases

Abstract: Three patients with leiomyosarcoma of the urinary bladder are presented. One case showed urothelial carcinoma in situ also. The mode of presentation and operative findings were similar in two female patients, whereas the lesion seemed to be more aggressive in a male patient.
