“…Further studies are required to determine whether a phenomenon similar to the ‘pseudosarcomatous leiomyoma’ exists in canine ureteral tumours. In human medicine, immunohistochemistry is often used in the diagnosis of ureteral leiomyosarcoma and may be useful in assessing whether the tumours in the previous case and our case were indeed both primary ureteral leiomyosarcomas.…”

Leiomyosarcoma is a rarely seen neoplasm of the ureter. Malignant tumors of smooth muscle of the ureter are extremely rare, and about 22 cases of leiomyosarcoma of ureter have been reported to date. A 57‐year‐old diabetic Pakistani man presented with a dull ache pain in the right flank. Past surgical history was three ureteroscopic surgeries for a ureteric stricture. Computed tomography showed a stricture with a peri‐ureteral soft tissue mass of 11 mm x 5 mm at the middle third of the ureter at the level of common iliac vessels. laparoscopic excision with safety margin and right ureterovesical reimplantation is performed. Diagnosis of leiomyosarcoma of the right ureter was made, and one iliac lymph node was excised and was positive for tumor by pathologic examination. Although leiomyosarcoma is rarely seen in urinary tract, it should be considered in the differential diagnosis of ureteral stricture disease and retroperitoneal tumors.

This case report highlights a patient with a leiomyosarcoma originating in the ureter. A chart review was performed on a single patient who presented with a malignant retroperitoneal mass measuring 11.5 × 8.2 × 6.5 cm with subsequent metastasis sites to the breast, pancreas, liver, and lungs. The diagnosis of a leiomyosarcoma is uncommon, accounting for 0.1-0.4% of all cancer diagnoses in the United States. The diagnosis of a leiomyosarcoma originating from the ureter is extremely rare with fewer than 20 reported cases to date. Lack of typical urinary tract cancer signs and symptoms prevented an early presentation, allowing for considerable tumor growth and making complete surgical resection unlikely. We present this case as an example of a rare presentation of a very rare disease and to emphasize the necessity for further research of leiomyosarcoma and early diagnosis
