Spindle cell proliferations of the urinary bladder are uncommon but may cause significant diagnostic difficulty resulting from the degree of morphologic overlap between clinically benign and malignant lesions. These difficulties may be amplified in small biopsies because some of the more specific diagnostic features may not be present for evaluation. In addition, the number of different diagnostic terms applied to the same entity has added confusion to this diagnostic area. This review discusses the nomenclature, morphologic criteria, and immunohistochemical features used to classify spindle cell proliferations occurring in the urinary bladder, including those with myofibroblastic, smooth muscle, skeletal muscle, epithelial (sarcomatoid urothelial carcinoma), fibroblastic, and neural differentiation. A separate discussion of 5 challenging differential diagnostic scenarios is also presented.

“…A retrograde ureterography is rarely necessary, except in cases where inadequate visualization is obtained by IVU [10]. The retrograde study demonstrates a sharply defined, smoothly outlined filling defect that in some cases can be luxated in a retrograde direction by injection of contrast medium.…”

“…Classically fibroépithélial polyps are seen as a 'cork screw' filling defect in the upper ureter [16]. There is usually no severe obstruction or renal damage even with relatively large lesions [10]. Less frequently, hydro(uretero)nephrosis, or a nonfunctioning kidney is found.…”

“…In most cases colicky or a rather nonspecific loin pain and/or hematuria is the leading symptom [3], Hematuria was reported in more than 50% [10]. Colics can be due to intermittent blocking or to ureteral intussusception [7], In children it could present as a UPJ obstruction [2], In 1 child albuminuria and leucocyturia incited further radiologic exploration [13].…”

“…Mostly en bloc resection of the tumor-bearing segment of the ureter is advocated [16]. Local excision can be done when the ureteral stalk is very small [10] or when multiple pol yps are present [16]. When there is extensive ureteral involvement, ureteral substitution by small bowel or au totransplantation should be considered.…”
