Benign postoperative spindle cell nodule of the urinary bladder? don't think so.

摘要

According to colleagues specializing in genitourinary pathology, the so-called postoperative spindle cell nodule of the bladder can be extremely difficult to distinguish from a spindle cell sarcomatoid carcinoma. What I have learned in 25 years about spindle cell sarcomatoid carcinoma of the larynx may, by analogy, possibly help with the genitourinary pathology problem.
