The American Association of Directors of Anatomic and Surgical Pathology’s (ADASP) reporting system of urinary bladder specimen containing bladder neoplasms is closely similar to the General Rule for Clinical and Pathological Studies on Bladder Cancer‘ by the Japanese Urological Association and The Japanese Society of Pathology, except for several of their new proposals. The Japanese histological grading of transitional cell carcinoma (TCC) is in accordance with the World Health Organization (WHO) classification? On the other hand, in Murphy’s grading system, TCC of the bladder is divided into two categories; low grade (well differentiated) and high grade (moderately to poorly differentiated)? Low grade TCC in Murphy’s classification corresponds to papilloma or grade 1 tumor in WHO, and likewise for high grade TCC to grade 3 tumor. The ADASP state that many tumors classed as grade 2 in WHO would be considered as high grade in Murphy’s classification. In contrast to low grade TCC, almost all high grade tumors in Murphy’s classification have aneuploid DNA while blood group antigen expression (ABH, Lewis a, b and X and Themsen-Friedenreich) is absent or abnormal in approximately 90%. One of the ADASP’s newest observations is the existence of wispy smooth muscle fiber in lamina propria, reminiscent of a muscularis mucosa. They point out that well-developed muscularis mucosa occur in less than 5% of human urinary bladders, and thus the correct identification of these wispy fibers is important for the accurate pathologic staging of bladder neoplasms.
