If the diagnostic term in the pathology report is not in the list below, be sure to consult ICD-O.
Transitional cell carcinoma--81203; most common morphology
Papillary carcinoma--81303
Papillary and transitional cell carcinomas comprise 90-95% of all bladder cancers.
Squamous cell carcinoma (80703)--occurs in 8% of all bladder carcinomas.
Adenocarcinoma (81403) of the bladder--very rare (2%) and almost impossible
to distinguish from primary prostate carcinoma which has extended into the
bladder.
Leiomyosarcoma--88903; rare tumor arising in the muscle layer of the bladder.
Sessile (flat or attached by a broad base)--infiltrating type; spread widely
through the bladder wall and surrounding structures; less gross tumor formation
in the bladder lumen.
Papillary--most bladder tumors; will often occur and recur in multiple sites
within the bladder. Papillary carcinomas are more frequently single, firmer,
have broader stalk than benign tumors and form large, bulky, cauliflower-like
growths.
Synonyms for /2 behavior (carcinoma in situ, intraepithelial, noninfiltrating, noninvasive): CIS, Stage 0, confined to epithelium, intraepithelial, involvement up to but not including the basement membrane, noninfiltrating, noninvasive, no stromal involvement, papillary noninfiltrating, noninvasive papillary, and, uniquely for bladder, stage "Ta".
