I have never seen such description. It does not look like pathology report as it does not say grade or stage of the tumor samples.
According to internet, a neoplasm is an abnormal growth of tissue that can be benign (noncancerous) or malignant (cancerous), so malignant neoplasm of bladder seems to mean bladder cancer. Unspecified means the location or type of the tumor was not specified.
“Malignant neoplasm of bladder, unspecified” is the description of code C67.9 which is billable code. ICD-10-CM is international classification of disease. The US developed a clinical modification (ICD-10CM) for medial diagnoses based upon WHO’s ICD-10 and CMS developed a new Procedure Coding System. See blow the coding system and its description. The urologist who examined your bladder should know the location of the tumor. So, I do not know why the location of the tumor was unspecified. Also, I do not know who prepared the report and gave it to you. See the link below.
