Superficial bladder tumors are classified as non-invasive, and are limited to the superficial layer without invading the bladder muscle. However, even if the tumor is considered non-invasive, it is possible for it to spread to other parts of the body, such as the skin. Skin metastases may appear as nodules or plaques on the skin and may sometimes be accompanied by symptoms such as itching, pain or inflammation. Treatment for skin metastases depends on a variety of factors, such as the size and location of the metastasis, as well as the presence of other metastases in the body. Treatment options may include surgery, radiation therapy, chemotherapy or a combination of these treatments.
