A type of
tumor in which surface
epithelial cells grow downward into the underlying supportive
tissue. It may occur in the nose and/or sinuses or in the
urinary tract (bladder, renal
pelvis,
ureter, urethra). When it occurs in the nose or sinuses, it may cause symptoms similar to those caused by sinusitis, such as
nasal congestion. When it occurs in the
urinary tract, it may cause
blood in the
urine.
blood (blud)
A tissue with red blood cells, white blood cells, platelets, and other substances suspended in fluid called plasma. Blood takes oxygen and nutrients to the tissues, and carries away wastes.
