title: An increase of blood squamous cell carcinoma antigen in Pseudomonas aeruginosa spondylitis.
abstract: Squamous cell carcinoma antigen (SCCA) is traditionally engaged for detecting and following up malignancy from a squamous cell origin. We encountered an unusual increase of blood SCCA but no other cancer markers in a patient associated with an infective lumbar spondylitis due to Pseudomonas aeruginosa. An overshooting of Th1 expression, such as tumor necrosis factor alpha, bumped up by his uremia as a result of P. aeruginosa infection may hasten SCCA. Therefore, SCCA might additionally serve as a serological marker for infection besides squamous cell cancer, and its false-positive increase also highlights the appropriateness of tumor marker screening.
