Tietze syndrome

Tietze syndrome (also called chondropathia tuberosa or costochondral junction syndrome) is a benign inflammation of one or more of the costal cartilages. It was first described in 1921 by the German surgeon Alexander Tietze (1864–1927).

Tietze syndrome is not the same as costochondritis. Tietze syndrome is differentiated from costochondritis by swelling of the costal cartilages, which does not appear in costochondritis. Like costochondritis, it was at one time thought to be associated with, or caused by, a viral infection acquired during surgery. This is now known not to be the case, as most sufferers have not had recent surgery.
