[Calcium pyrophosphate deposition (CPPD) disease - more than just "pseudogout"].

Calcium pyrophosphate deposition (CPPD) disease plays an important - and sometimes underestimated - role in rheumatology practice. Clinically, CPP-arthritis is often indistinguishable from gout and is therefore commonly referred to as "pseudogout". In contrast to gout, CPPD cannot be cured but can only be treated symptomatically. The pathophysiology, diagnosis, therapy and new therapeutic approaches to CPPD are discussed below.
