C alcium pyrophosphate dehydrate crystal deposition disease
(CPPD) is an inflammatory arthritis produced by the deposition
of calcium pyrophosphate crystals. The pathogenesis is not fully
understood, but some risk factors were associated such as aging,
previous trauma or somemetabolic conditions. The involvement of
joints like themetacarpophalangeal, whicharenot typicallyaffected
by osteoarthritis, should raise the suspicion of CPPD. Diagnosis is
based on the clinical manifestations, radiographic and laboratory
findings. The author presents a case report in which occupational
exposure, through the contribution of chronic microtrauma,
appears to be the main etiological factor for CPPD, an association
never reported before. This case refers to a 63-year-old man, who
worked as amedical pathologist for 30 years, specialized in cellular
microscopy. His daily tasks consisted of using the microscope
about eight hours per day and involved highly repetitive precision
movements of fingers and hands at high rate with insufficient
recovery time. After 25 years in this job, he gradually developed
complaints of bony enlargement, tenderness, warmth, erythema
and swelling referred to the metacarpophalangeal and 1st
interphalangeal joints of the 2nd and 3rd right fingers. Secondary
causes of CPPD were excluded and the immunological study
was normal, but the radiographic images showed intra-articular
calcifications and arthritis in the metacarpophalangeal joint of
the 3rd finger of the right hand and marginal osteophytosis in this
topography, with the deposition of calciumpyrophosphate crystals.
This case opens the possibility of a new etiology for CPPD as well
as this classification as a work-related disease.
