Discussion:



9 years
after the onset of diffuse systemic sclerosis (SSc), she had noticed a gradual
enlargement of a painless swellings gradually developed in various regions such
as a sacral region and bilateral gluteal regions. These elastic masses were 3
cm to 10 cm in diameter. We may encountered a patient with multiple swellings
caused by bursitis accompanied with SSc (systemic sclerosis). Although it is
plausible to speculate that subcutaneous bursitis easily occurs in SSc because SSc
involves microvascular circulation, loose connective tissue, and bony
constitution. Bursitis in SSc can be classified into four types: bursal
calcinosis, dry (or fibrous) bursitis; effusive bursitis; and septic bursitis. Bursitis
generally belong to either bursal calcinosis or septic bursitis occuring at
olecranon and prepatellar region. Bursal calcinosis type is sometimes
accompanied with tuberculosis and staphylococcal infection, consisting of a
large number of rice-sized calcifications in the fluid.
