Abstract
|
|
|
|
``Rice body`` is a soft tissue nodule resembling shiny white rice-bean, which is occasionally observed at the juxta-articular area among patients with rheumatic arthritis and tuberculosis arthritis. A 45-year-old man was presented with tender cystic tumor on the volar aspect of the left third finger, which was noted 5 months prior to the visit. When performing a biopsy, numerous, whitish granular, 5∼10 mm in size, and ovoid substances were observed, and found to be the major component of the cystic tumor. Histologically, the granules were consistent with the so-called ``rice bodies`` (granules of inner acidophilic material surrounded by fibrin/collagen). With these findings, we report a case of rice body-containing cystic tumor clinically reminiscent of other cystic lesions, which can be seen on the finger around the joint structure.
