title: Punctate intranodal gold deposits simulating microcalcifications on mammograms.
abstract: Some axillary lymph nodes are frequently seen on mammograms. Rarely, such nodes will demonstrate opacities that appear to be multiple punctate calcific deposits. The literature is of little guidance as to the meaning of this appearance. One report indicates that breast cancers that are manifested as extensive punctate calcifications very rarely occur in this pattern in metastatically involved axillary lymph nodes. The authors suggest that such punctate densities are much more often indicative of intranodal gold deposits and that they occur almost invariably in patients with rheumatoid arthritis who have undergone prolonged chrysotherapy. This observation was confirmed in one patient and suspected in three others with similar clinical histories.
