Tiny, rounded calcifications occurring in the skin. A benign fibroma containing fatty elements. During involution, when glandular tissue is replaced by fat, the fat assumes a honeycomb appearance. This fat is then encapsulated and displaces adjacent tissue to form an obvious abnormality. It is considered a marker for increased risk of development of breast cancer.
Axillary nodes are oval shaped with a fatty hilum.
These are seen along the chest wall all the way down to the nipple line. They are usually less than 2.5 cm and should be regarded as suspicious if any larger. They can be seen in the upper outer quadrant posteriorly. A hilar notch is noted and its center is lucent due to fatty replacement. If these nodes are greater than 1 cm and contain a homogeneous density throughout the node, they should be regarded as suspicious.
