On a pathological specimen of breast cancer cells, retraction artifact during histological processing mimics true lymphovascular invasion (LVI). The accurate determination of the presence or absence of LVI is a factor in determining risk of having a positive sentinel node, or having additional positive axillary nodes after a positive sentinel node biopsy in women with early-stage breast cancer. The determination of nodal risk influences the decision of the treating physicians as to whether a sentinel node biopsy or completion axillary dissection is necessary. On slide preparation, ideal factors favoring true LVI include: a definite endothelial lining, with endothelial nuclei that …
