If it is true, you must report. Patient may have invasive carcinoma. If this is total mastectomy specimen, you need to gross the specimen and submit more sections. If it is a partial mastectomy, you have to submit entire specimen for microscopic examination.

If you are not sure if it is lymph-vascular invasion, you can do endothelial staining, such as D2-40 and CD31.
