The introduction of breast tomosynthesis into our practice was associated with a significant reduction in recall rates and a simultaneous increase in breast cancer detection rates.
Breast conservation therapy for breast cancer involves lumpectomy or segmental mastectomy followed by radiation therapy. Masses, fluid collections, architectural distortion, scarring, edema, skin thickening, and calcifications are posttreatment findings that may mimic or mask local tumor recurrence. Despite the overlap between posttreatment changes and tumor recurrence, the two entities can usually be distinguished by the characteristic mammographic appearances of posttreatment sequelae and by comparing interval findings on successive studies. Postoperative masses and fluid collections slowly diminish in size and usually resolve by 1 year after surgery. Radiation-induced edema gradually resolves; increasing edema may be due to recurrent cancer. Postsurgical scarring usually appears as a poorly marginated soft-tissue mass with interspersed radiolucent areas. Recurrent cancer is usually seen as a mass with no central radiolucent areas. Pleomorphic and granular microcalcifications are important markers for recurrent cancer and can usually be distinguished from the thick, calcified plaques and elongated dystrophic calcifications associated with scarring.
This is a case of a large lactating adenoma which developed in a 26 year old primagravida during the third trimester of her pregnancy. The presentation was that of a grossly enlarged and engorged breast with breast erythema, warmth and tenderness. Radiologic and pathologic examinations were difficult because of the lactational changes in the breast and areas of infarcted tissue within the large tumor. Skin biopsies and core biopsies of the mass were performed to exclude malignancy. Surgical resection of the mass was necessary for definitive diagnosis. The pathology proved to be a lactating adenoma, which is the most prevalent breast mass in young pregnant females. The large size of this tumor, and the presentation of breast erythema and edema raised the possibility of inflammatory breast cancer. Following surgical resection and definitive diagnosis of this tumor, the patient required plastic surgical reconstruction of the breast because of redundant breast tissue. Although most lactating adenomas spontaneously involute, the diagnosis is not always straight-forward and surgical resection may be required for definitive diagnosis and exclusion of other pathologic processes.
Breast pain represents an area of overutilization of health care resources. For female patients who present with pure breast pain, breast imaging centers should consider the following imaging protocols and education for referring physicians: an annual screening mammogram should be recommended for women 40 years or older, and reassurance without imaging should be offered to patients younger than 40 years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
