A rare imaging case of bilateral plasmacytoma of the breast

Abstract

This case reports on secondary extramedullary multiple myeloma within both breasts in the absence of axillary nodal involvement and discusses the difficulty in interpretation with clinical recommendations and learning outcomes. Differentiating plasmacytic lesions in the breast is often difficult as clinical and radiological appearances are known to mimic benignity and high-grade primary breast cancer. Extramedullary presentation can determine progression of the disease and can necessitate cross-sectional imaging. Therefore definitive diagnosis is essential as the clinical management of the patient may be altered.

Solitary Plasmacytoma of the Breast: A Case of an Uncommon Breast Neoplasm

“…Clinical presentation, radiographic findings, and biopsy are used in conjunction to come to a definitive diagnosis. While primary plasmacytoma is not a common breast lesion, we report it is a possibility [ 10 , 26 , 27 ].…”

“…Diagnosis with imagining alone is not feasible as SEP lacks specifc radiological and clinical features. When monitoring for disease progression, the imaging modality originally used is preferred to be repeated at follow-up [1,2,4,11,13,[23][24][25][26].…”
