“…Recent studies in the radiology literature of Brazil have addressed the importance of imaging in the management of breast cancer ( 20 - 27 ) . Previous studies had corroborated the ability of CESM to detect primary breast tumors and demonstrated that its accuracy in preoperative tumor staging with lesion size measurement is comparable to that of MRI.…”

ObjectiveTo assess the feasibility of contrast-enhanced spectral mammography (CESM) of the breast for assessing the size of residual tumors after neoadjuvant chemotherapy (NAC).Materials and methodsIn breast cancer patients who underwent NAC between 2011 and 2013, we evaluated residual tumor measurements obtained with CESM and full-field digital mammography (FFDM). We determined the concordance between the methods, as well as their level of agreement with the pathology. Three radiologists analyzed eight CESM and FFDM measurements separately, considering the size of the residual tumor at its largest diameter and correlating it with that determined in the pathological analysis. Interobserver agreement was also evaluated.ResultsThe sensitivity, specificity, positive predictive value, and negative predictive value were higher for CESM than for FFDM (83.33%, 100%, 100%, and 66% vs. 50%, 50%, 50%, and 25%, respectively). The CESM measurements showed a strong, consistent correlation with the pathological findings (correlation coefficient = 0.76-0.92; intraclass correlation coefficient = 0.692-0.886). The correlation between the FFDM measurements and the pathological findings was not statistically significant, with questionable consistency (intraclass correlation coefficient = 0.488-0.598). Agreement with the pathological findings was narrower for CESM measurements than for FFDM measurements. Interobserver agreement was higher for CESM than for FFDM (0.94 vs. 0.88).ConclusionCESM is a feasible means of evaluating residual tumor size after NAC, showing a good correlation and good agreement with pathological findings. For CESM measurements, the interobserver agreement was excellent.

“…Breast soreness, swelling, warmth, and erythema are common symptoms, and they might mimic other inflammatory diseases like mastitis or abscess. In cases where symptoms are chronic or get worse, it is crucial to take the possibility of cancer into account [ 2 ]. The patient in this case report had early diagnostic testing, including a core needle biopsy, which showed significant lymphocytic infiltration that was consistent with lymphocytic mastitis.…”

“…Clinically and radiologically, the lesion may mimic breast carcinoma. While the condition is relatively uncommon, it can cause significant discomfort and pose diagnostic challenges [ 2 ]. This case report aims to describe a case diagnosed as lymphocytic mastitis on imaging and biopsy and to highlight the findings of an infiltrating ductal carcinoma (IDC) discovered during a mastectomy procedure executed due to the persistence of symptoms.…”

A rare inflammatory breast disorder called lymphocytic mastitis is characterized by lymphocyte infiltrates in the mammary parenchyma. Due to their rarity, incidental observations of invasive ductal carcinoma in lymphocytic mastitis present diagnostic and management challenges. We present a case of a 52-year-old female with a history of painfully swollen breasts for three months who underwent a core needle biopsy, consistent with lymphocytic mastitis on histopathology. Due to persistent and worsening symptoms, a mastectomy was performed. During the examination, an incidental finding of infiltrating ductal carcinoma was identified in the mastectomy specimen. This unexpected discovery led to further investigations and altered the patient's treatment plan. The detection of invasive ductal carcinoma in the presence of lymphocytic mastitis highlights the importance of continuous surveillance and thorough examination. In the circumstances of lymphocytic mastitis, it is vital to take the likelihood of concurrent malignancy into account, especially when symptoms persist or reappear after appropriate management. This case report seeks to raise awareness among physicians of this exceptional association and drive further research that will explain its pathophysiology while enhancing management strategies.
