In breast cancer surgery, establishing a diagnosis other than lymph node metastasis of breast cancer, when performing a sentinel node biopsy in individuals with breast cancer, is rare. Here, we report a case of incidental discovery of follicular lymphoma by sentinel lymph node biopsy for Paget’s disease associated with invasive breast cancer. A 60-year-old female initially presented with erosion on her left nipple and was clinically diagnosed with stage IA human epidermal growth factor receptor type 2 (HER2)-positive breast cancer and Paget’s disease. Accordingly, skin-sparing mastectomy, sentinel lymph node biopsy, and immediate breast reconstruction were performed. Although an intraoperative pathological examination of frozen sections of lymph nodes presented no evidence of metastasis, it revealed large follicles. Based on immunohistochemistry of the additional lymph nodes, she was diagnosed with follicular lymphoma. Therefore, we initiated chemotherapy for follicular lymphoma followed by trastuzumab. At present, 6 years after the operation for breast cancer, the patient is doing well.
We experienced a case of hemorrhagic infarction of the ovarian fibroma and that indicated the characteristic following appearance: exhibiting a high signal intensity area observed at the periphery of mass on T1-weighted MRI (magnetic resonance imaging). It was thought that this appearance developed because hemorrhagic infarction was caused by subacute ovarian torsion. This is a useful finding for suspecting hemorrhagic infarction preoperatively.
Background:
There is no decrease in the number of breast cancer deaths if screening mammography is performed in women aged <40 years. However, NCCN guidelines recommend screening mammography in young women at risk of hereditary breast cancer. Therefore, more accurate screening mammography for young women is needed.
Objective:
To evaluate the features of screening mammographic findings, particularly microcalcifications, in women aged <50 years to increase the positive predictive value of screening mammography in young women.
Methods:
We retrospectively reviewed the data of consecutive women who underwent opportunistic and organized breast cancer screening at the Sakuragaoka Hospital (Shizuoka, Japan) between April 2013 and March 2015. We compared the mammographic findings and features of microcalcifications between women aged <40 and 40–49 years and those aged 50–74 years.
Results:
The study included 3645 women. Of these 3645 women, 415 (11.4%) were aged <40 years, 1219 (33.4%) were aged 40–49 years, and 2011 (55.2%) were aged 50–74 years. Women aged <50 years were more likely to be recalled for microcalcifications than those aged 50–74 years (<40 years, 4.8%; 40–49 years, 4.3%; 50–74 years, 3.3%). Young women were more likely to be recalled for small round and segmental microcalcifications [<40 years, odds ratio (OR): 1.799 (95% CI: 0.751–2.846); 40–49 years, OR: 1.394 (95% CI: 0.714–2.074)] and less likely to be recalled for small round and grouped microcalcifications [<40 years, OR: 0.603 (95% CI: 0.181–1.025); 40–49 years, OR: 0.961 (95% CI: 0.496–1.428)] compared with women aged 50–74 years.
Conclusions:
On screening mammography, women aged <50 years had a higher tendency to be recalled for microcalcifications, particularly small round and segmental microcalcifications. False-positive results may be reduced by reflecting the characteristics of microcalcification findings among young women without breast cancer in the future.
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.
