ABSTRACT
Background: Non-Hodgkin lymphoma (NHL) of the breast is a rare disease and can occur amongst patients affected by Waldenström's Macroglobulinemia (WM). WM is an indolent B-cell lymphoproliferative disorder with an overall incidence of about 1/100,000 in Europe. Breast imaging is not specific to breast lymphoma that often mimics benign lesions. The diagnosis is based on breast biopsy, the presence of MYD88L265P somatic mutation and immunoglobulin M (IgM) paraprotein detectable in the setting of lymphoplasmacytic infiltration by bone marrow (BM) biopsy. Case Description: A 60-year-old woman with personal and familial history of monoclonal gammopathy of undetermined significance (MGUS) and a lump in her right breast was referred to our hospital. Standard imaging showed round mass with smooth edges. The lump was biopsied and the pathology examination showed lymphoplasmacytic lymphoma (LPL) of the breast which led to final the diagnosis of WM. Conclusions: Lymphoma of the breast is a rare disease, often misdiagnosed because of the lack of specific features at mammogram and ultrasound. Core biopsy is crucial to make diagnosis of breast lymphoma and early diagnosis of WM has been shown to improve overall survival (OS). A comprehensive approach is required in order to assess patients affected by blood disorders presenting with a new breast mass that can lead to diagnosis of breast lymphoma.
ABSTRACT
BACKGROUND: We retrospectively evaluated safety and performance of magnetic seed localisation of nonpalpable breast lesions. METHODS: We reviewed records of patients with nonpalpable breast lesions preoperative localised by placing magnetic Magseed® marker between February 2019 and December 2020. During surgery, Sentimag® magnetic probe was used to localise the marker and guide surgery. Safety, lesion identification and excision with tumour with free margins and re-excision rate were assessed. RESULTS: A total of 77 Magseed® devices were placed into the breasts of 73 patients, 44 under ultrasound and 33 under stereotactic guidance (4 bilateral). All devices were retrieved as were the target lesions. Magnetic marker placement was successful in all cases without any adverse event. Intraoperative identification and excision of the localised lesion were successful in 77 of 77 of cases (100%). In three cases (all of them calcifications with the seed placed under stereotactic guidance), the seed did not reach the exact target position of the biopsy clip; thus, larger excision was needed, with localisation failure attributed to incorrect clip insertion (n = 1) or to clip dislocation (n = 2). Migration of the marker was negligible in all patients. Complete excision after the initial procedure with at least 1-mm disease-free margins was obtained in 74 out of 77 (96.1%) lesions. The re-excision rate was 3 out of 77 (4%). CONCLUSIONS: Magnetic marker localisation for nonpalpable breast lesions was safe, reliable, and effective in terms of lesion identification, excision with tumour-free margins and re-excision rate.

Here we report a case of 50-mm lump within the left breast in a 56-year-old man. The patient underwent left total mastectomy and sentinel node biopsy. The pathology report showed low-grade intracystic papillary breast carcinoma surrounded by ductal carcinoma in situ. Sentinel node biopsy was negative. The patient was prescribed five years tamoxifen.
ABSTRACT
Angiosarcoma of the breast is one of the rarest malignancies. Breast angiosarcoma can be classified into primary when arising de novo and secondary to chronic lymphoedema or breast irradiation. Molecular pathways involved in angiosarcoma development have not been described clearly, yet some gene point mutations and protein altered expression levels have been detected. So far, their management is based above all on surgery. Hence, further studies starting from the few known key points may help to develop more effective strategies based both on target therapies, together with surgery.
