Rare case of male breast cancer and axillary lymphoma in the same patient: an unique case report

Synchronous early-stage breast cancer and axillary follicular lymphoma diagnosed by core needle biopsy: A case report

Synchronous double cancers are an infrequent finding. The focus of this study was a case of diagnosed synchronous double breast cancer (BC) and axillary (Ax) follicular lymphoma (FL). The patient was a 73-year-old woman who had been visiting her local doctor for follow-up of a fibroadenoma of the left breast, and was referred to our hospital after being diagnosed with invasive ductal carcinoma (IDC) of the left breast. Ultrasonography (US) revealed enlarged Ax lymph nodes (LNs) and US-guided core needle biopsy (CNB) was performed. CNB revealed no metastasis of IDC; however, a diagnosis of FL was made. Therefore, the patient was diagnosed with synchronous double BC and Ax FL and underwent partial surgical resection of the BC and close monitoring of the FL. To the best of our knowledge, this is the first case of malignant lymphoma diagnosed by CNB of Ax LNs during preoperative BC screening. CNB allows for a shorter waiting time for the examination, and it is considered to be minimally invasive, cost-effective and non-inferior to surgical resection in terms of specimen volume. Therefore, active preoperative evaluation of Ax LNs using US-guided CNB may contribute to BC staging, and may also help diagnose synchronous cancers.

Multiple Primary Malignant Neoplasms: A Case Report of Breast Mucinous Carcinoma and Extramammary Diffuse Large B-Cell Lymphoma in a Male Patient

Multiple primary malignant neoplasms refer to two or more malignancies in an individual that are not related. We report a case of a 78-year-old male with concurrent breast mucinous carcinoma and extramammary lymphoma. The patient initially presented with palpable masses in the left breast and the right groin, which were pathologically confirmed after a surgical biopsy as breast mucinous carcinoma and diffuse large B-cell lymphoma, respectively. He underwent whole-body 18-fluorine deoxyglucose PET/CT before surgery, and an enhancing nodular lesion in the left lingual tonsil was found incidentally. It was later confirmed as a diffuse large B-cell lymphoma, a pathology of the same type as the right inguinal mass. Unspecified lymphadenopathies in breast cancer patients may easily be considered as metastatic lesions. However, this case suggests that lymphomas should be included in the differential diagnoses to avoid misdiagnosis and treatment delay, especially in older adult patients.

Double-hit lymphoma of the male breast: a case report

Background

Whereas lymphoma of the female breast is already rare, lymphoma of the male breast has only anecdotally been reported. Within a study of 32 lymphoma of the breast reported between 1973 and 2014 as Burkitt lymphoma, we observed a single male case, which we report here.

Case presentation

A 72-years-old Caucasian man presented with a mass in his left breast. Clinical history included prior basal cell carcinoma, leiomyosarcoma, and administration of spironolactone. The reference pathology diagnosis at presentation was Burkitt lymphoma according to the Kiel Classification. The present re-investigation using fluorescence in situ hybridization revealed an IGH-MYC translocation and a break in the BCL2 locus in the tumor cells. Thus, in light of the current WHO classification, the diagnosis was revised to high-grade B-cell lymphoma with MYC and BCL2 rearrangement, Burkitt morphology (so-called “double-hit” lymphoma). Genome-wide chromosomal imbalance mapping revealed a complex pattern of aberrations in line with this diagnosis. The aberrations, including copy-number gains in chromosomes 3q and 18 and focal homozygous loss in 9p21.3, resembled typical changes of lymphomas affecting “immune-privileged” sites.

Conclusion

The present case adds to the understanding of the pathogenesis of male breast lymphomas, about which hardly any molecular characterization has been published yet.

Random synchronous malignancy in male breast: a case report

We report here a case of a random synchronous male breast malignancy in a patient with a known base of tongue malignancy that was incidentally detected on a whole body 18-fluorine deoxyglucose positron emission tomography and computed tomography (¹⁸F-FDG PET/CT). Patient was referred to us for PET/CT staging and radiotherapy planning for a poorly differentiated squamous cell carcinoma of base of tongue. Histopathologically, the incidentally detected breast lesion was proven to be an invasive ductal carcinoma. ¹⁸F-FDG PET/CT being a whole body imaging modality is known to detect a considerable number of synchronous primaries. Synchronous malignancies in the head and neck area and the upper aerodigestive tract are well established. However, synchronous malignancy in male breast is reportedly uncommon. Our case is unique for the fact that a random synchronous dual malignancy of base of tongue and breast in a male patient was detected during a whole body ¹⁸F-FDG PET/CT imaging.
