There was no family history of breast diseases/malignancy. Two years earlier, in another hospital, he underwent an ultrasound examination for breast size increase which showed a unilateral gynecomastia. Two years later, the patient underwent a second clinical examination for a painless palpable mass in right upper outer quadrant, near the nipple. No nipple discharge or retraction were observed. Mammography demonstrated right retroareolar gynecomastia and, in the same side, at the site of the palpable mass, two suspicious contiguous irregular high-density masses with pleomorphic microcalcifications (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>a, b). Breast ultrasonography showed a 7<span class="elsevierStyleHsp" style=""></span>mm, irregular shape, hypoechogenic nodule, which was surrounded by desmoplastic reaction (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). Moreover, a second 18<span class="elsevierStyleHsp" style=""></span>mm hypoechoic lobulated nodule was found (<a class="elsevierStyleCrossRefs" href="#fig0010">Figs. 2 and 3</a>). Breast Imaging Reporting and Data System (BI-RADS) category of both lesions was 4C (highly suggestive of malignancy), and tru-cut biopsy of the two nodules was performed. The histopathological examination, later confirmed after surgery, revealed two synchronous independent primary malignant tumors: the smallest tumor was an invasive ductal carcinoma (histologic grade G2) and the other nodule was an invasive papillary carcinoma (histologic grade G1). Right mastectomy and sentinel lymph node biopsy were performed. Surgical specimen demonstrated free of disease breast surgical margins and no pathological nodes were identified. The final pathologic stage was IA (pT1c, pN0, pM0). Furthermore, immunohistochemical staining of both the tumors was positive for estrogen and progesterone receptor (100%) and HER-2 negative (i.e. molecular subtype LUMINAL-A).</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><elsevierMultimedia ident="fig0015"></elsevierMultimedia></span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0035">Discussion</span><p id="par0015" class="elsevierStylePara elsevierViewall">Male breast cancer is a rare disease (less than 1% of all cancers in men; 1% of all cases are bilateral); the presence of two synchronous primary breast cancers on the same side is even more rare.<a class="elsevierStyleCrossRefs" href="#bib0075"><span class="elsevierStyleSup">1,6</span></a> Moreover, since the left breast is usually more frequently involved, our case (right breast) is uncommon.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">6</span></a> Two were the main reasons explaining the low incidence rate in men: the first is the relatively low amount of breast tissue and the second is the difference in hormonal status.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">6</span></a> The most common histological subtype of male breast cancer is invasive ductal carcinoma (approximately 85% of breast cancer cases in men), followed by papillary carcinoma.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">7</span></a> Invasive papillary breast carcinoma is a subtype of breast cancer that is more frequent in males than in females (5% and 1–2% respectively).<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">7</span></a> According to Nofal MN and Yousef AJ, our report underlines the importance of a triple assessment approach: in fact, in our center the diagnostic work-up include the clinical assessment, radiologic assessment (mammography and ultrasound examination), and tissue biopsy (fine-needle aspiration cytology or core biopsy).<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">8</span></a> Invasive ductal carcinoma usually appears as dense mass with irregular borders and spiculations on mammography corresponding to a solid, hypoechoic, ill-defined mass on ultrasound.<a class="elsevierStyleCrossRefs" href="#bib0105"><span class="elsevierStyleSup">7,9</span></a> On the other hand, papillary carcinoma usually appears as a well-circumscribed mass with occasional microcalcifications.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">6</span></a> Ill-defined borders point out infiltrative component.<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">9</span></a> Though in our case it had a solid appearance, the typical sonographic presentation of papillary carcinoma includes a solid well-circumscribed mass or a complex cystic mass with thick walls containing both solid and cystic components.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">7</span></a> In our case, the different ultrasonographic presentation of the two nodules was highly suspicious of two different histological tumor types so biopsy was carried out from both the nodules.
