“…Because breast tissue is radiosensitive and exhibits higher density on mammography in childhood, US evaluation has been suggested as the first-choice diagnostic modality. Although most childhood breast masses are benign, being aware of ultrasonographic and Doppler characteristics of both common breast masses and less common pathologies is important [27]. Vascularity patterns of fibroadenomas as common benign breast lesions have been categorized as segmental, capsular, and feeding vessels; the average number of vessels was found to be 3.5 in mixed-type fibroadenomas (range 2-5) [28].…”

“…RMS metastasis to the breast presents as either subcutaneous or parenchymal nodules [32]. Imaging features of RMS on US have been described as solitary lesions with a nodular appearance [27], bilateral diffuse involvement with a lobulated infiltrative hypoechoic pattern [33], lobulated well-circumscribed hypoechoic lesions with irregular margins, diffusely nodular infiltrations without a normal breast architecture [34], having a long axis perpendicular to the skin, and as heterogeneous. RMS may also present with posterior enhancement or indifferent shadowing [35].…”

Primary Rhabdomyosarcoma of the Breast: Imaging Findings and Literature Review

Background: Primary breast rhabdomyosarcoma (RMS) can occur in children. There is a lack of knowledge regarding radiologic findings and added diffusion-weighted magnetic resonance imaging (MRI) features of RMS in the literature. Case Report: A 12-year-old girl was diagnosed with primary alveolar RMS of the breast. Gray scale ultrasound revealed posterior acoustic enhancement behind a well-circumscribed, multilobulated hypoechoic mass. Doppler ultrasound revealed increased peripheral and central vascularity. Hypointense septations on T2-weighted image exhibiting more enhancement than the stroma on late gadolinium-enhanced images were striking within a hyperintense mass. A hyperintense hemorrhagic focus on T1-weighted image was present in the absence of any necrosis. Avid enhancement on early postcontrast images proceeding from the periphery to the center was depicted. Conclusion: A rapidly enlarging mass with an echogenic peripheral rim together with posterior acoustic enhancement on gray scale ultrasound, intense vascularity on Doppler ultrasound, axillary lymphadenopathy, and satellite nodules on MRI should raise suspicion. Enhancing central and peripheral septations are suggestive of RMS. Dynamic contrast-enhanced MRI in suspected cases can provide valuable data in the differential diagnosis.

“…In addition, a differential diagnosis with primary breast cancer may also be difficult. [1][2][3] However, this is essential to determine treatment and prognosis. A prompt and accurate diagnosis is therefore essential to avoid unnecessary mastectomy and select appropriate chemotherapy and radiation therapy.…”

“…[1][2][3] Lung carcinoma and prostate carcinoma are the most common primary tumors that metastasize to the male breast. 4,5 To our knowledge, there are only 2 published cases of metastases to the breast from colorectal carcinoma occurring in men, although colorectal carcinoma is one of the most common tumors in adults. 6,7 Metastases to the breast from extramammary malignancies are characterized by the extraductal location of the tumor, lack of in situ carcinoma, and the absence of desmoplastic reaction.…”

Metastasis to the breast from an adenocarcinoma of the colon

Metastases to the breast from extramammary malignancies are rare. We report a case of metastasis to the breast from a colonic adenocarcinoma in a 50-year-old man who was 6 years status after a right hemicolectomy for T3N1M1 adenocarcinoma of the ascending colon. Sonographic evaluation of the right breast lump showed a hypoechoic mass with slightly irregular margins, but there was no internal vascularity. Chest CT also documented a poorly enhancing suspicious mass in the right breast. The diagnosis of adenocarcinoma metastasis to the breast was achieved with sonographically guided core biopsy.
