Male Breast Myofibroblastoma and MR Findings

Abstract

Myofibroblastoma of the breast is a rare benign tumor seen predominantly in men in the sixth to seventh decades of life. We present a case of breast myofibroblastoma in a man and describe the mammographic, sonographic, and MR findings.

Radiologic and Histologic Presentation of Male Mammary Myofibroblastoma

“…Its echogenicity, however, can be hyperechoic, and posterior acoustic shadowing may be present ( 4 ). On magnetic resonance imaging, these lesions typically enhance and can demonstrate internal septations on T2-weighted images ( 5 ). Myofi broblastomas are typically surgically excised with a good prognosis.…”

Invasive papillary carcinoma of the male breast

“…The aim of this imaging study was to demonstrate the morphological features and vascularisation of the mass prior to surgery [14,17].…”

Benign and Malignant Male Breast Diseases: Radiologic and Pathologic Correlation

“…Histopathologically, myofibroblastoma is composed of spindled or oval-shaped myofibroblasts arranged in fascicles surrounded by thick bands of hyalinized collagen ( Figure 6A). Slow growth over several years and rapid growth over several weeks have both been described [7]. The radiologic features of myofibroblastomas are variable.…”
