“…Although its cytomorphological features are similar to those of MFB, fibromatosis mimics breast carcinoma radiologically and clinically. Nonetheless, cytopathologists should be aware that MFBs seldomly show ill‐defined borders radiologically 19‐21 . Nodular fasciitis, on the other hand, creates a noncalcified, spiculated mass and architectural distortion that are observable via mammography.…”

Myofibroblastoma (MFB) is a rare benign spindle cell tumor originating from myofibroblasts in the breast stroma. MFB typically presents as a slow‐growing, well‐circumscribed, solitary mass ranging from 1 to 4 cm in size. It has been reported in adults, and frequently seen in older males and in postmenopausal females. The lesion is composed of stromal cells showing fibroblastic and myofibroblastic differentiation at the morphological, immunohistochemical and ultrastructural levels. To date, the literature includes only about 24 MFB cases confirmed via fine‐needle aspiration and cytological evaluation. Here, we present a patient with MFB that was diagnosed via conventional smear slides and cell block, in addition to immunohistochemical analysis.

“…Mammographically, it commonly appears as a well-circumscribed high density mass without calcification (Fig 2 .). On ultrasound, the mass has a homogenous hypo to hyperechoic appearance with minimal posterior shadowing [22]. Histologically, spindle cell breast lipomas are composed of bland spindle cells intermingled with mature adipocytes, and collagen bundles (Fig.…”

“…7). A well-defined hypoechoic mass is typically seen on ultrasound with or without variable degree of posterior acoustic shadowing [22]. Varying degrees of collagen and adipose tissue are seen with histological features sometimes mimicking those of spindle cell carcinoma of the breast, which can lead to misdiagnosis [49].…”

“The unusual suspects”—Mammographic, sonographic, and histopathologic appearance of atypical breast masses

Breast malignancy is the second most common cause of cancer death in women. However, less common breast masses can mimic carcinoma and can pose diagnostic challenges. This case-based review describes a spectrum of rare breast neoplastic and non-neoplastic masses ranging from malignant to benign entities. Malignant masses in this review include adenoid cystic carcinoma, spindle cell lipoma, granular cell tumor, angiosarcoma, glomus tumor, adenosquamous carcinoma, and myofibroblastoma. Benign masses include sarcoidosis, diabetic mastopathy, and cat scratch disease. Demographics and, when relevant, clinical presentation are summarized. Breast imaging appearance on mammography and ultrasound are highlighted along with radiology-pathology correlation with the appearance and characteristics of the histopathological specimen of these rare masses.

“…Fibroadenoma and phyllodes tumor should firstly be included in the differential diagnosis due to the black septum and lobulated shape of the mass shown on contrast-enhanced MRI. Duman L et al (10) reported that fibroadenoma tended to be homogeneously enhanced and had a hypointense internal septum, while in this case, even with a hypointense septum, the mass showed rapid heterogeneous enhancement which made a fibroadenoma unlikely. Although phyllode tumors are frequently lobulated in shape-this is similar to the MRI findings in this case-the internal cystic areas were detected in the former.…”

Inflammatory Myofibroblastoma of the Breast: A Case Report

Inflammatory myofibroblastic tumor (IMT) is a rare tumor with low-grade malignant risk mainly occurring in soft tissues and lungs, and it is extremely rare in the breast. Meanwhile, imaging findings of the tumor often present with non-specific features that lead to misdiagnosis and delayed treatment. Here, we report a case of inflammatory myofibroblastic tumor in the breast with the imaging findings of mammography, magnetic resonance imaging (MRI), and pathologic findings to improve the understanding of the disease. The patient was treated by surgical operation, and was followed up for 44 months, no local recurrence and distant metastasis.
