Clinicopathological and radiological characterization of myofibroblastoma of breast: A single institutional case review

A Large Myofibroblastoma of the Breast in a Premenopausal Woman: A Case Report and Review of the Literature

“…In the present reported case, the tumor was encapsulated with a thin well-delineated capsule that was easily separated from the mass. The average size of these tumors ranges between 1 and 3.7 cm [13], and large MFBs of 10 cm and above have been rarely reported [14]. The tumor in our case has grown to a 10-cm mass.…”

Radiation‐induced myofibroblastoma within the nasal sinus requiring maxillectomy and ethmoidectomy: A case report and literature review

“…Radiation‐induced myofibroblastomas have been reported in the literature, most commonly concerning the breast. 14 , 15 An instance of radiation‐induced, low‐grade myofibroblastic sarcoma in the maxillary sinus was reported with a patient receiving radiotherapy for nasopharyngeal carcinoma, with the median radiation dose at the cancer site being 66 Gy during previous radiotherapy. 16 The reported latency in this case was approximately 60 years, which is a larger time duration when compared with reported solid tumor induction times 10 and for the case of reported myofibroblastic sarcoma in the maxillary sinus found in literature.…”

Epithelioid myofibroblastoma of the breast: A case report and review of the literature

“…The differential diagnoses of breast MFB include other spindle cell tumours such as pseudo-angiomatous stromal hyperplasia (PASH), fibromatosis, nodular fasciitis (NF), solitary fibrous tumour (SFT), spindle cell lipoma, leiomyoma, and metaplastic spindle cell carcinoma [21] . Inflammatory myofibroblastic tumour (IMT) should also be raised as a differential diagnosis [22] .…”

“…Despite nuclear atypia, close examination would demonstrate that hyperchromasia, higher mitotic count, coarsely condensed chromatins, conspicuous nucleoli, invasion (stromal reaction), and necrosis are not observed. In addition, the epithelioid variant of MFB may mimic invasive lobular carcinoma, especially when the tumour cells are associated with nuclear atypia [7] , [21] , [30] . The epithelioid subtype of MFB is defined that the more than half of the tumour cells appear as epithelioid cells [7] .…”
