Mammary-type myofibroblastoma [14] Myofibrobastoma, also termed myofibroblastoma of soft tissues, is a mammary-type myofibroblastoma that occurs in non-mammary tissues [15] and may be as much as 10-fold more common than the mammary type. [14] Calcifying aponeurotic fibroma, also termed aponeurotic fibroma [16]
Medical imaging may suggest but cannot prove that a tumor is MFB. Mammography, computed tomography scans, and magnetic resonance imaging of mammary [1] [12] and extramammary [1] [13] MFB typically show well-defined and well-circumscribed tumors which in almost all cases have no calcifications; these results suggest that the tumor is not malignant but do not indicate which type it might be.
Currently, however, inflammatory pseudotumor designates a large and heterogeneous group of soft tissue tumors that includes inflammatory myofibroblastic tumor, plasma cell granuloma, xanthomatous pseudotumor, solitary mast cell granuloma, inflammatory fibrosarcoma, [4] pseudosarcomatous myofibroblastic proliferation, myofibroblastoma ...
Mayo Clinic is a nonprofit hospital system with campuses in Rochester, Minnesota; Scottsdale and Phoenix, Arizona; and Jacksonville, Florida. [22] [23] Mayo Clinic employs 76,000 people, including more than 7,300 physicians and clinical residents and over 66,000 allied health staff, as of 2022. [5]
The Mayo Clinic Cancer Center is one of the oldest NCI-designated cancer centers in the United States, having first been designated in 1973. [3] The main location of the Mayo Clinic is in Rochester, MN. Campuses in Arizona and Florida opened later and became part of the Mayo Clinic Cancer Center in 2003. [4] [5]
Intranodal palisaded myofibroblastoma (IPM) is a rare primary tumour of lymph nodes, that classically presents as an inguinal mass. [ 1 ] It afflicts predominantly males of middle age.
Angiomyofibroblastoma is an uncommon benign mesenchymal tumor. It occurs mostly in the vulvovaginal area of women, but can also be observed in men. The World Health Organization, 2020, reclassified these tumors as a specific type of tumor in the category of fibroblastic and myofibroblastic tumors.
Myofibroblasts are contractile web-like fusiform cells that are identifiable by their expression of α-smooth muscle actin within their cytoplasmic stress fibers. [1]In the gastrointestinal and genitourinary tracts, myofibroblasts are found subepithelially in mucosal surfaces.
