The World Health Organization in 2020 classified mammary type myofibroblastoma tumors and myofibroblastoma tumors (i.e. extramammary myofibroblastic tumors) as separate tumor forms within the category of fibroblastic and myofibroblastic tumors. [8] Mammary MFB likely represents less than 1% of all breast tumors. [9]
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]
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 ...
Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes.
Other names associated with plasma cell granulomas are inflammatory myofibroblastic tumor, inflammatory myofibrohistiocytic tumor, benign myofibroblastoma, pseudosarcoma, fibrous histocytoma, fibroxanthoma, xanthomatous pseudotumor, xanthogranuloma, myxoid hamartoma, and lymphoid hamartoma.

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.
Low-grade myofibroblastic sarcoma (LGMS) is a subtype of the malignant sarcomas. [1] As it is currently recognized, LGMS was first described as a rare, atypical myofibroblastic tumor (i.e. a tumor consisting of cells with the microscopic features of fibroblasts and smooth muscle cells) by Mentzel et al. in 1998.
