Rare thoracic mass lesion - Myofibrobastoma
Indian Journal of Cancer, 2005
Mesenchymal soft tissue masses are uncommon tumours of the chest. Myofibroblastoma is a recently described entity consisting of cells with origin from the myoepethelial cell, mostly seen as benign well-circumscribed neoplasms of the breast tissue. Though usually classified as a benign lesion, rarely it can be multifocal and prone to recurrence.
Myofibroblastoma of the Breast
Journal of Breast Health, 2015
This study aimed presenting a case of a 64-year-old woman with a rare diagnosis of myofibroblastoma (MFB). MFB is one of the rare, benign, spindle-like stromal tumors arising from the connective tissue of the breast. MFBs are often confused with fibroadenomas and hamartomas because of their benign characteristic appearance on breast imaging and are diagnosed after excisional biopsies. Their differential diagnosis with malignant neoplasia of the breast is important because of their wide morphological spectrum. Our case also demonstrated a breast mass with benign imaging characteristics and a needle core biopsy revealing a benign, spindle-like stromal tumor. The pathological examination performed after the excision of the lump demonstrated a collagenous-/ fibrous-type MFB. This case report emphasizes the rare but important place of MFB variants of the breast in the differential diagnosis of breast mass.
An unusually large myofibroblastoma in a male breast: a case report
Journal of Medical Case Reports, 2008
Introduction: Myofibroblastoma of the breast is a rare benign stromal tumour seen predominantly in men. The gross appearance is that of a well-circumscribed nodule, characteristically small, seldom exceeding 3 cm. We present a case of an unusually large myofibroblastoma, which mimicked a malignant breast tumour.
Myofibroblastoma of male breast: report of three cases and review of the literature
European Radiology, 1997
We report three cases of male breast myofibroblastoma. This uncommon benign tumor arises from breast mesenchyma and is more frequently seen in adult men. Mammographic findings consist of a well-delimited, round to oval dense mass, variable in size but usually 1–4 cm in diameter. No microcalcifications were observed. Ultrasonography confirms the solid nature of the lesion, showing a well-circumscribed, homogeneous, hypoechoic mass, compressible with pressure. Although FNA cytology may support the diagnosis, surgical biopsy should be performed. Tumorectomy is the treatment of choice. To our knowledge, no more than 40 cases of breast myofibroblastoma have been reported. This is the first report in the literature which emphasizes the mammographic and ultrasonographic features of this tumor.
Myofibroblastoma of Male Breast: A Rare Case Report
2022
Myofibroblastoma (MFB) is an extremely rare benign tumour that can arise in various organs, but commonly in the breast. Myofibroblastoma of the breast is a rare benign stromal tumour seen predominantly in men in older age. The gross appearance is that of a well-circumscribed nodule, characteristically small, seldom exceeding 3 cm. Furthermore, myofibroblastoma can arise in extra mammary sites, along the milk-line.. Radiological imaging is nonspecific in MFB, and pathological examination of needle biopsy or surgically resected specimen is necessary for the diagnosis. Surgery is recommended and considered curative without additional treatment; however, patients should be followed-up. One case of MFB of the breast is described here since it is a very rare case and pre operative diagnosis is challenging.
Myofibroblastoma of the breast: two case reports and literature review
Journal of Surgical Case Reports
Myofibroblastoma (MFB) is a relatively rare tumor of the breast parenchyma, which belongs to the family of the ‘benign stromal tumor of the breast’. Two cases of MFB of the breast are described. Radiological imaging is nonspecific in MFB, and pathological examination of needle biopsy or surgically resected specimen is necessary for the diagnosis. Surgery is recommended and considered curative without additional treatment; however, patients should be followed-up.
Breast myofibroblastoma in a young woman: a case report
Annali italiani di chirurgia, 2013
Myofibroblastoma (MFB) is an uncommon benign mesenchymal tumor that may arise in several organs and tissue. Although most of reported cases were located in the breast, it is extremely rare, representing less than 1% of breast tumor. MFB has predominantly seen in elderly men, but some cases have been described in menopausal women. This lesion is a stromal tumor which has many morphologic variants including cellular, collagenized, epithelioid, palisaded, lipomatous, hemangiopericytoma-like, and infiltrant features. Even if its incidence has recently increased due to the mammary screening, only few cases have been reported in Literature and even less in young women. Physical examination discloses a solitary, unilateral, painless, freely movable, usual firm in consistency, non-tender nodule. Imaging investigations usually are not specific to establish the right diagnosis. Furthermore, findings from Fine-Needle Aspiration (FNA) may be confusing and nonspecific, making diagnosis of MFB po...

H Abstract: We present the cytologic, histologic, immunohistochemical, and ultrastructural features of two cases of myofibroblastoma with different cellularity, one paucicellular the other hypercellular. Fine-needle aspiration suggested the diagnosis in the case of the hypercellular tumor of the breast and pointed out the benign nature of the paucicellular case, arising in the breast of a young woman. Immunohistochemistry, showed smooth muscle-specific actin, vimentin, and desmin positivity consistent with myofibroblastic differentiation, in both cases. The positivity of both tumors to CD34 suggests that they may be related to the so-called solitary fibrous tumor. In addition, there was strong progesterone-and weak estrogen-receptor positivity ion the hypercellular case, a novel finding in these tumors, with possible histogenetic implications. Ultrastructural findings in the first case were consistent with the myofibroblastic origin of the tumor.
