A case report and literature review: post-traumatic mammary myofibroblastoma

Hadi Abdullah Alaskar, Ahmed Mohammed AlMuhsin, Mirza Faraz Saeed, Amro Salem


Mammary myofibroblastoma is a rare benign tumor of the breast, with a higher incidence in elderly age group. It is diagnosed via radiologic and histologic findings, as clinical findings share the same presentation with other, more common, benign breast pathologies. Surgical excision is the only treatment modality used to treat this tumor. We report the case of a 56-years-old-male, who presented with the complaint of left-sided chest swelling for 1 year following a minor trauma to the chest. Ultrasonographic imaging of the mass was the initial investigation and it revealed a well-defined hypoechoic lesion, excisional biopsy was done, followed by histopathological analysis of the mass, which gave the diagnosis of mammary myofibroblastoma. The aim of this case-report is to further study and characterize this rare lesion and its relationship to previous minor or major trauma and other risk factors, in addition, a proper diagnosis should be taken when encountering a similar mass as it mimics many benign and malignant tumors, furthermore a follow up plan should be established to assess the rate of possible recurrence.
