Myofibrosarcoma of the nasal bone.
Myofibrosarcoma is a recently recognized rare tumor that mainly occurs in adults. These tumors are composed of a collagenous stroma and pleomorphic stellate to spindle-shaped cells that resemble smooth muscle cells with eosinophilic cytoplasm and tapered nuclei. We present a case of myofibrosarcoma of the nasal bones in a 4-year-old girl who showed rapid enlargement of a painless glabellar swelling. Computed tomography and magnetic resonance imaging revealed an expanding solid mass with erosion of the surrounding nasal bones. After excision and histopathological examination, this tumor was identified as a myofibrosarcoma. This is the first report of such a tumor localized to the glabellar region. This case report contributes to better awareness of an extremely rare type of glabellar lesion in children.
