Mammary-type myofibroblastoma

Mammary-type Myofibroblastoma is a rare, benign tumor that can occur in both men and women. It is most commonly found in the mammary gland, but can also occur in other parts of the body. The tumor is composed of myofibroblasts, a type of cell that is involved in wound healing and tissue repair.

Clinical Features

Patients with mammary-type myofibroblastoma typically present with a painless, slow-growing mass. The tumor can occur at any age, but is most common in middle-aged and older adults. It is equally common in men and women.

Pathology

Under the microscope, mammary-type myofibroblastoma is composed of spindle-shaped myofibroblasts arranged in a fascicular or storiform pattern. The tumor cells have eosinophilic cytoplasm and elongated nuclei. There is usually a moderate amount of collagenous stroma.

Diagnosis

The diagnosis of mammary-type myofibroblastoma is made by biopsy of the tumor. The pathologist will examine the tissue under a microscope to confirm the diagnosis.

Treatment

The treatment for mammary-type myofibroblastoma is surgical removal of the tumor. In most cases, the tumor is completely removed and does not recur. However, in some cases, the tumor may recur if it is not completely removed.

Prognosis

The prognosis for patients with mammary-type myofibroblastoma is generally good. The tumor is benign and does not spread to other parts of the body. However, the tumor can recur if it is not completely removed.
