Mammary-type myofibroblastoma


Benign myofibroblastic tumor with hyalinized collagenous stroma

Clinical Features

  • Incidence

    Extra-mammary location of a myofibroblastoma is rare (about 160 cases have been reported in English literature).

  • Age

    The age ranges from 30 to 85 years with a median age of 55 years.

  • Sex

    Slight male predominance (65%).

  • Site

    Initially described in the breast, it usually arises in the inguinal/groin region or along milk line. It is also observed in the abdominal wall, buttock, back, and vaginal wall. The tumor is usually found in the subcutis, but may be deeper. Localization of the tumor in male genital organs is very rare, but is described in the scrotal sac, spermatic cord, paratesticular region, prostate, and seminal vesicles.
