Tumor miofibroblástico de origen ovárico: comportamiento agresivo y fatal

Myofibroblastic tumors are infrequent, particularly in extrapulmonary and genital sites, with few cases described within the ovaries in the international literature. The diagnosis, based on histopathology is always a challenge for the pathologist, due to the heterogeneity of the immunohistochemistry. Their behaviour is mostly benign, although some subtypes may recur, be locally aggressive, and have potential to metastasise. Prognostic factors for malignant potential have been described, unfortunately without predicting the biological behaviour in all cases. The mainstay of treatment is surgery, taking into account an appropriate extension to provide negative surgical margins, thus decreasing the risk of recurrence.
