Aggressive angiomyxoma is a rare mesenchymal neoplasm of the soft parts of the pelvis. It is a benign lesion with a high incidence of recurrence that presents mainly in women in the third or fourth decades of life, and particularly affects the pelvis and perineum.1 The cell of origin is the myofibroblast.2 We describe a 38-year-old woman with a tumor of this type and a mass in the right cardiac chambers on imaging study. Following surgery, this was shown to be part of the tumor growth that had reached the right atrium through the inferior vena cava. The patient consulted for abdominal swelling of several months’ evolution that was associated with abdominal and lumbar pain, as well as a feeling of dysthermia and vomiting. An abdominal mass was palpated in the emergency room.
