Aggressive angiomyxoma is a rare tumour type with a predilection for the female pelvis, high rates of estrogen and progesterone receptor positivity and local recurrence. A retrospective chart review of patients with aggressive angiomyxoma treated at 2 cancer centres is presented.Nine patients were identified with a mean age of 41. Five patients had deeply invasive tumours that were difficult to surgically resect. Four patients had pedunculated tumours with less complex resections. In only two cases was aggressive angiomyxoma considered before resection: one due to classic magnetic resonance imaging findings and one with a preoperative biopsy. Four patients had positive margins after resection, with only one having persistent disease. Two patients were treated with gonadotropin-releasing hormone (GnRH) agonists resulting in tumour regression in one and no recurrence in the other. In this case series, aggressive angiomyxoma presented in deeply invasive and pedunculated forms. Previously reported high rates of recurrence were not observed in this group, perhaps secondary to easier resection in the pedunculated forms. GnRH agonists were successfully used as adjuncts to surgery. Evidence in this case series could be used to provide tailored treatment to patients with aggressive angiomyxoma.
