Aggressive angiomyxoma of left buttock

Abstract

Aggressive angiomyxoma (AA) is a rare mesenchymal tumour that is characterised by increased incidence in women compared with men, local invasion to the surrounding tissue and high recurrence rate. A premenopausal woman presented to clinic with pelvic pressure, intermittent tingling in the thigh and pressure emptying the bladder. CT scan, vaginal and gluteal biopsies, and MRI scan were performed to conclude a final diagnosis of AA. The patient underwent complete resection of the mass. The mass tested positive for oestrogen receptor and progesterone receptor. The patient received leuprolide postoperatively to prevent recurrence. AA should be considered as a differential diagnosis for a pelvic and perineal mass. Patients should be warned of high recurrence rate, necessity of surgical removal and long-term hormonal treatment.

Malignant tumour in pregnancy: Ewing-like sarcoma of the gluteal region

“…This tumour has aggressive behaviour with local invasion of the surrounding tissue and a high recurrence rate. Histological examination is fundamental to reach the correct diagnosis of this mass 6. The analysis of the tumour revealed a round-cell mesenchymal neoplasm immunohistochemically compatible with an Ewing family sarcoma.…”
