A 47-year-old female presented to clinic with a 5-year history of a left buttock mass. The patient's hemoglobin was low (9.7 g/dL); laboratory analysis was otherwise unremarkable. Ultrasound of the left gluteal region demonstrated a heterogeneous vascular solid lesion. Magnetic resonance and computed tomography imaging showed an enhancing mass extending from the left ischioanal fossa through th...

Angiomyxoma is a rare, slow-growing myxoid neoplasm that occurs almost exclusively in the genital, perineal, and pelvic regions of adult women. It mostly occurs during the reproductive years. It has propensity for local recurrence [1–4].

The tumor was resected by a transurethral procedure and a pathological examination of...

Aggressive angiomyxoma (AA) is a rare mesenchymal tumor that usually occurs in the pelvis and perineum of young females. AA can simulate Bartholin's gland cyst, abscess, lipoma, simple labial cyst, or other pelvic soft tissue tumors. Cross-sectional imaging, particularly magnetic resonance imaging (MRI), plays an essential role in the diagnosis and management of AA. We report a case of AA in a ...
