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 the levator ani muscle into the pelvis. Biopsy revealed bland-appearing spindle-shaped cells positive for estrogen and progesterone receptors, consistent with an aggressive angiomyxoma. The mass was surgically excised without complication. To date, follow-up imaging has not demonstrated evidence of tumor recurrence.
