Abstract

Aggressive angiomyxoma (AAM) is a rare, benign tumor. It usually involves the connective tissue of the perineal regions in women of reproductive age. In this report, we present a case of AAM in a 66-year-old female, which presented itself as a retrovesical tumor on pelvic magnetic resonance imaging and caused lower urinary tract symptoms. The tumor was resected en bloc and the patient's voiding symptoms disappeared.

  Fig. 1 (A, B) Transvaginal ultrasonography showing a huge tumor compressing the urinary bladder. (C) T1-weighted magnetic resonance image (MRI) showing a mass with low signal intensity posterior to the urinary bladder. (D) T2-weighted sagittal MRI showing a mass with intermediate signal intensity.

  Fig. 2 The gross findings are a rather well-circumscribed gray-white mass with a soft, smooth and elastic surface.

• 

  Fig. 3 Pathologic findings show dispersed spindle-shaped cells and thick-walled blood vessels with a myxoid stroma [(A) ×100, (B) ×400].

  Fig. 4 Immunohistochemical analyses show positive results for (A) estrogen receptor, (B) desmin, and (C) progesterone receptor.
