Sonographic findings in superficial angiomyxoma of the vulva in a perimenopausal female

: Superficial angiomyxoma (SAM) is an extremely rare soft tissue tumor. It is especially rare in the vulva, with only a few such cases reported in the medical literature. Here, we report a case of SAM of the vulva that was initially suspected to be a Bartholin gland cyst. The patient underwent local excision of the vulvar cyst under lumbar anesthesia. Clinical manifestations and B-scan ultrasonographic features are similar between SAM and cysts. Echoes in the mass are uneven and exhibit low echoes and punctate hyperechoic floating. Thus, increasing sonographers' awareness of the high-frequency ultrasonography findings associated with this rare tumor could broaden their knowledge base.
