Aggressive angiomyxoma of the thigh: A case report and review of the literature.

In this study, we report a case of aggressive angiomyxoma (AAM) of the thigh in a 43-year-old female patient. Ultrasonography revealed a 6.1×3.7×5.3 cm solid mass in the right thigh with well-demarcated borders and a heterogeneous echotexture. Color Doppler ultrasonography (CDUS) revealed weak blood flow in the mass with peripheral and central avascularity. Computed tomography (CT) of the thigh revealed a homogeneous low-density mass under the spatium intermusculare of the quadriceps femoris. The mass was diagnosed as AAM by histopathological examination following complete excision around the adventitia of the tumor. At 18 months follow-up, there was no recurrence. In conclusion, this case is noteworthy as it involves AAM of the thigh, which is a rare tumor.
