Deep (aggressive) angiomyxoma of the vagina misdiagnosed as Gartner cyst: A case report

Abstract

Introduction and importance: Aggressive angiomyxoma is a rare soft tissue tumor. Aggressive angiomyxoma is a slow-growing vulvovaginal mesenchymal neoplasm with a marked tendency for local recurrence, but with a low tendency to metastasize. As it has a predilection for the pelvic and perineal regions, Aggressive angiomyxoma is often misdiagnosed. This case report documented rare case of misdiagnosed Aggressive Angiomyxoma as Gartner duct cyst.

Presentation of case: This article report a case of 31 year old women who complained mass came out from vagina without any urinary symptom and trauma. Physical examination and ultrasound finding suggested that the mass was Gartner Duct cyst. Management in this case was excision of the vaginal cyst. Histopathology examination revealed Deep (aggressive) angiomyxoma.

Discussion: The rarity of Deep (Aggressive) Angiomyxoma makes the preoperative diagnosis fairly difficult. Aggressive angiomyxoma is often misdiagnosed as it may have similar clinical presentation to common lesions such as Bartholin cyst or prolapse vaginal wall, Gartner cyst or levator hernia. Aggressive Angiomyxoma should be considered as differential diagnosis in patient with vaginal cyst.

Conclusion: Aggressive Angiomyxoma is rare condition. Preoperative diagnosis and management are challenging. Long term follow op and evaluation should be done due to high rate of recurrence.
