Vulval Aggressive Angiomyxoma in a 19 year teenager: a case report

Abstract

Background: Aggressive Angiomyxoma is a benign, slowly growing, locally aggressive and recurrent tumour that occurs in the pelvic-perineal region of females in their reproductive years. It presents as a painless, soft, gelatinous mass and metastasizes rarely. Suspicion can be made based on clinical examination and radiological imaging but final diagnosis is confirmed only after histopathology and immunohistochemistry. The choice of treatment is surgical wide local excision. Case presentation: We hereby present a case of a 19-year, unmarried lady, with a body mass index of 21 kg/m2, who presented with a chief complaint of painless mass in left vulva which progressively increased in size in the past one year. Clinical examination revealed a large, cauliflower like, exophytic mass of 10 cm × 10 cm size. Radiological imaging confirmed involvement of lymph nodes. Wide local excision with adequate tumour free margin and depth was used as a treatment modality. The diagnosis was confirmed via histopathological examination of the excised specimen. There is no recurrence in the patient up to date. Conclusion: Aggressive Angiomyxoma is a rare tumour and it is most often misdiagnosed. This report highlights the importance of considering Aggressive Angiomyxoma as a differential diagnosis of vulval masses and the two-step surgical approach for its treatment in low resource setting.
