Bilateral Bizarre Vulvar Swellings in a Teenager: A very rare Entity of Aggressive Angiomyxoma
Background: Aggressive angiomyxoma (AA) is a rare mesenchymal neoplasm that commonly occurs in perineal region of females. Case Report: A 17 years female presents with bilateral bizarre vulvar swellings, gradually increasing in size for 2 years, painful for 1 week. Sonographic evaluation revealed bilateral well-defined hypoechoic lesions with internal vascularity and cystic areas. Magnetic resonance imaging (MRI) demonstrated these lesions to be iso-intense to skeletal muscles on T1-weighted images (T1WI) and hyperintense on T2-weighted images (T2WI). These were surgically excised and sent for histopathology that confirmed these lesions to be AA. Discussion: AA is an uncommon neoplasm of mesenchymal origin that arises mainly in the perineal soft tissue of adults. It occurs predominantly in females with a peak incidence in fourth decade. [1] In our case the patient was a teenager. In females it may present as a vulvar nodule, polyp or may even be mistaken for a Bartholin’s or labial cyst. In males it involves analogous sites including inguino-scrotal region. [4] Most of the reported cases include solitary unilateral lesions. Conclusion: Our case is unique because the patient was in her teenage and presented with bilateral vulvar angiomyxomas that showed internal vessels on colour doppler imaging.
