'''Aggressive angiomyxoma''', also '''deep aggressive angiomyxoma''', is a rare benign lesion, typically of the [[vulva]], with a locally aggressive behaviour. | |||
==General== | |||
*Classically a [[vulva]]r mass or (less commonly) a [[scrotum|scrotal]] mass. | |||

*Benign - no metastatic potential. | |||
*"Aggressive" as it has a high recurrance. | |||
==Gross== | |||
*Poorly circumscribed. | |||
*"Rubbery" or "gelatinous". | |||
