Aggressive angiomyxoma of the vulva: An unusual, deceptive and recurrence‐prone tumour with evidence of estrogen receptor expression

Positive staining for estrogen receptors is reported in a new case of aggressive angiomyxoma of the vulva. Clinical, light- and electron microscopic features as well as immunohistochemical reactions in this case are compared with the 28 earlier published cases, and the main differential diagnosis, angiomyofibroblastoma of the vulva, is discussed.
