It is well circumscribed and hence clinically mistaken as a Bartholin gland cyst.[11] Upon histologic examination, AMF is found to comprised plump spindled and epithelioid or plasmacytoid mesenchymal cells that are distinctly woven around blood vessels and set in a myxedematous, loosely collagenous stroma.[21] Intralesional adipose tissue and mast cells may be present.[11] Immunohistochemistry proves useful in discerning AMF, as the cells are desmin positive and generally negative for CD34 and smooth muscle actin.[2]. The gene discussed is DES; the disease is Bartholin duct cyst.
