[Myxoid uterine leiomyoma with focal lymphangioma-like pattern]

Myxoid leiomyomas of the uterus are uncommon. They are characterised by a myxoid stroma, no mitotic activity and a myogenic phenotype. We present a case with focal lymphangioma-like pattern. The solid compartiment showed positive immunoreactivity with muscular markers and but no CD 34-immunostaining. Contrary, the endothelial-like cells of the cystic part were positive with antibodies against CD 34, CD 31 and factor VIII, indicating vascular differentiation. The lack of infiltrative growth patterns excluded myxoid leiomyosarcoma as the major differenzial diagnosis.
