Malignant transformation of axillary lipomatous masses in Madelung’s disease. A) At low magnification vascular density was evident with abundance of vessels with characteristic arborizing shapes (H&E; original magnification: 200x). B) Lipoblasts were frequently observed at high power magnification (insets), together with the typical delicate vascular network (not shown). In the lower right inset an atypical mitosis is shown. These findings indicated a well differentiated liposarcoma (H&E; original magnification: 400x)
