Immunohistochemical studies were performed to categorize the spindle cells. These cells are positive for HMB-45 (b), smooth muscle actin (c), and show membranous and cytoplasmic staining with beta catenin (d). This immunophenotype is consistent with LAM (a hematoxylin and eosin, original magnification 200X; b HMB-45, original magnification 200X; c smooth muscle actin, original magnification 200X; d beta catenin, original magnification 200X)
