Immunohistochemical staining and FISH analysis results. Characteristic (A to C) phenotypical and (D) molecular features of angiomatoid fibrous histiocytoma. (A) Immunohistochemical view revealing diffusely positive staining for desmin (D33 clone; magnification, x20), (B) patchy staining for EMA (E29 clone; magnification, x20), and (C) CD68 (KP1 clone; magnification, x20). (D) FISH view revealing EWSR1 rearrangement. Original magnification, x63. The top right corner frame shows a 1.5X higher magnification. EMA, epithelial membrane antigen; FISH, fluorescence in situ hybridization.
