Clinical and immunohistochemical data of the two cases.

	Age (yr)/Sex	Tumor size (cm)	Component	Bcl-2	CK	EMA	Vimentin	CD99
Case  1	18/F	7 × 7 × 6	Epithelial	Focal (+)	+	+	+	Focal (+)

CK = cytokeratin (monoclonal, 1 : 50; Dako); EMA = epithelial membrane antigen (monoclonal, 1 : 200; Dako); Vimentin = vimentin (monoclonal, 1 : 200; Dako); CD99 = CD99 (monoclonal, 1 : 50; Dako).
