a Entrapped pneumocytes. The entrapped lung tissue could be observed in the peripheral areas of the monophasic synovial sarcoma, resembling a biphasic synovial sarcoma. The entrapped pneumocytes are positive for thyroid transcription factor 1 (TTF-1) (a inset, 400×). b Tumor cells with “3+” positively nuclear TLE1 expression (×200). c FISH demonstrating a balanced rearrangement of the SS18 locus observed in the majority of the neoplastic cells (×1000). d In Case 9, the majority of tumor cells show two paired signals and one or multiple extra red signals, loss of green signal (arrow) (×1000)
