NTRK-REARRANGED SARCOMA Figure 3-63 NTRK-REARRANGED SARCOMA A: On low-power magnification, the tumor may have a variable appearance, ranging from patternless to areas with somewhat fascicular growth. B,C: The neoplastic spindle cells often surround and envelop native endocervical glands (B) and sometimes produce intraglandular polypoid projections (C). D: The tumor cell population can show variable atypia. In this example, there is only mild nuclear pleomorphism; note the prominent vascular hyalinization. E: The neoplastic cells are usually positive for S-100 protein, although the extent and intensity can be variable. F: Pan-TRK is typically diffusely positive, although this result is not specific.
