PLIN1 was absent from non-lipomatous sarcomas (0/179), PLIN2 expressed in all fibrosarcomas (18/18), Ewing's sarcomas (17/17), epithelioid sarcomas (8/8), and in most rhabdomyosarcomas (17/22), leiomyosarcomas (31/42), dermatofibrosarcoma protuberans (23/38), and undifferentiated sarcomas (33/34). This evidence concerns the gene PLIN2 and epithelioid sarcoma.
