为了详细阐明毛细胞黏液样的形态学谱以及毛细胞黏液样星形细胞瘤(PMA)和毛细胞星形细胞瘤(PA)之间的关联特征,作者回顾了84例具有毛细胞黏液样特征的儿科星形细胞瘤,其中42例具有PMA和PA的共同特征,并称之为“中间型”毛细胞黏液样肿瘤。由于这些中间型肿瘤细胞具有较丰富的胞质、原纤维背景、微囊和厚壁血管,组织学更像是PA,而不像是经典的PMA。在复发性病例中,PMA和中 To clarify the morphological features of hairy myxoid and the correlation between hairy cell astrocytoma (PMA) and hairy cell astrocytoma (PA), the authors reviewed 84 hairy myxoid-like features Of the pediatric astrocytomas, 42 of which had common features of PMA and PA and were referred to as “” intermediate "hairy myxoid tumors. Because these intermediate tumor cells have a richer cytoplasm, fibril background, microcapsules and thick-walled blood vessels, histology is more like PA, unlike the classic PMA. In recurrent cases, PMA and MED
