银鲫精母细胞型精原细胞瘤的病理学观察

PATHOLOGICAL FEATURES OF SPERMATOCYTIC SEMINOMA IN CARASSIUS GIBELIO

  • 摘要: 自银鲫(Carassius gibelio)中发现了一例自发性精母细胞型精原细胞瘤, 详细描述了该肿瘤的组织病理和超微结构。在组织学上, 该肿瘤具有薄膜包被、扩张性生长, 具有高度细胞性和弥漫性结缔组织, 伴有淋巴细胞浸润。透射电镜显示, 该肿瘤显著的特征是含有未分化的精母细胞, 且支撑细胞稀少。对比正常银鲫的精巢组织结构, 排除了其他肿瘤类型, 最终将该肿瘤鉴定为精母细胞型精原细胞瘤。系在低等脊椎动物中首次发现具有淋巴细胞浸润的精母细胞型精原细胞瘤, 丰富了鱼类性腺肿瘤的基础资料, 也为构建人类精母细胞型精原细胞瘤动物模型提供了依据。

     

    Abstract: This study described pathological features of a spontaneous spermatocytic seminoma in gibel carp Carassius gibelio. Histologically, the neoplasm founded in the abdomen was encapsulated invasive spermatocytic seminoma with an inconspicuous lobular architecture and diffuse fibro-connective septa with lymphocytic infiltration. For its ultrastructure, undifferentiated spermatocytes and fewer supporting cells were the unique features of the neoplasm. Compared with the histological features of normal testis of gibel carp, this neoplasm was identified as a spermatocytic seminoma. The first report of spermatocytic seminoma with lymphocytic infiltration in fish may contribute to the establishment of fish model of spermatocytic seminoma.
