The cytologic features observed in fine needle aspiration smears and cell blocks from a retroperitoneal paraganglioma are described. The aspirate contained clusters of uniform cells of medium size, with ill-defined borders, round nuclei and evenly dispersed chromatin. An unusual feature was the presence of cytoplasmic pigment, which proved to be lipofuscin by histochemical staining and electron microscopy. The histologic and ultrastructural findings, as well as the results of histochemical and immunodiagnostic staining, are also presented.
描述了在腹膜后副神经节瘤的细针穿刺涂片和细胞块中观察到的细胞学特征。吸出物包含中等大小的均匀细胞簇，细胞边界不清，细胞核圆形，染色质均匀分布。一个不寻常的特征是存在细胞质色素，通过组织化学染色和电子显微镜检查证实为脂褐素。还展示了组织学和超微结构结果，以及组织化学和免疫诊断染色结果。
