Study of a human abdominal paraganglioma under electron microscopy revealed an unusual cytoplasmic inclusion appearing as a hollow cylinder made up of one or several concentric lamellae surrounded by single or aggregated granules. Cross sections of the lamellar element show a discontinuous juxtaposition of particles. It is moderately dense and is bordered by 140--to 250-A granules of sure ribosomal nature. The inclusion is closely connected to the rough endoplasmic reticulum. The origin and significance of this complex are discussed.

对一例人类腹部副神经节瘤进行电子显微镜研究发现，一种不寻常的胞质内含物，呈空心圆柱体状，由一层或几层同心薄片组成，周围有单个或聚集的颗粒。薄片成分的横截面显示颗粒呈不连续并列。它密度适中，边界为140至250埃的颗粒，确定具有核糖体性质。该内含物与粗面内质网紧密相连。讨论了这种复合体的起源和意义。
