Annulate lamellae have been found in a primitive neuroectodermal tumor, a metastatic cerebellar tumor, a testicular seminoma, a retinoblastoma and three melanomas. These annulate lamellae are arranged in stacked parallel arrays in the cytoplasm of tumor cells. The number of annulate lamellae observed to comprise a single stack varies from 2--4 in the seminoma tumor to 5--18 in the cerebellar tumor. Although the functional significance of annulate lamallae is still unknown, in many instances they have been found to be continuous with rough-surfaced cisternae of the endoplasmic reticulum and ribosomes have been demonstrated on the surface of annulate lamellae. This may suggest that annulate lamellae participate in protein synthesis.
在一种原始神经外胚层肿瘤、一种转移性小脑肿瘤、一种睾丸精原细胞瘤、一种视网膜母细胞瘤以及三种黑色素瘤中均发现了环状片层。这些环状片层在肿瘤细胞的细胞质中呈平行堆叠排列。观察到构成单个堆叠的环状片层数量，在精原细胞瘤中为2 - 4个，在小脑肿瘤中为5 - 18个。尽管环状片层的功能意义尚不清楚，但在许多情况下，已发现它们与内质网的糙面池相连，并且在环状片层表面已证实有核糖体存在。这可能表明环状片层参与蛋白质合成。
