adrenal cytomegaly是Beckwith-Wiedemann综合症的特征性成分……。主要在11P15区域内的生长调节基因失功能,导致正常生长失控,并增加某些肿瘤的发生率。 在这种疾病中,肾上腺可增大,同时重量可增至16 g。奇怪的是肾上腺的嗜铬组织可能增生或不适时的成熟了。还可能有肾和胰腺的内脏肿大,有些婴儿还发展严重的新生儿低血糖,可致死……
同时请参看一下Dr.quhong对肾上腺发育的描述。

There are old hemorrhage, multinucleated giant cell reaction, calcification and recent hemorrhagic infarction in the adrenal mass containing residual adrenal cortex. I do not think this is neuroblastoma, ganglioneuroblastoma, pheochromocytoma or adrenal cortical adenoma. Figures 9 and 10 suggest nephrogenic adenoma, but the patient's young age, anatomic location and other features do not support this possibility. Like some who have commended, I am not certain this is a neoplasm. I don't think this is Rosai-Dorfman disease.
肾上腺肿物,见残留的肾上腺皮质,有陈旧出血、多核巨细胞反应、钙化和新鲜出血性梗死,我认为不是神经母细胞瘤、节细胞神经母细胞瘤、嗜铬细胞瘤或肾上腺皮质腺瘤。图9、10提示肾源性腺瘤样,但患者年幼、解剖部位和其它特征不支持这种可能性。象前面一些网友提到的,我不能确定是肿瘤性病变。也不考虑Rosai-Dorfman 病。

Very interesting case. I have to admit that I don't do autopsy and pediatric pathology in our Hospital, one thing I still remember during my residency is that newborn adrenal gland is quite common to have zonal necrosis in the cortex, and the cells will eventually re-populate the cortex. Based on the pictures, I favor that this is not a neoplastic process. I will try to show the pictures to some experts and see what they are going to say. Thanks!
非常有意义的病例。我必须承认,在我们医院我不做尸检和儿科病理。我仍然记得,我做住院医生时新生儿肾上腺很常见皮质区坏死,细胞最再次走入皮质。根据这些,我倾向这不是肿瘤性病变。我会试着上传一些图给专家们看看,它们会说明什么。谢谢!(abin译)
