Pseudocysts are the most common nonfunctioning cystic adrenal lesions associated with symptoms. We have studied tissue from two patients with large adrenal pseudocysts in whom no antecedent cause could be documented. Immunohistochemical examination of these formaldehyde-fixed paraffin-embedded tissues with antibodies directed against the major proteins of the basement membrane (laminin and type IV collagen) revealed intense linear staining surrounding the cystic spaces and at the compressed adrenal cortical/pseudocyst interface. These findings lead us to conclude that these lesions are vascular in nature and, therefore, closely related to the previously recognized adrenal cysts of endothelial origin.
假性囊肿是最常见的与症状相关的无功能肾上腺囊性病变。我们研究了两名患有巨大肾上腺假性囊肿且无前驱病因记录的患者的组织。用针对基底膜主要蛋白（层粘连蛋白和IV型胶原）的抗体对这些甲醛固定石蜡包埋组织进行免疫组化检查，发现囊腔周围以及受压的肾上腺皮质/假性囊肿界面有强烈的线性染色。这些发现使我们得出结论，这些病变本质上是血管性的，因此与先前公认的内皮起源的肾上腺囊肿密切相关。
