Adrenal cysts represent a rare condition (approximately 250 cases have been reported). We report two additional cases: the first involved a huge lesion removed surgically and thoroughly studied preoperatively; the second was an incidental autopsy finding. Detailed ultrastructural studies have been made of both cases. We think that the basic cell of origin of the cyst is an endothelial cell lining lymphatic channels. We speculate that the pseudocysts, which have been described as having a fibrous lining, probably were at one time also lymphendothelial but, perhaps due to trauma or repeated bleeding, the major portion of the endothelial lining became replaced by collagen. The primary and secondary cystic malignancies and cases of cysts due to parasites should be classified separately from the adrenal cysts of lymphendothelial origin which probably represent a benign tumor-like overgrowth.
肾上腺囊肿是一种罕见病症（据报道约有250例）。我们报告另外两例：第一例是通过手术切除的巨大病变，并在术前进行了全面研究；第二例是尸检偶然发现。对这两例均进行了详细的超微结构研究。我们认为囊肿的基本起源细胞是衬于淋巴管的内皮细胞。我们推测，曾被描述为具有纤维性内衬的假性囊肿，可能一度也是淋巴管内皮性的，但或许由于创伤或反复出血，内皮内衬的主要部分被胶原取代。原发性和继发性囊性恶性肿瘤以及寄生虫所致囊肿病例，应与可能代表良性肿瘤样过度生长的淋巴管内皮起源的肾上腺囊肿分开分类。
