We report the incidence and features of small cystic and noncystic noninflammatory renal lesions found in a series of 500 unselected necropsies performed for forensic reasons in a Portuguese population. A total of 997 kidneys was sectioned serially in 0.2 cm. sections. There were 1,256 lesions (the large majority being less than 1 cm.) found in 380 examined organs belonging to 265 cases. A total of 1,105 cystic lesions was observed in 195 (39 per cent) specimens, 108 medullary fibrous nodules in 89 (17.8 per cent), 29 cortical adenomas in 20 (4 per cent), 5 leiomyomas in 5 (1 per cent), 4 lipomas in 4 (0.8 per cent), 2 fibromyolipomas in 2 (0.4 per cent) and 3 fibromas of the capsule in 3 (0.6 per cent). Cystic lesions showed an increase in number with patient age, which does not occur with medullary fibrous nodules. Cortical adenomas were most frequent at the fifth and sixth decades of life. The risk of malignancy, with the possible exception of some of the cortical adenomas, is believed to be small.
我们报告了在葡萄牙人群中因法医原因进行的500例未经挑选的尸检中发现的小囊性和非囊性非炎性肾病变的发生率及特征。总共997个肾脏被连续切成0.2厘米厚的切片。在属于265例患者的380个检查器官中发现了1256个病变（绝大多数小于1厘米）。在195个（39%）标本中观察到总共1105个囊性病变，在89个（17.8%）标本中发现108个髓质纤维结节，在20个（4%）标本中发现29个皮质腺瘤，在5个（1%）标本中发现5个平滑肌瘤，在4个（0.8%）标本中发现4个脂肪瘤，在2个（0.4%）标本中发现2个纤维平滑肌脂肪瘤，在3个（0.6%）标本中发现3个包膜纤维瘤。囊性病变的数量随患者年龄增加，而髓质纤维结节则不然。皮质腺瘤在第五和第六个十年最为常见。除了一些皮质腺瘤外，恶性风险被认为很小。
