Ectopic tissues rarely occur in the lung. They include endometriosis, neurological tissue, thyroid, pancreas, and adrenal. Choristomas are very rare developmental anomalies derived from these ectopic tissues. They develop as a mass composed of histologically normal tissues that are heterotopic in the lung. Various intrapulmonary neoplasms also rarely develop from ectopic tissues. They include malignant melanoma, thymoma, meningioma, glomus tumor, germ cell neoplasms (choriocarcinoma and teratoma), and ependymoma. The clinicopathological features of these unusual pulmonary neoplasms are discussed.
异位组织很少出现在肺部。它们包括子宫内膜异位症、神经组织、甲状腺、胰腺和肾上腺。迷离瘤是源自这些异位组织的非常罕见的发育异常。它们发展为肺内组织学上正常但异位的组织构成的肿块。各种肺内肿瘤也很少由异位组织发展而来。它们包括恶性黑色素瘤、胸腺瘤、脑膜瘤、血管球瘤、生殖细胞肿瘤（绒毛膜癌和畸胎瘤）和室管膜瘤。本文讨论了这些不寻常的肺肿瘤的临床病理特征。
