Previous light and electron microscopic examinations of sclerosing hemangiomas of the lung have raised questions regarding their varying microscopic patterns and cells of origin. We describe two additional cases: one studied by light microscopy revealed the classic pattern of a sclerosing hemangioma of endothelial origin, and a second, studied by combined light and electron microscopy, had incomplete small peripheral airways and occasional alveolar-like spaces derived from epithelial and mesothelial cells. It is concluded that sclerosing hemangiomas of the lung may sometimes consist of admixtures of tissues of epithelial, mesothelial, and endothelial cell origins and thus represent a form of pulmonary hamartoma.
以往对肺硬化性血管瘤的光镜和电镜检查对其不同的微观模式和起源细胞提出了疑问。我们描述另外两例病例：一例经光镜检查显示为典型的内皮起源的硬化性血管瘤模式，另一例经光镜和电镜联合检查，有不完全的小周边气道以及偶尔由上皮细胞和间皮细胞衍生的肺泡样间隙。结论是，肺硬化性血管瘤有时可能由上皮细胞、间皮细胞和内皮细胞起源的组织混合组成，因此代表一种肺错构瘤形式。
