robbins 當中對於這個的敘述為:
"The most common benign tumor is a spherical, small (3 to 4 cm), discrete 'hamartoma' that often shows up as a so-called coin lesion on chest radiographs."
此外,亦有提及其形態:
"It consists mainly of mature cartilage, but this is often admixed with fat, fibrous tissue, and blood vessels in various proportions.成熟軟骨構成,並且混雜其他脂肪、纖維組織、血管等
ㅤㅤ
- 肺臟最常見良性腫瘤 = Hamartoma(錯構瘤)。
- 常呈現 coin lesion(孤立性肺結節)。
- 組成以 成熟軟骨(cartilage) 為主,混有脂肪、纖維組織及血管。
- Robbins 進一步指出肺 hamartoma 具有 clonal cytogenetic abnormalities,因此現代觀念認為它其實是真正的良性腫瘤(benign neoplasm),而不只是單純發育異常。
