Clear cell tumor of the lung is a rare benign mesenchymal tumor and only sporadic cases have been previously reported. The present study reports the case of a 58-year-old man who presented with an incidentally detected solitary pulmonary nodule. Based on comparisons with serial previous chest and spine radiographs, a growth pattern change in the nodule (initial gradual growth over 4.5 years, then recent no growth over 2.5 years) was identified. The nodule was diagnosed as a benign clear cell tumor of the lung (CCTL) following surgical resection. Few studies have previously reported interval growth of CCTLs and the growth pattern of CCTL is not yet well known. To the best of our knowledge, this is the first reported case in which the growth pattern change of CCTL was identified via serial imaging over 7 years of follow-up.
肺透明细胞瘤是一种罕见的良性间叶组织肿瘤，此前仅有散发病例的报道。本研究报告了一例58岁男性患者，其偶然发现一个孤立性肺结节。通过与之前系列胸部和脊柱X线片对比，发现该结节的生长模式发生了变化（最初4.5年逐渐生长，随后2.5年无生长）。手术切除后，该结节被诊断为肺良性透明细胞瘤（CCTL）。此前很少有研究报道CCTL的间隔期生长情况，其生长模式也尚不明确。据我们所知，这是首例通过7年随访的系列影像学检查确定CCTL生长模式变化的报道病例。
