case_images: The serum beta-hCG was 66.2 IU/ml ( Figure 1 ).
case_images: Chest computerized tomography (CT). (A-C) Chest CT image before the first video-assisted thoracoscopic right upper wedge resection and right lower segmentectomy. (A) A mGGN of 24 mm x 14.2 mm in the apical segment of the upper lobe (red circle). (B) A mGGN of 10 mm x 8 mm in the posterior basal segment of the right lung, marked by a red circle. (C) A thin-walled cavity in the posterior segment of the left lower lobe (red arrow). (D-F) Chest CT image 2 months after the first thoracic surgery. (D, E) Postoperative changes of the right lung; no mGGN seen. (F) The mGGN in the posterior segment of the left lower lobe was enlarged at 10 mm x 17 mm and suspected as nodular consolidation (red arrow).

case_images: The chest CT showed a mixed ground-glass nodule (mGGN) (24 mm x 14.2 mm) in the apical segment of the right upper lobe which was considered to be invasive cancer and a mGGN (10 mm x 8 mm) in the posterior segment of the right lower lobe undetermined ( Figure 2 ).
case_images: Pathological appearance of ETT. (A, B) Representative HE images indicated nests and cords of intermediate epithelioid tumor cells mixed with eosinophilic hyaline-like material in normal lung tissues (x10). (C-F) Immunohistochemical staining images showed the expression of specific ETT markers, such as GATA, P63, hPL, and hCG-alpha (x10) (black arrowhead).
