[Multiple ground-glass opacities nodules].

INTRODUCTION: Ground-glass opacities nodules are frequently detected with the advances of radiological imaging. These can be preinvasive lesions such as atypical adenomatous hyperplasia but also invasive lesions. It leads to question in patients with lung cancer about treatment strategy and follow up.

CASE REPORT: We report the case of a 72 years-old woman followed for a lung adenocarcinoma with an EGFR mutation of the right upper lobe stage IIb. The CT scan shows multiple pure ground-glass opacities in the same lobe of the primitive tumor but also in the other lobe. On the piece of lobectomy, histopathology of two ground-glass opacities showed atypical adenomatous hyperplasia.

CONCLUSION: Ground-glass opacities nodules could be found in patients with an operable lung cancer. These can be multiple and match with atypical adenomatous hyperplasia but also carcinomas lesions. The radiological surveillance is still the standard. The strategy for surgical resection has to be defined especially in case of multiple lesions which can require repeated surgical resection.
