Kim, Park, Baek, and Koh: Chest Wall Implantation of Lung Cancer Following CT-Guided Wire Localization: A Case Report


Tumor implantation of lung cancer at the wire localization site has not been reported previously while there have been several reported cases of chest wall implantation after percutaneous core needle biopsy and chest tube insertion for malignant pleural effusion. We report the case of a 64-year-old-man with lung cancer (squamous cell carcinoma). The patient had lung cancer implantation in the chest wall 8 months after computed tomography-guided wire localization and subsequent anterior segmentectomy of right upper lobe with mediastinal lymph node dissection.

Imaging and histology findings of a chest wall implantation from primary lung cancer following CT-guided wire localization in a 64-year-old man.

A. CT scan shows a 0.9 cm cavitary nodule in the subpleural region of the RUL. The distance between the nodule and visceral pleura is approximately 0.5 cm.
B. CT scan demonstrates that the wire tip is located at the nodule through the anterior part of the right second intercostal space.
C. Photomicrograph (hematoxylin and eosin stain, × 200) of the primary lung cancer in the RUL reveals tumor cells with intracellular bridges. This finding indicated the nodule was squamous cell carcinoma.
D. Enhanced CT scan reveals a well-defined 3-cm enhancing mass (arrows) in the right second intercostal space. The mass invades the right pectoralis minor and the second intercostal muscles.
E. Photomicrograph (hematoxylin and eosin stain, × 200) of the chest wall mass shows tumor cells with intracellular bridges. This histological characteristic was identical to that of primary lung cancer.
CT = computed tomography, RUL = right upper lobe
