case_images: Posterior winging of the right scapula was noted, which became more prominent up on pushing against resistance (Figures 1(a) and 1(b)).

case_images: Subsequent contrast-enhanced computerized tomography (CECT) showed an ill-defined enhancing malignant lesion, obliterating the right upper bronchus, right upper lobe, pulmonary artery, and pleura (Figure 3).
case_images: Immunohistochemistry of lymph node biopsy is positive for thyroid transcription factor 1 (TTF-1) confirming metastasis from an adenocarcinoma of lung.

case_images: Histology and immunohistochemistry (Figure 4) of a cervical lymph node revealed metastatic deposits from a poorly differentiated carcinoma, most probably of pulmonary origin.
case_images: Histology of the biopsy taken from:endobronchial tumor at bronchoscopy:atypical cell clusters with oval and polygonal cells mixed with blood. Cells contain enlarged, hyperchromatic, pleomorphic nuclei and eosinophilic cytoplasm, and prominent nucleoli, compatible with adenocarcinoma of lung (H&E stain x100).
