A solitary gastric metastasis from pulmonary adenocarcinoma: a case report

Abstract

A 77-year-old male complained of persistent cough and sputum for 2 months. Chest radiography showed a solitary mass with solid opacity in the right upper lung (RUL) (figure 1A, arrow). A CT scan of the chest demonstrated an irregular mass measuring 3.8×2.8 cm in the RUL (figure 1B, arrow). Histologically, the tumour was interpreted as a poorly differentiated adenocarcinoma (figure 1C–E). Figure 1 (A) Chest x-ray shows a round mass in the right upper lobe measuring ∼4 cm. (B) CT scan of the chest demonstrates a solitary round mass in the right upper lobe measuring 3.8×2.8 cm with a speculated margin, pleural tagging and focal enhancement. (C) H&E staining of the lung mass tissues. This shows a papillary pattern and …
