Multiple tumors in the lungs are composed of medium‐sized, atypical epithelial cells with necrosis. Immunostaining shows that tumor cells are positive for CK7, CEA, Chromogranin A, Synaptophysin, GCDFP‐15, CK5/6 (partially), and negative for CK20, CD56, androgen receptor, alpha‐amylase, S‐100, TTF‐1, p63. These findings are compatible with metastasis of parotid gland cancer. In the background of lung abscess and bronchopneumonia with bacterial colonies. The gene discussed is NCAM1; the disease is lung abscess.
