FIGURE 1 Histology of the tumor: (A), primary pulmonary carcinoma (hematoxylin and eosin staining); (B), liver metastasis with extensive necrosis (hematoxylin and eosin staining); (C), gastric metastasis. The primary pulmonary carcinoma exhibited histomorphological features of a squamous carcinoma with keratinization (A). The liver metastasis showed an increased nuclear polymorphism with bizarre nuclei accompanied by extensive necrotic areas. The squamous differentiation was still visible with several keratin pearls (B). The metastasis in the stomach exhibited features of a squamous carcinoma without signs of keratinization (C). The nuclear polymorphism is similar to the one observed in the primary tumor.
