(A) The skin lesion on the right frontal scalp was a 0.7-cm, firm, fixed, round, painless erythematous nodule. (B) Histopathologic findings of the skin biopsy sample showed a metastatic adenocarcinoma with features of signet-ring-cell carcinoma (H&E stain, ×200). (C) Abdominal CT revealed a multilobulated low-attenuation mass in the right hepatic lobe with multiple satellite lesions. (D) Histopathologic findings of the liver biopsy showed poorly differentiated adenocarcinoma infiltration (H&E stain, ×200). (E) Immunohistochemical staining showed that the tumor cells in the liver mass were positive for cytokeratin 19 (CK 19) (×200).
