RESUMEN
Symptomatic renal metastasis from a primary lung malignancy elsewhere in the body is an uncommon feature in disseminated cancer. We report a case of a 1-cm primary squamous cell carcinoma (SCC) of the lung with renal metastasis initially misdiagnosed as primary renal cell carcinoma in a 65-year-old man who presented with left lower quadrant pain.

Hepatocellular carcinoma is a fatal disease with median survival less than 6 months. About 50% of hepatocellular carcinoma patients showed distant metastasis at earlier stage. Common metastatic sites are lung, intraabdominal lymph nodes, adrenal gland or bone, in order of frequency. Renal metastasis from hepatocellular carcinoma is rare with the incidence of 1.2-4.3% at autopsy. Lack of clinical symptoms and signs make it difficult to diagnose metastatic renal cancer before dying of. Common primary sites of metastatic renal cancer are malignant lymphoma, lung, stomach or breast. We report a case of hepatocellular carcinoma with renal metastasis. A 54 female patient was found to have coincidental right hepatic and right renal tumors on abdominal ultrasonographic and computed tomographic examinations. After the percutaneous needle biopsy on the right hepatic tumor and right renal tumor, histopathologic and immunohistochemical studies ultimately confirmed the diagnosis of hepatocellular cracinoma with renal metastasis. Intraarterial chemotherapy with cisplatin for primary hepatocellular carcinoma and intraarterial embolization for renal metastatic lesion were performed.

Adenoid cystic carcinoma (ACC) is a malignant epithelial neoplasm of typical histologic features and biologic behavior. It most often arises in the major and minor salivary glands of the head and neck, but has been noted in the trachea, lung, breast and elsewhere. Its biologic behavior is characterized by slow but aggressive growth with multiple local recurrences and frequent distant metastases, often over a period of years. Lung is the most common site of metastasis followed by bone, brain and liver. Herein, we report a solitary renal metastasis of ACC which occurred 8 years after successful extirpation of the primary tumor in minor salivary gland.
