A 47-year-old man was diagnosed as having adenocarcinoma of the lung (T4N0M0) in August 2002. He received chemotherapy and radiotherapy. In June 2003, he complained of lower abdominal pain with palpable mass in the left lower abdomen. On abdominal CT, we recognized a mass measuring 50 mm, which we considered a mesenteric lymph node. As the mass gradually grew and pain increased, we performed lymph node resection. The lymph node was near by the Treitz' ligament, and a tumor measuring 30 mm was observed in the jejunum. Therefore, we performed jejunectomy. Pathological examination of the lesion demonstrated adenocarcinoma. The differential diagnosis between small intestine metastasis and primary small intestine cancer was difficult. As adenocarcinoma of the jejunum was negative for TTF-1 in immunohistochemical staining and adenocarcinoma of the lung was positive, we diagnosed this patient as having primary jejunal cancer. We report this rare case of double cancer involving the lung and jejunum.

A 47-year-old woman suddenly developed abdominal pain and visited the emergency room of our hospital. Chest and abdominal CT scan revealed free air in the abdominal cavity and a bulky pulmonary tumor in the right middle lobe. The perforated sigmoid colon was removed in an emergency operation. Histological examination of the resected tissue revealed undifferentiated carcinoma, but the histological differentiation could not be determined. We used immunohistochemical staining to distinguish primary non-small cell lung cancer from colon cancer; the resected tumor was positive for TTF-1 and CK7, but negative for CK20. Therefore, by using immunohistochemical staining we could diagnose the tumor of the large intestine as metastasis from non-small cell lung cancer. After the operation, systemic chemotherapy with carboplatin and docetaxel was repeated, but the lung tumor did not regress and the patient died. Autopsy examination confirmed the histology of the lung tumor as pleomorphic carcinoma. Morphological characteristics and the immunohistochemical staining pattern of the pulmonary tumor were consistent with that of the colon tumor. In Japan, this is the first report in which the initial manifestation of lung cancer was perforation of the large intestine due to metastasis.

An 88-year-old woman, with a history of resection of stage IIA lung cancer in 1998, was referred to our hospital in August 2010 complaining of upper abdominal pain, vomiting, and dark brown stools. After endoscopic examination, she was admitted with a diagnosis of Mallory-Weiss syndrome. Vomiting occurred when food intake was resumed after fasting. Intestinal obstruction was suspected on abdominal radiography, and complete small bowel obstruction was confirmed by contrast-enhanced imaging after placement of an ileus tube. A small intestinal tumor with intussusception was detected by computed tomography. At laparotomy, there was no ascites. Intussusception was found due to an ileal tumor located approximately 50 cm from the ileocecal valve, and we performed partial small bowel resection. The resected small intestine contained a submucosal tumor approximately 40 mm in diameter that had penetrated the bowel wall to reach the serosa. Pathological examination revealed a submucosal tumor that showed poor continuity with the surrounding mucosa, while the histology was squamous cell carcinoma. Immunohistochemistry showed that the tumor was CK7 positive, CK20 negative, TTF-1 negative, and CK10 positive. Based on these findings, we made a diagnosis of small intestinal metastasis at 12 years after radical resection of squamous cell carcinoma of the lung.

We present a case of a 69-year-old Hispanic male with a past medical history of type II diabetes mellitus who presented with a two-month history of abdominal pain. A CT scan was performed which identified a liver mass. Biopsy of the liver mass revealed infiltration of normal liver parenchyma by atypical glands surrounded by pale eosinophilic material. The atypical glands were positive for CK7, while negative for CK20, CDX-2, and TTF-1, consistent with intrahepatic cholangiocarcinoma. A Congo red stain was performed, which highlighted salmon-orange areas, some with a globular appearance, around the glands and within the sinusoids and vasculature. Under polarized light, these areas displayed apple-green birefringence. These findings were consistent with amyloidosis, which was further supported by identification of ALECT2- (leukocyte chemotactic factor-2-) type amyloid on mass spectrometry. To our knowledge, this is the first documented case of intrahepatic cholangiocarcinoma arising in association with LECT2 amyloidosis.
