“…17,20,21 It was reported that large cell and small cell carcinoma lead to gastrointestinal metastases more often than other histological types. 21,22 This is the first documented case of lung sarcomatoid carcinoma invading the small intestine and accompanied by leukocytosis. The morphology of sarcomatoid carcinoma cells from both lung and jejunal lesions was similar and the immunohistochemical stains for CK, EMA, and vimentin were positive while that for CD20 was negative.…”

Sarcomatoid carcinoma is an extremely rare biphasic tumor characterized by a combination of malignant epithelial and mesenchymal cells. Limited data on sarcomatoid carcinoma showed that most cases occurred with advanced local disease and metastasis, and paraneoplastic syndromes were rare. We present the case of a 63-year-old man with lung sarcomatoid carcinoma associated with jejunum metastasis and leukocytosis, and its clinical, macroscopic, and histopathological features. This case emphasizes the importance of recognizing paraneoplastic syndromes and metastasis of sarcomatoid carcinoma at diagnosis.

“…Intussusception due to intestinal metastasis is extremely uncommon in patients with pri mary lung cancer. 8) Including the case described here, only 4 cases of intussusceptions arising from gastrointestinal metastasis from pleomorphic lung carcinoma have been reported in the English literature (Table 1). 3,9,10) A combined analy sis of these cases showed that the mean age of the patient was 63.3 years; gender was exclusively male; and the jejunum was the most common metastatic site.…”

Intussusception is the second most common abdominal emergency in children. On the contrary, it is rare in adults. Most of adult intussusceptions are caused by definable structural lesions, and about half of these lesions are malignant. However, intussusception caused by gastrointestinal metastasis from lung pleomorphic carcinoma is extremely rare, and only a few case reports have been published thus far. We present a rare case of gastrointestinal metastasis from lung pleomorphic carcinoma causing jejuno-jejunal and colon-colonic intussusceptions, and review the previously 3 published cases. Intussusceptions caused by gastrointestinal metastases should always be considered in the differential diagnosis of patients with lung pleomorphic carcinoma presenting with gastrointestinal symptoms. Metastasis-related intussusception is a poor prognostic indicator in patients with pleomorphic carcinoma, regardless of the treatment.

“…Abdominal pain, hemorrhage, and anemia were the most frequent chief complaints presenting as clinical symptoms of colonic metastases in these patients (Table 1); these metastases were diagnosed by barium enema or endoscopic examination. Early detection of colonic metastases is thought to be difficult for the following reasons: (1) physicians have limited awareness of this clinically rare type of metastasis, (2) non-specific symptoms may be considered a side effect of chemotherapy, (3) patients do not undergo colonoscopic examination unless specific abdominal symptoms arise, and (4) conventional CT scanning may have low sensitivity for the early detection of colonic tumors [9]. Recently, FDG-PET scanning has begun to be used in screening for unsuspected distant metastases from lung cancer.…”

We report a rare case of colonic metastasis from primary carcinoma of the lung. A 59-year-old man who underwent pulmonary surgery for lung cancer was referred to our hospital in June 2007. The patient complained of abdominal pain, and barium enema examination at another hospital had demonstrated a descending colon tumor. Postoperative histopathological and immunohistochemical findings indicated that the tumor was a colonic metastasis of lung cancer. Three months postoperatively, the cancer had metastasized to the brain, and the patient underwent radiotherapy. He survived for more than 1 year after colonic surgery. Clinically apparent metastases from lung cancer to the colon are rare, and in the 50 Japanese cases retrospectively investigated here, the prognosis was poor.
