Colonic metastasis of the bronchogenic carcinoma is quite rare. Here we document an extremely rare presentation of the lung cancer that presented with acute abdomen and was diagnosed as intestinal obstruction due to colon carcinoma initially. He underwent an urgent operation and the obliterating mass in the colon was resected and reported as "colon metastasis from epidermoid carcinoma probably of the lung". Afterwards bronchoscopy revealed an endobronchial lesion in the right lower lobe that was diagnosed as poorly differentiated squamous cell lung carcinoma. In this case, colon metastasis was diagnosed before the diagnosis of the primary disease.

The Authors present the third case of small-bowel perforation of a metastatic sarcomatoid carcinoma of the lung. A 62-year-old man underwent a right upper lobectomy because of a lung tumour infiltrating the posterior thoracic wall. The histology showed pleomorphic subtype of a sarcomatoid carcinoma (pT3 pN0 cM0). The postoperative course was uneventful and thus the patient received 5 000 cGY over five weeks. After 5 months the patient was admitted to the Surgical Department for acute abdomen. At laparotomy an advanced fibrinous, bile-stained peritonitis secondary to a solitary perforation of the jejunum 50 cm distal to the Treitz were observed. The microscopical examination showed that the perforated mass consisted of infiltration of dischoesive malignant giant cells, highly pleomorphic multi and mononucleated. The immunohistochemistry, performed with multiple keratin antibodies, revealed epithelial differentiation of malignant cells, compatible with a metastatic carcinoma, consistent to the lung primary. In conclusion, according with literature, the small-bowel perforation is a rare presentation of a metastatic lung carcinoma, and particularly of a sarcomatoid carcinoma. It should be considered in differential diagnosis of patients with acute abdominal symptoms especially in those with a previous treated lung cancer. The surgeons should be aware of the poor outcome of these patients and choose a palliative treatment.

Etiology of the acute abdomen can be difficult to determine in the acute care setting, as both medical and surgical emergencies can present with a similar clinical presentation. Prompt work-up is essential to reveal the diagnosis and allow for successful treatment. We present a rare case of spontaneous intrahepatic hemorrhage in a patient with multiple comorbidities, including multiple myeloma and lung cancer. Although the underlying cause of hemorrhage remained unknown, appropriate recognition of the patient's presenting signs and symptoms allowed for immediate treatment and satisfactory outcome.

Intussusception is a rare clinical finding in adults. Most cases occur in the distal small bowel or large intestine. We report the case of a 65-year-old woman with known non-small-cell lung cancer (NSCLC) who presented with acute abdomen and ileus-like symptoms. Abdominal computed tomography suggested ileocecal intussusception. The patient underwent right hemicolectomy and the histopathological workup showed ileal NSCLC metastasis as the lead lesion of intussusception. The classic triad of cramping abdominal pain, bloody diarrhea and a palpable tender mass, which is present in the majority of pediatric patients, is only infrequently observed in adults. Thus, symptoms are often nonspecific and the clinical presentation may be inconspicuous. Because of the large proportion of structural anomalies, adult intussusception requires definitive treatment, of which surgical resection is the treatment of choice. In patients with colocolonic or ileocolonic intussusception, malignancy should be considered and therefore en bloc resection rather than reduction is the recommended surgical technique, whereas cases of enteric intussusceptions may be reduced by limited resection of the small intestine.

An 85-year-old male with advanced squamous cell carcinoma of the lung, who was diagnosed about 10 years prior to his current presentation, suddenly complained of abdominal pain and underwent an abdominal computed tomography scan, which revealed free air and massive ascites. He was admitted to our hospital for acute peritonitis and emergency surgery was performed. During the surgical procedure, a perforation of the jejunum was diagnosed and repaired. He was diagnosed to have a metastatic tumor originating from a squamous cell carcinoma of the lung. He improved and was transferred to the former hospital on the 27th postoperative day. Jejunal metastasis from squamous cell carcinoma of the lung is rare, and the prognosis of peritonitis due to a perforated intestinal metastasis from lung cancer is poor. There have been 10 reports of jejunal metastasis of squamous cell carcinoma of the lung reported in Japan between 2000 and 2011. Therefore, when patients with advanced lung cancer present with acute abdomen, it is necessary to keep in mind the possibility of a gastrointestinal metastatic tumor.

We here describe a case of an acute peritonitis due to perforation of a small intestine tumor metastasized from a lung cancer. A 66-year-old man who had undergone a bladder cancer procedure 2 years ago and was hospitalized for the second operation, complained sudden abdominal pain. An enhanced abdominal CTrevealed a small amount of free gas and ascites in the abdominal cavity. On the same day, emergency exploratory surgery was performed with the diagnosis of perforative peritonitis. A laparotomy revealed a jejunal tumor with perforation 40 cm distal from the Treitz ligament. After surgery, the patient confessed that he had got a notice of the recurrence of lung cancer which had been treated 9 years ago. The pathological result indicated the lesion was metastasis from lung cancer. Although small intestinal metastatic tumor from lung cancer is rare, it should be considered when acute abdomen is observed.
