Adult intussusceptions due to metastatic intestinal-tumor are very rare. A 71-year-old man with an intussusception due to intestinal metastasis of renal carcinoma is reported. To our knowledge, this is the third such patient in the Japanese literature. The patient was suffered from an intestinal obstruction six months after his renal carcinoma was detected. Laparotomy was performed, revealing that he had developed a jejunojejunal intussusception due to metastasis of renal carcinoma. The early diagnosis of metastatic intestinal tumor is difficult. It is important to bear in mind that patients with malignant tumor may already have metastasis.

A 71-year old woman initially presented with abdominal pain and an x-ray picture of ischemia of the terminal ileum. The ischemic changes were transient and reversed spontaneously. Six months later, she presented with the same complaint and an x-ray picture of ileocolic intussusception. At operation, a lipoma of the ileum was the leading point of the intussusception and ischemic changes of the ileum were evident.

Small bowel obstructions (SBOs) are common. Adhesions make up the majority of cases at 84.9%, followed by abdominal herniae and malignancies. A 71-year-old female presented with total constipation, abdominal distension, on a background of resected cutaneous melanoma nine years prior. A CT-scan showed small bowel intussusception and disseminated mucosal-enhancing lesions consistent with metastases. She was brought to the operating theatre where six areas of intussusception were identified and manually reduced. Biopsies confirmed the diagnosis of melanoma. Melanoma of the gastrointestinal tract (GIT) is rare, with most cases occurring as metastasis from cutaneous lesions. Melanomas of the GIT are usually asymptomatic in their early stages, and are often diagnosed when complications, such as obstruction or perforation occur. Management of such cases consists mainly of surgical intervention to resolve the complication. In people who present with SBO without previous surgeries or herniae, a malignant cause must be considered.

Polyploid karyotypes in diffuse large B-cell lymphoma (DLBCL) are rare and carry a poor prognosis. Extranodal polyploid lymphoma is uncommon. A 71-year-old man with back pain was found to have ileal intussusception. He underwent surgical resection and was diagnosed with DLBCL with a near-tetraploid karyotype. Despite rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone therapy, he developed recurrent disease for which he started a clinical trial. He then developed dark stools from an ileal ulcer due to progressive disease and died 2 weeks later. This is the first reported case of gastrointestinal DLBCL with polyploidy. These karyotypes require attention to extranodal disease and prompt initiation of therapy.

A 71-year-old man underwent right hemi-hepatectomyfor a hepatocellular carcinoma(HCC)measuring 18 cm in diameter. The pathological diagnosis was poorlydifferentiated HCC. Ten months after the surgery, computed tomographyrevealed a nodule 12mm in diameter in the right lung as well as 2 nodules measuring 19 and 11mm in diameter in the retroperitoneum at the cranial aspect of the left kidney. Four months later, the nodule in the right lung had enlarged to 44 mm, while the 2 nodules in the retroperitoneum had enlarged to 68mm and 34 mm. These nodules were resected and histopathologicallydiagnosed as metastasis from HCC. Twenty-one months after liver resection, computed tomographyrevealed nodules 16 and 25mm in diameter in the retroperitoneum around the urinarybladder and jejunum, respectively. One month later, intussusception resulted from the jejunal tumor. Laparoscopic surgerywas performed for both tumors, which were diagnosed as metastases from HCC. Twenty-five months after liver resection, metastasis from the HCC appeared in the left adrenal grand, at the site of the jejunal anastomosis, and in the fattytissue around the right scapula. Twenty-nine months after liver resection, the patient died of respiratoryfailure from multiple metastases in the left lung.
