RESUMO
The present research was conducted through the research fund of Dankook University in 2006. Rectal recurrence of gastric cancer is uncommon. A few cases have been reported, with the majority of them associated with peritoneal recurrence. A 71-year-old man visited our hospital complaining of bowel habit changes and fecal incontinence. He had undergone radical subtotal gastrectomy and postoperative adjuvant chemotherapy for advanced gastric cancer 9 years earlier. Colonoscopy showed a rigidly constricted and erythematous rectum. Abdominopelvic CT showed diffuse rectal wall thickening with enhancement. PET-CT showed a hot uptake in the corresponding area on abdominopelvic CT scan, with no evidence of distant metastasis. We performed transanal full thickness biopsy and confirmed a diagnosis of adenocarcinoma pathologically similar to the former gastric cancer. The patient was diagnosed with solitary rectal recurrence simulating linitis plastica, without gastric remnant recurrence. We report this case with a review of the literature.

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor of the gastrointestinal tract and is generally located in the stomach and small intestine. They usually present with abdominal pain, gastrointestinal bleeding, and palpable mass. Some patients present with rare symptoms that are more common in malignant GIST. Malignant GIST combined with a liver abscess has not been reported yet in the literatures. We report a case of 67-year-old woman who suffered from liver abscess combined by malignant GIST with central necrosis and fistula in the ileum. She complained of fever, chills, and abdominal pain. Abdominal CT scan showed huge liver abscess and ileal mass with air pocket. Small bowel series showed contrast material filling into the ileal GIST mass. An operation was performed and the final diagnosis was malignant GIST of the ileum with invasion into the sigmoid colon and urinary bladder.
