We present herein the case of a 68-year-old man in whom metachronous liver metastasis from an alpha-fetoprotein (AFP)-producing gastric cancer was successfully treated. The patient initially underwent a distal gastrectomy for an AFP-producing gastric cancer on January 30, 1997, following which the serum AFP level which had been 228 ng/ml prior to surgery decreased to 30 ng/ml. However, 7 months after surgery, follow-up examination revealed an abnormal elevation of the serum AFP level up to 301 ng/ml, and a liver tumor was subsequently detected at segment 8 (S8) by abdominal ultra-sonography. There was no evidence of hepatitis B or C virus infections. After various investigations, he was diagnosed to have liver metastases in S6 and S8, from the AFP-producing gastric cancer, and a partial hepatectomy of S6 and S8 was performed. His postoperative course was uneventful and he was discharged on postoperative day 26. Thereafter, his serum AFP levels decreased and have remained within normal limits for 12 months since his operation. To the best of our knowledge, this is the first case of successful resection of metachronous liver metastasis from an AFP-producing gastric cancer.

Although exfoliative dermatitis (erythroderma) secondary to malignancy is commonly associated with lymphomas or leukemias, coincident gastrointestinal (GI) malignancy and erythroderma is rare. The authors recently encountered a patient with gallbladder carcinoma presenting as erythroderma. A 77-yr-old Japanese man presented with a 3-mo history of erythematous eruptions with pruritus over almost the entire body. After confirming the diagnosis of erythroderma, asymptomatic gallbladder carcinoma was found. Further investigations detected no malignancies in other organs. An extended cholecystectomy was performed. Histologic examination of resected specimens revealed poorly differentiated adenocarcinoma with negative resection margins. The eruptions with pruritus resolved within 1 wk after the operation. This is the first report, to our knowledge, of coincident biliary malignancy and erythroderma. The experience of the current patient suggests that erythroderma secondary to GI malignancy may resolve spontaneously after curative resection of the tumor.

Sigmoid mesocolon hernia is an uncommon type of internal hernia with only a few cases reported to date. This disease entity can progress rapidly to cause vascular disturbance, necrosis, and perforation of the bowel wall; therefore, early diagnosis and surgical treatment are essential. We describe the case of an intra-mesosigmoid hernia in a 60-year-old man without history of previous abdominal surgery who presented with sudden acute abdominal pain and vomiting. Based on computed tomography, which showed ascites and small bowel obstruction, we diagnosed him as having strangulation of the small intestine caused by a sigmoid mesocolic hernia and performed emergency surgery. Laparotomy revealed small intestinal strangulation, extensive engorgement, and discoloration of bowel loops. Approximately 100 cm of the small intestine extending from the ligament of Treitz had undergone strangulation and herniated into the defect of sigmoid mesocolon, leading to a diagnosis of an intra-mesosigmoid hernia. Because the incarcerated portion of the small intestine was viable, we did not perform intestinal resection and reconstruction but closed the defect in the sigmoid mesocolon. His postoperative course was uneventful.
