Spontaneous rupture of hepatocellular carcinoma (HCC) is sometimes encountered clinically. We experienced a case of spontaneous rupture of a HCC, which was surgically resected along with the diaphragm.A 74-year old woman presented with anemia. Preoperative imaging suggested a tumor arising on the diaphragm. After thoracotomy and laparotomy, the intraoperative diagnosis was changed to spontaneous rupture of a HCC with invasion to the diaphragm and right lower lung. Wide resection of the diaphragm including an area measuring 13×10 cm, partial resection of the right lower lung and right hepatectomy were performed. The defect in the diaphragm was reconstructed by suturing with a reversed latissimus dorsi muscle flap.There was no recurrence of HCC 7 years after surgery. Furthermore, the patient had no muscle weakness in the right arm during daily living activities.In conclusion, a good outcome may be obtained by combined resection of a ruptured HCC along with the diaphragm, even if the tumor has infiltrated the diaphragm. A latissimus dorsi muscle flap is considered to have a better antibacterial effect than an artificial mesh prosthesis, and is suitable for patients requiring wide resection of the diaphragm

Palaeoenvironment and resource use in the prehistoric Amami and Okinawa islands were investigated based on archaeofossils of vertebrate fauna. Evidence of forest animals such as wild boars and tortoises shows that the islands were covered with evergreen broadleaf forests in the Shell Midden period (ca. 5000 BC-AD 1100) but clearance started in the Gusuku period (12th-15th centuries) and spread rapidly thereafter. Most of the fish found in the archaeofauna live in and around coral reefs and are the same as present, demonstrating that the maritime environment of the islands has been constant from the Shell Midden period to the present. Fishing of coral reef fish and wild boar hunting had been consistently predominant through the Shell Midden period except at Noguni shell midden, the oldest Holocene site of the Ryukyu Islands, where fishing is almost absent. The introduction of pigs and cattle into the Ryukyus possibly dates back to the Shell Midden period but, if anything, they seem to have been minor subsistence elements at that time. In the Gusuku period, the breeding of domesticated animals flourished, while fishing and hunting declined. These changes in land environment and vertebrate resource use in the Gusuku period are presumed to have been provoked by the development of agriculture including rice cultivation
