Primary leimyosarcoma of the gallbladder is an extremely rare neoplasm. To the best of our knowledge, this is the first case in the Japanese and English literature of synchronously concomitant primary leimyosarcoma of the gallbladder and adenocarcinoma of the stomach. A 80-year-old woman admitted for right upper quadrant pain was suspected of cancer of the gallbladder and early gastric cancer based on abdominal ultrasonography, CT, MRI, ERCP and gastrointestinal endoscopy. MRI appearance of the gallbladder tumor was intermediate intensity on T1 weighed images and slightly high intensity on T2 weighed images. We conducted extended cholecystectomy and distal gastrectomy. The resected specimen histologically proved to be leiomyosarcoma of the gallbladder and adenocarcinoma of the stomach. In 21-month follow-up, the patient was well with no reccurent evidence of either malignancies.
