We report a relatively rare case of solid cystic tumor of the pancreas in a 35-year-old woman with Turner's syndrome whose tumor was found by abdominal ultrasonography at our hospital in August 1999. Computed tomography and magnetic resonance imaging showed a pancreatic solid cystic tumor. Chromosomal examination due to the woman's unusually short height and primary amenorrhea showed 46, X, i(q10)/45X and she was diagnosed with Turner's syndrome. Distal pancreatectomy was conducted in July, 2000. Histological examination confirmed with the diagnosis. Both estrogen and progesterone receptors were negative in tumorous parts of the resected specimen. Pancreatic tumor in a patient with Turner's syndrome is extremely rare and its origin is unknown.
