The average clinical course was (8.6±0.1) months.Clinical symptoms usually included distensible pains and secret anguish in abdomen (60.0%).No jaundice appeared in any case.Results The surgical resection was favorable for the treatment of SPT,which had excellent prognosis.No tumor recurrence were found in those following-up patients. Grossly,the cut surface showed areas of solid and papillary tissue,cystic degeneration,hemorrhage,and necrosis.Pathological features included a combination of solid and cystic components with pseudopapillae formation and degenerative regions without glands.Conclusions SPT has its uniquely clinical and pathological characteristics.Its main diagnosed points are helpful for clinical doctors to make timely diagnosis and reduce the rate of misdiagnosis and mistreatment.
