高年男性に発症した嚢胞成分を認めないsolid-pseudopapillary tumor (SPT) の1例

: We encountered a solid pseudopapillary tumor (SPT) without any cyst component in an elderly man. A literature survey of SPT without cystic component suggested that the size and vascularity of a tumor were related to lack of cystic component. The prognosis of this disease was comparatively good, but elderly or middle aged case and cases without capsule seem to have high malignant potential.
