原發性卵巢固狀偽乳突狀腫瘤

Solid pseudopapillary neoplasm of the ovary

固狀偽乳突狀腫瘤比較常發現在胰臟，非源生於胰臟的固狀偽乳突狀腫瘤極為罕見，英文文獻的案例也少見到，是一種低度惡性且預後良好的的腫瘤，好發於年輕女性。組織學上包含固狀、囊狀及偽乳突狀的型態，在免疫染色上以對ß-catenin有反應及E-cadherin不反應為主要依據。在這邊報告一名37歲女性罹患左側卵巢腫瘤，之後接受經腹腔左側輸卵管卵巢切除術，意外發現為固狀偽乳突狀腫瘤，手術切除為第一線治療，雖為低度惡性的腫瘤，仍建議持續追蹤後續復發的可能性。

Solid pseudopapillary neoplasm, characterized by solid, cystic and pseudopapillary growth pattern tumor with positive immunohistochemical staining of ß-catenin, but negative staining of E-cadherin, represents 1-3% of all pancreatic tumors and is of low malignant potential with better clinical outcomes, but it is extremely rarely found outside the pancreas. In the English literature review, only a few cases of extra-pancreatic solid pseudopapillary neoplasm have been reported before. Herein, we reported a 37-year-old woman who was diagnosed of solid pseudopapillary neoplasm of the ovary after laparoscopic salpingo-oophorectomy. Postoperative course and follow-up period was uneventful. Due to the rarity, we discuss this unusual disease-solid pseudopapillary neoplasm of the ovary.
