| Abstract | Introduction: Wilm’s tumor (WT) is a common renal malignancy in children. Adult extrarenal WT involving the uterus is extremely rare. Herein, we reported a case of uterine WT in an old woman who was primarily diagnosed with carcinosarcoma. Case Presentation: A 63-year-old woman presented with abdominal pain and radiologic evidence of pelvic mass originating from the uterus, which was suggestive of sarcoma. Her Serum levels of Cancer Antigen 125 (CA125), Human Epididymis protein 4 (HE4), Cancer Antigen 19-9 (CA19-9), and Alpha Fetoprotein (AFP) were found to be elevated. She underwent total hysterectomy, bilateral salpingo-oophrectomy, and omentectomy. Pathologic examination of the specimens revealed a large uterine mass with serosal surface and omental invasion. The initial diagnosis was carcinosarcoma based on the mixed epithelial and mesenchymal components observed on microscopic examination. Triphasic components of papillary, primitive tubules, and glomeruloid structures, along with mesenchymal and blastemal elements were identified upon second opinion. An immunohistochemistry (IHC) study revealed positive reactions for WT1, CKAE1 /AE3, EMA, Glypican-3, and CD56 in all components of the tumor cells. P53 expression was normal. GATA3, ER, PR, and CD10 were negative. The final diagnosis was changed to WT. Conclusions: Uterine WT is an extremely rare malignancy, which could be associated with elevated serum AFP. Diagnosis and treatment of these rare tumors pose challenges for both pathologists and clinicians. | en |
