Uterine adenomatoid tumors confirmed by immunohistochemical staining

Abstract 

We present a 39-year-old nulliparous woman who consulted our clinic for an 8-year history of infertility with no notable symptoms. There apparent uterine leiomyomas were found incidentally on clinical examination and imaging. The surgically enucleated specimens were white in color with variable consistency poorly defined margins. The tissues stained positive for cytokeratin but were negative for CD34 antibodies, indicating a mesothelial origin. Staining for vimentin and HBME1 was also strongly positive, supporting a mesothelial origin of the tumors. The patient became pregnant 6 months after surgery. A healthy male infant was delivered at term. Immunohistochemical staining establish the diagnosis of benign adenomatoid tumors derived from mesothelial tissue.
