Background: Reports of metastatic sarcoma to the pancreas are limited. We reviewed the clinicopathologic characteristics of such cases.
Methods: We reviewed 124 cases of metastatic tumors to the pancreas diagnosed at Asan Medical Center between 2000 and 2017.
A 44-yr-old woman with menorrhagia and uterine fibroids underwent total laparoscopic hysterectomy, revealing several submucosal, intramural, and subserosal tan-white nodules in the uterus. Microscopic examination revealed tumors displaying 3 distinct morphologies: 1 tumor with features of conventional leiomyoma; 1 tumor with increased cellularity, staghorn/hemangiopericytoma-like vasculature, and occasional atypical cells with prominent red nucleoli and some perinucleolar halos suggesting a fumarate hydratase (FH)-deficient atypical leiomyoma; and 1 tumor with an admixture of epithelioid and spindled cells with the former arranged around blood vessels suggesting a perivascular epithelioid cell tumor (PEComa). Immunohistochemical studies confirmed these diagnoses by demonstrating loss of FH expression in the atypical leiomyoma and diffuse expression of HMB45 and cathepsin K in the tumor with epithelioid features.
