title: Uterine adenomyoma with lymphoid infiltration simulating lymphoma.
abstract: BACKGROUND
  Uterine leiomyoma with lymphoid infiltration is a rare disease that simulates malignant lymphoma with only nine cases reported to date. We describe the first case of uterine adenomyoma with lymphoid infiltration simulating lymphoma.
  
  
  METHODS
  The specimen resected from a 30-year-old Chinese woman was a well-defined firm nodule measuring 5 x 5.5 x 5.5 cm. The cut surface was similar to that of adenomyoma, which contained dark brown spots and a cyst. Microscopically, the tumor comprised smooth muscle cells intermixed with many lymphocytes. Many lymphoid follicles were present, just locating beside one side of thin-walled blood vessels and protruding into the vessels. Endometrial-type glands and stroma were visible in the tumor.
  
  
  CONCLUSIONS
  We describe the first case of uterine adenomyoma with lymphoid infiltration simulating lymphoma.
