Abstract
- Adenomatoid tumor of the uterus is a rare benign tumor of the uterine serosa and myometrium. It usually appears as a small nodular lesion having a distinctive histologic appearance. We describe a case of 67-year old female with a large, grossly cystic adenomatoid tumor 7x7 cm in dimension that was located at the right uterine cornus. Microscopically the tumor had unusually extensive solid proliferation of signet ring cells with large vacuoles in their cytoplasm. Also, adenoid and honeycomb-like cystic patterns were observed. The immunohistochemical and ultrastructural studies demonstrated the mesothelial origin.
