Adenomatoid tumor of the female genital tract
Objective:
To remind gynecologists of the diagnosis of adenomatoid tumor of the female genital tract, a pathology which is often mistaken for leiomyoma, and in addition to warn of the malignant appearance of adenomatoid tumor.
Materials And Methods:
During the study period from January 1988 to May 1994, the clinical features and pathologic findings of 25 cases of adenomatoid tumor of the female genital tract were reviewed at the National Taiwan University Hospital.
Results:
The age of the patients ranged from 26 to 55 years with a median of 41 years. Adenomatoid tumor was an incidental finding during the surgical treatment of myoma (16 cases), cervical intraepithelial neoplasm (two cases), invasive cervical cancer (one case), adnexal cyst (five cases), and pregnancy with myoma (one case). Twenty-three cases had tumors in the uterine corpus and two in the fallopian tubes. Twenty percent of the patients had multiple tumors. Their sizes ranged from 1.0 to 8.0 cm. The case with the largest tumor measuring 8 cm in diameter is presented in detail. Its histologic, immunohistochemical and ultrastructural characteristics strongly support the mesothelial origin of adenomatoid tumor.
Conclusion:
Some different results were obtained than those hitherto reported in the literature, such as younger age, frequency of multiple tumors, and fewer cases accompanied by leiomyomas.
