Ovarian endomyometrioma with atypias: description of a case.
OBJECTIVE
To report on a patient with endomyometrioma with atypias and to review the literature.


METHODS
Case report and literature review.


METHODS
Clinical and pathologic.


METHODS
A 33-year-old nulliparous woman with right flank pain and infertility.


METHODS
Accuracy of diagnosis, hypotheses on endomyometrioma pathogenesis.


RESULTS
A 33-year-old woman with an 8-cm right ovarian mass is reported. An extensive review of the literature on this rare disease revealed only nine well-documented cases with different views on pathogenesis. The final diagnosis required an accurate sampling and the aid of immunohistochemical markers.


CONCLUSIONS
Endomyometrioma is an extremely rare entity. None of the previous cases showed cytologic atypias. The finding of atypias, in analogy with endometriosis, suggests the müllerian metaplastic theory.
