Atypical polypoid adenomyoma (APA) is an intrauterine tumor for which hysteroscopic tumor resection allows for fertility preservation. Complete resection is important because of the high recurrence rate of APA, but is difficult due to the lack of characteristic hysteroscopic findings. We previously reported a case in which photodynamic diagnosis (PDD) was useful for detection of APA. Here, we report two additional cases of APA treated by hysteroscopic resection with PDD. The procedure was approved by the ethical committee. Case 1: A 35-year-old female who underwent hysteroscopic surgery for a submucosal tumor suspected to be APA with hypermenorrhea. Case 2: A 37-year-old female in whom hysteroscopic surgery was performed for a residual APA lesion after hormone therapy. In Case 1, PDD identified the tumor borders and this enabled as complete resection as possible. In Case 2, lesions could not be identified clearly under white light, but some areas were PDD-positive and were excised. Among 19 specimens from these two cases and the previously reported case, all PDD-positive specimens were pathologically diagnosed as APA. The sensitivity and specificity of PDD for APA were 76.9% and 100%, respectively. These results suggest that PDD can contribute to identification of APA.
