Abstract
- <bold>Study Question: </bold>What are the characteristics of spontaneous endometriosis in cynomolgus monkeys?<bold>Summary Answer: </bold>Spontaneous endometriosis in cynomolgus monkeys exhibited similar characteristics to the human disease.<bold>What Is Known Already: </bold>One previous report described the prevalence and the basic histopathology of spontaneous endometriosis in cynomolgus monkeys.<bold>Study Design, Size, Duration: </bold>Endometriotic lesions that had been histologically confirmed in 8 female cynomolgus monkeys between 5 and 21 years old were subjected to study.<bold>Participants/materials, Setting, Methods: </bold>The monkeys died of, or were sacrificed because of, sickness consequent on endometriosis. Specimens were evaluated histopathologically with haematoxylin and eosin staining, iron staining and immunohistochemistry (CD10, CD31, α-SMA and PGP9.5), and by observing them under a microscope.<bold>Main Results and the Role Of Chance: </bold>Endometriotic and stromal cells (CD10-positive) with haemorrhage and inflammation were observed. Smooth muscle metaplasia and nerve fibres were also noted in the endometriotic lesions. Endometriotic lesions in lymph nodes were incidentally found.<bold>Limitations and Reasons For Caution: </bold>Since laparoscopic analysis for monitoring the disease state was not set as a parameter of the current study, time course changes (progression) of the disease were not assessed.<bold>Wider Implications Of the Findings: </bold>Further investigation of spontaneous endometriosis in cynomolgus monkeys may contribute to better understanding of the disease pathobiology.<bold>Study Funding/competing Interests: </bold>No external funds were used for this study.
