Typical and subtle atypical presentations of endometriosis

PURPOSE OF REVIEW: To review the concept of typical, subtle and invisible endometriosis and analyze the evolution and progression of the disease, as well as some factors possibly involved in the pathogenesis. RECENT FINDINGS: Although rejected by Redwine, the concept of non-visible endometriosis has been proven to exist. Some new ideas on the implication of reactive oxygen species in the development of endometriosis and its early stages are described here. SUMMARY: The increased diagnosis of endometriosis can be explained not only by the increased experience and ability of the surgeon to detect typical and non-typical endometriotic lesions, but also by a better understanding of the pathogenesis.
