Endometriosis infiltrating the pelvic floor muscles with histopathological correlation—A case report

Abstract

We report the case of a 29-year-old woman with deep infiltrating endometriosis who underwent robotic nerve-sparing surgery for resection of all visible lesions infiltrating pelvic and extrapelvic sites. Painful symptoms included severe dysmenorrhea, menstrual dyschezia and stranguria, with no improvement in response to hormonal treatment. The location on physical examination of a painful retrocervical nodule was identified by magnetic resonance imaging to be infiltrating the right parametrium/paracervix. During surgery, this nodule was recognized as an important retrocervical/rectovaginal lesion infiltrating the pelvic floor (i.e. levator ani and coccygeus), and was histopathologically confirmed as endometriosis infiltrating the skeletal pelvic floor muscles. A Pubmed search of the MEDLINE database in March (2019) found no publication reporting histopathologic confirmation of endometriosis infiltrating the pelvic floor muscles.
