Subpubic cartilaginous cystic lesion presenting as a vulvar mass: a case report.
BACKGROUND
A subpubic cartilaginous cyst is a rare and innocent defect originating from the symphysis pubis and may present as a vulvar mass and/or chronic abdominal pain. The symphysis pubis is a non-synovial amphiarthrodial joint that forms a fibrocartilaginous union between the two pubic bones and in general lies without mainstream interest, despite its clinical relevance. This case report focuses attention on this joint.


METHODS
A 55-year-old Caucasian woman presented with a painful and rapidly increasing vulvar mass. Imaging techniques revealed a cyst-like structure originating from a degenerated symphysis pubis. The cyst was excised, however, recovery was complicated by a symphysiolysis.


CONCLUSIONS
A subpubic cartilaginous cyst is a rare cystic lesion originating from the symphysis of the pubic bone which presents as a vulvar mass which might be complicated by symphysiolysis. Several diseases affect the symphysis pubis and result in significant discomfort and disability in patients. The symphysis pubis is therefore clinically important and should not be omitted in the differential diagnosis of a vulvar mass and/or chronic abdominal pain.
