A suspicious vulvar mass diagnosed as a subpubic cartilaginous cyst.
BACKGROUND
Subpubic cartilaginous cysts were initially described in 1996 with few reports to date.


METHODS
We describe a 62-year-old woman with a history of breast cancer who presented with a painful, fixed, vulvar mass. MRI revealed an 18 x 10 x 12 mm3 mass extending from the anterior portion of the symphysis pubis without bony involvement. Excision was performed. Histologically, the mass consisted of fibrocartilage with extensive degenerative changes, compatible with a subpubic cartilaginous cyst. Over 24 months later, there has been no recurrence.


CONCLUSIONS
Subpubic cartilaginous cyst is a rare, benign lesion occurring on the vulva and should be considered in the differential diagnosis of a painful, superior vulvar mass.
