Osteochondroma of the Pubic Symphysis Involved With Aberrantly Placed Minisling: A Case Report

Osteochondromas are benign bone tumors that rarely involve the pubic symphysis. This case report describes a 41-year-old woman with a pubic symphyseal osteochondroma associated with an aberrantly placed single incision sling. After an outside surgeon placed a single incision midurethral sling for stress urinary incontinence, she developed pelvic pain, dyspareunia and vaginal mesh sling exposure. Imaging demonstrated a 2.6 centimeter calcified mass posterior to the pubic symphysis. The patient underwent excision of the mass and the eroded mesh sling via vaginal and abdominal approaches. Pathology demonstrated osteochondroma aggregated around mesh. This is a rare case of a single incision sling placed aberrantly into a pubic symphyseal osteochondroma that required excision.
