Kissing periosteal chondroma and osteochondroma.

We present an unusual case of two synchronous chondroid matrix lesions in the proximal femur of a 16-year-old male. They were incidental findings, which subsequently underwent surgical excision and confirmed the imaging findings of a "kissing" osteochondroma and a periosteal/juxtacortical chondroma. We could not find another report of these findings in the English literature.
