Extraskeletal chondroma of the masseter muscle: a case report with review of the literature.
The authors report a case of soft tissue chondroma of the masseter muscle in a 49-year-old man. The tumour was entirely composed of lobules of hyaline cartilage. The literature on head and neck soft tissue chondroma is also reviewed. To the authors' knowledge, this is the first case of muscular soft tissue chondroma in the head and neck region.
