title: Mandibular and para-mandibular tumors in children. Report of 16 cases.
abstract: Sixteen cases of mandibular tumors or paramandibular soft tissue tumors with mandibular involvement are reported. These include such rare mandibular tumors or tumor-like conditions as melanotic progonoma, intraosseous haematoma secondary to von Willebrand's disease, post-irradiation osteosarcoma, monostotic eosinophilic granuloma, aneurysmal bone cyst and osseous hemangiopericytoma. Three cases of cherubism, one of fibrous dysplasia or aggressive fibromatosis and one of central giant cell reparative granuloma are also reported. The soft tissue tumors comprise round cell sarcoma, parotid adeno-carcinoma with generalised metastases, embryonal rhabdo-myo-sarcoma, neuro-fibro-sarcoma and congenital cystic hygroma. In all the cases the disease was well advanced when the patient presented for X-ray examination. The specific X-ray diagnosis of mandibular and paramandibular tumors in childhood is more difficult than that of similar tumors in other parts of the body.
