RESUMEN
A young 17-year-old man was injured on the external orbital canthus and developed a tumefaction which remained stable. After 2 years the tumefaction with exophthalmia and visual troubles. Radiological investigations suggested two diagnosis: Organized hematoma or a lacrimal gland tumor. Surgical exploration found an apparently benign tumor but histologically it was a cystic adenoid carcinoma.

Cases of cranio-facial bone anomalies were observed in 40 cases of neurofibromatosis. The cranio-facial skeletal manifestations are numerous and varied. Radiographic investigation is important to confirm the diagnosis, when neurologic and cutaneous signs are absent. The diagnosis should be easily confirmed by a conventional radiographic study.

Excepting cases of trauma, dental mobility is often mistakenly neglected as a clinical sign. Dental mobility can in fact be the first sign of osteolytic processes or tumour development. A retrospective study noted that dental mobility may be the inaugural sign of osteolytic processes in the maxillary bone in up to as many as 40% of the cases. Pyorrhea+ is often misdiagnosed leading to unnecessary avulsion and delaying diagnosis of the osteolytic disease.

Multiple keratocysts of the jaws are habitual in the nevoid basal cell carcinoma syndrome (Gorlin and Goltz. Syndrome). The authors report 3 cases of multiple keratocysts in a 28 year-old woman and in two men respectively ages of 27 and 21 years. In the third case some anomalies in which calcification of the falx cerebri were noted and suggested the Gorlin's syndrome. The limits of this syndrome with multiple keratocysts of the jaws are discussed.

The authors report a case of mandibular condyle osteochondroma on a 33 years-old woman, similar to osteocartilaginous exostosis of the long bones. The lesion was revealed by a facial asymmetry and a change of the occlusion. The diagnosis was performed on the computed-tomography examination and histopathology. The removal of the lesion has conserved the condyle without recurrence after 20 months following-up. The authors remind the uncommonly location of osteochondroma in the facial skeleton and discuss the histogenesis of this lesion in its mandibular condyle site.

The authors reports two cases of primary non Hodgkin's lymphomas of the right submandibular gland in a 50 years old woman, and of a minor gland in another woman also 50 years old. The diagnosis was difficult for the second case, and was established on the immunochemistry study. The authors discuss the epidemiological, clinical, radiological, pathological features of this neoplasm and its management.

The authors report the case of a 24 years-old man who had a first tumor in the right maxilla diagnosed as Ewing's sarcoma and treated by chemotherapy and radiotherapy. A second tumor appeared in the skull vault twenty seven months later. The histological diagnosis after removal of the lesion was IgG Lambda plasmacytoma. The revision of the histological cut of the maxillary tumor retained the same diagnosis. The patient is without evidence of local recurrence and systemic diffusion of the disease two years after treatment. The authors insist on the necessity of immunochemistry to establish the diagnosis.
