[Giant form of infantile myofibromatosis located on the jaw].

INTRODUCTION: Infantile myofibromatosis is a rare fibrovascular-like tumour, characterized by the development of single or multiple nodular lesions arising from cutaneous, subcutaneous, muscular bone or visceral structures, diagnosed before 2 years. OBSERVATION: We report a case of infantile myofibromatosis located on the jaw, which is unique because of its large size (12 cm), its location and its neonatal presentation. It was a voluminous proliferate tumour with an ulcerated centre, located on the left jaw. Surgical excision was complete and the diagnosis was maded on histological examination. Recovery was uncomplicated with no recurrence on follow up. DISCUSSION: Diagnosis of infantile myofibromatosis is difficult because of the clinical heterogeneity and the histopathological appearance. The histological diagnosis relies on identification of two separate components, fascicular myofibroblastic at the periphery and hemangiopericytome in the centre. The most freqaent treatment is conservative surgical excision, because recurrence rates are low and there is a possibility of spontaneous regression. Some authors recommend conservative management of very large or multiple lesions particularly if excision will result in significant functional or cosmetic morbidity.

Ectopic lingual thyroid.

Ectopic lingual thyroid is an uncommon embryological aberration characterised by the presence of thyroid tissue located in a site other than the normal, pretracheal region. The tongue is the most frequent ectopic location of the thyroid gland; the clinical incidence of lingual thyroid varies between 1:3000 and 1:10,000. We present a new case of lingual thyroid in a 10-year-old child who presented dysphagia. The radiological findings and the biopsy confirmed the diagnosis. As the mass was well tolerated, surgery was not indicated. At this time, there are no signs of complications or malignant transformation.

[Central giant cell reparative granuloma of the jaw].

The authors report a series of 22 cases of central giant cells Granuloma of the jaws. There were 12 located in the maxilla, and 10 in the mandible. The majority of lesions were observed in patients under the age of 30 years, and occurs more often in females than in males, particularly in mandibular lesions. This lesion, which the pathogenesis still remains obscure, appears as radiolucency, well or ill-defined, uni or multilocular with trabeculations coursing through the lesion. Histologic study shows giant cells, fibroblastic cells, and foci of hemorrhage and osteoid tissue. The authors insist on the problem of differential diagnosis which can make a radiolucency with giant cells. It must be differentiated especially from giant cells tumor, which treatment and course are different. Finally, the authors underline a good prognosis of this lesion, which simple curettage is generally sufficient, and which recurrences remain rare.
