RESUMO
Osseous hemangioma is a rare tumour of head and neck localisation. In this work the AA. present a case of the tumour located in the upper maxilla, considering the actual concept and the possibilities of differential diagnosis in relation with both radiologic and anatomopathological characteristics.

The union between the inferior portion of the occipital bone and the first two cervical vertebrae is the site of osseous and neurological abnormalities responsible for a wide spectrum of signs and symptoms of otoneurological interest. Often symptoms are vague with an evolution marked by temporary exacerbation or remission. The diagnosis can be difficult, and in our experience is best achieved by combining neurotologic and neurologic evaluation. We discuss the diagnosis of 6 patients with lesions at the craneovertebral junction. Arnold-Chiari malformation was diagnosed most frequently.

Hyperostosis frontalis interna is the name generally applied to skull thickening more or less restricted to the squamous portion of the frontal bone and involving, in particular, its subdural or inner surface. The association of this calvarial thickening with virilism and obesity is a clinic-anatomic complex often know as the Morgagni's syndrome and is also referred to as the Stewart-Morel syndrome or metabolic craniopathy, when accompanied by mental disorders. Hyperostosis frontalis interna is being discussed here mainly in connection with the Stewart-Morel's syndrome of which it is the pivotal feature. Frontal headache is a common complaint and is severe in some cases. In addition various neuropsychiatric disturbances may be manifested.

Microvascular invasion by carcinoma cells is one of the first steps for the potential development of metástasis. The presence of squamous cell carcinoma within capillaries and/or venules in the immediate vicinity of primary lesions of the oral cavity and oropharynx may be related to regional lymph node metastasis. To evaluate this possibility in laryngeal carcinomas we have reviewed the histopathologic features of 48 cases of this type of tumor with simultaneous surgical treatment of the primary neoplasms and the neck. In our opinion the histologic finding of such invasion is not pathognomonic for establishment of regional metástasis in epidermoid carcinoma of the larynx.

Histologic specimens from 48 patients with squamous cell carcinoma of the larynx treated exclusively by surgery were studied with special attention paid to the reactivity of regional lymph nodes. The lymph nodes were classified into four microscopic patterns of immune response: lymphocytic predominance, sinus histiocytosis, germinal center predominance and unstimulated or lymphocytic depletion. As a result no correlation were then made between the patterns and survival rate at 5 year follow-up.
