[Oropharyngeal synovial sarcoma. Report of one case].

Synovial sarcoma is a malignant growth of the soft parts of young people, scarcely of the head and neck. The tumor classic is two-phase composed by epithelial and spindle cells. The AA. report a new case of synovial sarcoma located in the oropharynx and the treatment followed, and discuss as well the histology and the origin of these tumors.

[Mucocele of maxillary sinus].

The term mucocele designates a cyst developing from a sinus mucosa, generally the frontal and/or ethmoidal sinuses. Maxillary sinus localization is exceptional however and raises numerous diagnostic problems in daily practice. The antral mucoceles are potentially destructive lesions, often secondary to Caldwell-Luc procedure. In this article are described in some detail the clinical, radiological and histopathological features of true antral mucoceles.

[Mucoepidermoid carcinoma of the larynx. A case report and review of literature].

A new case of mucoepidermoid carcinoma of the larynx is presented. The microscopic differential diagnosis of mucoepidermoid carcinoma, the several cells stem with its malignancy degrees and its repercussion on prognostic and possible treatments of this rare growth are stressed. A review of the literature is set aside.

[Neurinoma of the thyroid gland].

Schwannomas are solitary neurogenic tumors that arise from cells of the neural sheat. They grow slowly and represent a proliferation of Schwann cells. Extracranial neurogenic tumors of the head and neck are uncommon. We describe a case of solitary cervical schwannoma placed in the thyroid area. And recall the histology, the nerves more frequently involved, diagnostic tests and the treatment of these nervous tumors.

[Hypophosphatemic osteomalacia secondary to a vascular fibrous histiocytoma].

Management of an adult woman with a 3 years untractable low back pain, allowed us to discover the existence of hypophosphatemic osteomalacia, due to a benign mesenchymal tumor (vascular fibrous histiocytoma). The prognosis of this form of osteomalacia, as in the present case, is excellent after total removal of the tumor.

[Osteosarcoma: 2d malignant tumor following treatment with radiotherapy].

The authors report a case of postirradiation osteosarcoma that appeared in a seven year old girl after having received radiation therapy for a soft tissue sarcoma. The latent period between the two malignancies was 5 and a half years and the apparently radiation-induced osteosarcoma developed within the radiation field of the primary tumor.
