Malignant fibrous histiocytoma of the maxillary sinus.

A rare localization of a malignant fibrous histiocytoma is presented. Review of the literature showed that the biological behavior of this group of tumors is obscure. The histomorphologic pattern does not always reflect the malignant character, the tendency for recurrence, and the metastasizing potential of the individual tumor. Radiotherapy is ineffective, so the surgeon must opt for radical excision. Additional clinical reports, long-term follow-up, and electron microscopic studies are needed to establish the biological behavior of this group of tumors.

Recurrent cementifying fibroma of the maxilla: report of case.

A case of recurrent cementifying fibroma of the maxilla has been presented. When the lesion was excised in 1948, it was reportedly well delineated from surrounding bone. There was no delineation of the tumor from the surrounding bone at the time of the operation in 1972.

Chondrosarcoma of the nasal septum extending into the maxillary sinus.

A case of chondrosarcoma of the nasal septum extending into the maxillary sinus is presented. These cartilaginous tumors are rare in the head and neck, with only 21 reported in the maxilla and four in the nasal septum. Careful histologic analysis is required for correct diagnosis. The present case was treated with an en bloc ethmoidectomy and medial maxillectomy, followed by fast neutron radiation therapy. The therapeutic program is analyzed for opportunity to provide an excellent chance of cure.

Cemento-ossifying fibroma of the orbit.

Cemento-ossifying fibroma presents with ophthalmic symptoms and signs rarely. We report the clinical and pathological findings in a case of cemento-ossifying fibroma of the right maxilla with extension into the orbital floor causing intermittent vertical diplopia, proptosis, and upward displacement of the globe. Compression of the nasolacrimal duct produced epiphora early in the course of the disease. Fibrous dysplasia has often been diagnosed in other cases of benign monostotic fibro-osseous conditions. Ossifying fibroma is easily confused with fibrous dysplasia. The histopathological difference between the two lesions is described.

Myxoma of the maxilla: report of case.

A review of the literature and a report of a case of myxoma of the maxilla in a 1-year-old Negro girl have been presented. This case is interesting because of its rarity at this age and its location. Originally, a Weber-Ferguson approach was considered. However, a transoral approach provided excellent access for complete visualization and removal of the tumor. This reinforces the advantages to the patient that result from the cooperation of different surgical services.

Ultrastructure of odontogenic keratocysts.

The ultrastructural features of an odontogenic keratocyst are described. The results of the investigation suggest that the basal lamina complex in the odontogenic keratocyst appears to be morphologically normal. The frequently observed splitting of the epithelium from the capsular tissue is marked by the separation of the epithelium and the basal lamina complex from the connective tissue. The morphologic features of the parakeratinized surface zone of the epithelium suggest that the odontogenic keratocyst may be characterized by "incomplete" parakertinization.
