Angiosarcoma of the premaxilla

Endoscopic treatment of ethmoidal hemangioendothelioma: case report and review of the literature

Hemangioendothelioma (HE) is a rare vascular tumor of endothelial cell origin that usually involves long bone or soft tissue. However, there are cases of head and neck involvement. In the literature, only 19 cases of nasal involvement are described. We report a case of an 18-month-old child who had HE of the ethmoid sinus. Endoscopic resection of the tumor was performed. The patient is well without any recurrence after 4 years of follow-up. Because of its rarity, the literature on HE in the nasal cavity and paranasal sinus is reviewed and its management is discussed.

Angiosarcoma of the superior vena cava

The first reported case of an angiosarcoma apparently arising from the superior vena cava is presented. The patient, a 20-year-old white man, was treated by surgical excision and reconstruction with dacron grafts from the left and right brachiocephalic veins to the right atrium. This was followed by a course of mediastinal irradiation. The patient remained clinically disease-free at 24 months post-treatment. The patient had occasional occupational exposure to polyvinyl chloride.

Angiosarcoma of the head and neck

Angiosarcomas are uncommon tumors of the skin and soft tissues, but occur in endothelial cells of almost any internal organ. When they occur in the skin, the head and neck are the most common sites of origin. Nothing is pathognomonic about their clinical presentation, and the pathologic diagnosis can only be established by biopsy. The frequent multicentric nature of the tumor and propensity for extensive subcutaneous spread require wide treatment fields, whatever the modality of therapy, and account for the low survival reported. Four cases and their outcome are reported, with only one patient achieving an apparent cure following irradiation therapy. Based on experience and extensive review of the literature, a best therapeutic approach cannot be recommended. Since the outlook for cure is so unfavorable, there appears to be a need for cooperative studies using surgery, irradiation, and perhaps, chemotherapy.

Angiosarcoma of the maxillary antrum: report of a case with brief review of literature

An additional (fifth) case of primary angiosarcoma of the left maxillary antrum in a 10-year-male is presented. The patient was given Co60 radiation therapy pre- and post-operatively (4,000 and 5,000 rads respectively). The patient had three recurrences up to June 1977, after which he did not report for further follow-up.

Angiosarcoma of the maxillary sinus: literature review and case report

A rare case of angiosarcoma of the maxillary sinus is reported. Review of the literature concerning angiosarcoma of the head and neck revealed 14 previously published cases involving the nose, nasal sinuses, and nasopharynx. Angiosarcoma of the skin and soft tissues of the head and neck differs in behavior from that affecting the nose, nasal sinuses, and nasopharynx. The case reported presents the protracted clinical course of this malignant tumor.

Angiosarcoma of venous origin arising in radial nerve

A case of angiosarcoma felt to arise from a vein within the radial nerve is presented. Endovascular angiosarcoma arising in a vein is unusual and only one case of angiosarcoma in a peripheral nerve has been previously reported. Microsurgery followed by radiation has led to a 36-month tumor free survival.
