Haemangioma of the zygoma presenting as a tumour in the maxillary sinus

Computer guided resection and reconstruction of intra-osseous zygomatic hemangioma: Case report and systematic review of literature

OBJECTIVES

to systemically integrate the available data on various published treatment strategies for intraosseous hemangioma of the zygoma in an updated comprehensive systematic review, and to present a new case of treated resection and immediate reconstruction using computer guided patient specific composite graft.

CASE PRESENTATION

A 29 years old female patient with intraosseos zygomatic hemangioma treated using computer guided resection and immediate reconstruction. The resection was performed using a resection template constructed based on preoperative 3D planning. The reconstruction was performed using ramus bone graft and titanium mesh. The patient was followed up for 3 years with no complications.

METHODS

An electronic search was performed on 3 data bases; additional hand search of bibliographies of selected articles was performed. Eligibility criteria include human studies presenting intraosseous zygomatico-orbital hemangioma with clearly reported therapeutic strategies.

RESULTS

53 articles with 73 cases were included. The lesion was highly prevalent in females compared to males (2.28:1). Fifth decade represents the highest prevalence with mean age of 44.1 ± 1.8 years. The main patient concern was swelling and facial deformity. Total tumor resection can assure no recurrence, while partial resection and curettage are associated with high recurrence rate.

Radiotherapy in the Maxillary Hemangioma

We present the case of a large maxillary hemangioma treated by radiotherapy. Only 4 cases managed by radiotherapy have been reported in the literature, and most authors negate the radiosensitivity of the tumor. In our patient, the outcome was excellent; by 6 months tumor reduction was more than 50%. This is the first case referred to in the literature whose radiotherapy response was evaluated by magnetic resonance imaging. We describe the clinical and imaging findings of this very rare tumor and its evolution. We also comment on the literature reviewed.

Zygomatic Intraosseous Hemangioma: Case Report and Literature Review

Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area. They have a tendency to bleed briskly upon removal or biopsy, making preoperative detection of the vascular nature of the lesion of significant importance. There are four variants: (1) capillary type, (2) cavernous type, (3) mixed variant, and (4) scirrhous type. Generally most common in the vertebral skeleton, they can also present in the calvarium and facial bones. In the head, the most common site is the parietal bone, followed by the mandible, and then malar and zygomatic regions. Intraosseous hemangiomas of the zygoma are rare entities with the first case reported in 1950 by Schoenfield. In this article, we review 49 case reports of intraosseous hemangioma of the zygoma, and also present a new case treated with excision followed by polyether-ether ketone implant placement for primary reconstruction.

Case report: Periorbital intraosseous hemangiomas

Hemangiomas are hamartomatous proliferation of vessels. Intraosseous hemangiomas of the facial bones are rare and most commonly involve the zygoma, maxilla, mandible, and the nasal bones. A “sunburst” pattern is a typical appearance on CT scan and MRI and therefore a biopsy is not always necessary. Surgery is usually performed in symptomatic cases. The authors describe five typical periorbital intraosseous hemangiomas with a brief review of literature.

Vascular Hamartoma of the Paranasal Sinuses: Report of 3 Rare Cases and a Short Review of the Literature

The paranasal sinuses are an extremely unusual location for a vascular hamartoma. As far as we know, only 1 such case has been previously reported in the English-language literature. We report 3 new cases of vascular hamartoma of the paranasal sinuses, which occurred in a 20-year-old woman and in 2 men aged 36 and 45 years. Radiologically, the lesion in the woman was confined to the sinuses, while evidence of intraorbital extension was seen in the 2 men. No intracranial extension was seen in any patient. The diagnosis was confirmed by histopathologic examination of the excised lesions. All 3 patients were alive without recurrence at 12 to 24 months of follow-up.

Ewing's sarcoma of the facial zygomatic area bones in a young child: a case presentation

We present the case of a young patient with Ewing's sarcoma of the facial zygomatic area bones. This type of tumor in a very young child is a rare event and poses significant diagnostic and therapeutic challenges for the attending physician. In this case, the diagnosis was made by a computed tomography scan with subsequent histological confirmation. The differential diagnoses and therapeutic options are discussed.

Haemangioma of the Zygoma. Report of two cases with a review of the literature

Zygomatic haemangioma is a rare benign neoplasm occurring most frequently in adult females. The authors, after reviewing the available literature, report two cases which presented with a swelling of the zygoma. Resection of the neoplasm, immediate reconstruction with cranial bone grafts and internal rigid fixation was the treatment of choice. Results two years after surgery are presented.
