Hemangioma

Hemangioma is a benign tumor, usually in the shape of a ball, but sometimes a flatter mat, formed by a collection of excess blood vessels in an area. Because blood vessel cells are usually transparent in thin smooth muscle cells, hemangiomas are usually the color of the blood that runs through them. If the blood has a lot of oxygen, or is more arterial, the color is usually bright red. If the color is dark, the blood is usually low in oxygen, venous or possibly stagnated. more...

Hemangiomas are relatively common in newborns, and tend to disappear without treatment. The appearance of the tumor may be mistaken for a sign of physical abuse.

Types

Hemangiomas are often classified by the size of the vessel affected. For example:

  • Capillary hemangioma (or "capillary nevus hemangioma", or "superficial hemangioma")
  • Cavernous hemangioma (or "deep hemangioma") -- large vessels

Hemangiomas are mostly commonly cited as a skin related abnormality. However, various types of Hemangiomas can occur within the body. Common internal occurrences of hemangiomas include the liver, among other organs (Cavernous Hemangioma).

Endoscopic view of a nasal septal hemangioma causing obstruction
From Ear, Nose & Throat Journal, 1/1/04 by Eiji Yanagisawa

A 32-year-old man was evaluated for a complete right nasal obstruction and intermittent nasal bleeding of several months' duration. Clinical examination revealed the presence of a large exophytic polypoid lesion with a friable mucosal surface that filled the right nasal airway (figure, A). Assessment of the posterior extent of this mass was difficult. Computed tomography (CT) of the nose and sinuses detected a roundish soft-tissue mass in the anterior portion of the right nasal airway; the mass appeared to originate in the anterior septum (figure, B). Findings in the paranasal sinuses were negative.

[FIGURE A-B OMITTED]

The patient underwent excision of the right intranasal lesion under general anesthesia. Careful examination with a suction revealed that the lesion had originated in the anterior portion of the nasal septum on the right side (Kiesselbach's area) (figure, C). It was removed with electrocautery, and complete hemostasis was achieved. The procedure provided for an excellent airway on the right side (figure, D). The pathologic diagnosis was a focally ulcerated capillary hemangioma. The patient's postoperative course was uneventful.

[FIGURE C-D OMITTED]

The capillary hemangioma is a common vascular tumor of the anterior nasal septum. (1) It may appear as a pedunculated friable polypoid mass on the anterior portion of the nasal septum. Its presence can cause airway obstruction and recurrent unilateral epistaxis. In this case, the lesion obstructed the nasal airway completely. CT of the sinuses helps evaluate the size and origin of the tumor and its relationship to sinus pathology, thus assisting in surgical planning. The differential diagnosis includes hamartomas, pyogenic granuloma, arteriovenous malformation, (2) and nasal polyps.

At surgery, suction helps identify the tumor's site of origin. (3) Treatment entails complete surgical or electro-cautery excision under local or general anesthesia. When available, laser excision may be an alternative.
