Hämangiome der Haut

What are haemangiomata of the skin?

Haemangiomata appear as red to purple papules or plaques with a normal epithelial surface. Compression leads to partial emptying and the colour becomes less prominent. There are various types:¹

Capillary naevus

Also known as a naevus simplex this is a small, flat, red or pink patch. Seen on the neck in up to 40% of infants (stork bite), between the eyebrows (angel's kiss) or on the eyelids.¹ Stork bites may not fade but are often covered by hair over time. Facial lesions tend to fade in the first year of life.

Feuermal

A Weinfleck is a lesion lined with endothelial cells and containing blood vessels. It does not regress with age. It may be associated with Sturge-Weber-Syndrom (port-wine stain of the face, angiomas of the leptomeninges and choroid, and late glaucoma) and Klippel-Trénaunay-Syndrom (local overgrowth of soft tissue and bone in an extremity or more extensive area, port-wine stain, varicose veins, cutaneous angiomata and other variable features).²

Vin rose patch

This is a pale pink lesion appearing as a birthmark due to dilatation of the sub-papillary dermal plexus.

Venous lake

These are purple or dark-blue papules caused by dilatation of venules. They present in sun-exposed areas of the body, particularly the lips, faces and ears of elderly patients. The average age at presentation is 65 years. They are probably more common in men than in women. They are of little clinical significance, except that they can be confused with melanomas and pigmented basal cell carcinomas.³

Capillary haemangioma (strawberry naevus)

This is also known as a strawberry naevus or infantile haemangioma. It tends to regress after the first year of life and normally resolves completely after the age of 4 or 5 years. Persistent lesions or those causing obstruction of vision may require treatment.^{4 5}

Cherry angioma

Also known as Campbell-de-Morgan-Flecken, they appear on the abdomen and chest and are red, slightly elevated keratoangiomata. They do not fade with pressure.⁶

Telangiectasias

These are permanent dilatations of groups of capillaries or venules. They may be inherited or associated with atopy, sun damage, connective tissue disease, raised oestrogen levels or venous hypertension.⁷

Haemangiomata diagnosis

The compression test is useful, or the lesion can be examined with a dermatoscope and the blood-filled cavities observed. Sometimes a haemangioma may be confused with a bösartiges Melanom, if both are dark in colour and of recent origin. Reflectance confocal microscopy, optical coherence tomography, ultrasonography and multispectral imaging are non-invasive imaging techniques that can be used to support clinical examination and dermatoscopy.⁸ They can be differentiated by excision biopsy. Campbell de Morgan spots (cherry angiomas) are a type of haemangiomata which remain small and increase in number with age. A strawberry mark/naevus is a proliferating haemangioma that occurs in the first year of life and then regresses thereafter.

Venous-lake angiomas are also usually asymptomatic. Women are more likely to present for cosmetic advice or removal. They are soft and compressible. They often have a smooth surface. They are found most often on lips, face, neck and ears. Actinic skin damage often occurs around venous lakes, as they have a shared aetiology.

Haemangiomata primary care treatment

• Most haemangiomata require no treatment unless the patient is concerned about their appearance.

• Port-wine stains are usually treated by camouflage but the patient may wish to be referred for laser therapy (see 'When to refer for haemangiomata', below).⁹

• Capillary haemangiomata may regress spontaneously. However, if they affect normal development, such as development of binocular vision, or cause bleeding, or obstruction of other organs, or grow rapidly, they may need to be referred for treatment (see 'When to refer for haemangiomata', below).⁴

Prognose

This is dependent on the type of haemangiomata. Capillary haemangiomata and capillary naevi usually regress spontaneously, others are more permanent.

When to refer for haemangiomata

Referral should be considered if diagnosis is in doubt or treatment is required. Patients may require laser therapy for port-wine stains. This can be painful but a technique called pneumatic skin flattening, employed during laser treatment has been shown to reduce the discomfort.¹⁰

Other treatment options include interferon and surgical excision.¹¹
