Vascular Dermatology and Dermatosurgery
Dermatoscopy is a screening method for examination of pigmented and other skin lesions. It is performed aiming at the preventive treatment as well as the early diagnostics of malignant skin diseases. It is used to follow up the progression of benign lesions and pre-malignant skin conditions. An optical system using artificial light allows examination of the skin lesions in depth.
Removal with Nd:YAG laser (infrared, 1064 nm)
Hemangiomas, Spider naevi
Hemangiomas are benign tumors arising from the blood vessels. Neoplasmas are benign and grow quickly or don’t change their size at all. They have a good prognosis and respond quite well to treatment.
Spider naevi are often single and they are not a symptom of another disease. They consisits of one or few central vessels and a great number of extensions which radiate outwards like a star or a spider’s web.
Hemangiomas and spider naevi are treated with Nd:YAG (infrared, 1064 nm) laser. They are frequently responsive and could be influenced completely at the first procedure. This procedure is quick and painless.
These are permanently dilated capillaries of the skin, linear, forming grid structures. They affect body areas upon intensive sun exposure or could be a manifestation of a skin disease.
They are responsive to the influence of Nd:YAG (infrared, 1064 nm) laser therapy. Several treatments are often needed. The procedures are at intervals of 3-4 weeks.
Vascular malformations (port-wine stains, cherry hemangiomas)
These are benign, red to dark purple hemispheric vascular lesions of the skin, composed of many dilated capillaries. They are rarely single. Their sizes and number tend to increase with age.
They are treated with Nd:YAG (infrared, 1064 nm) laser. A repeated treatment is often needed. The procedures are performed at intervals of 3-4 weeks.
Therapies with Er:YAG (infrared, 2940 nm) / CO2 (10 600 nm)
Laser Er:YAG (infrared, 2940 nm) and CO2 (10 600 nm) are lasers which could remove skin lesions /after a dermatologist’s inspection/, and treatment is pain-free. The advantage is that the thermal energy doesn’t cause a long-term thermal tissue injury, thus reducing the risk of unwanted complications after the procedures. The limited thermal effect leads to a minimal erythema /cutaneous flushing/ and discomfort after treatment. Depending on the lesion type and size, one to several procedures are needed, with a three week interval required. This type of laser device is successful for treatment of:
Acne and acne scars
Skin with enlarged pores, acne-prone, irregularities due to inflammatory and non-inflammatory processes affecting the sebaceous glands.
Stretch marks and scars
Stretch marks are skin defects due to over-stretching upon reduced elasticity. Scars /cicatrices/ – connective tissue extensive growth within or out of the outlines of the initial skin defect. Their formation is a normal stage of the repairing skin processes.
Pigmentations are a superficial or deeper, according to the level of the irregular accumulation of melanin in the skin, followed by a visible change in colour.
Removal with an electrocoagulator
Electrocoagulation is a method by which high temperature is reached over a small area through concentration of electric energy /diathermal current/, thus leading to coagulation or necrosis of the treated tissue. The temperature reached is high enough to cause destruction of the treated skin lesions which are instantly removed and repeated treatment is not necessary. It causes a mild bearable stinging pain.
Seborrheic verruca /warts/
Benign skin growths, raised with uneven surface, light brown to black coloured, located in the seborrheic zones. They often become inflamed in the zones of friction.
Benign lesions. Soft tissue fibromas have the same colour as the skin or are lightly pigmented. Their size vary from 1 mm to about 5 cm, some could reach a size of a pea. Most common, fibromas appear on the skin folds: axillas, groins and neck.
