How does a dermatoscope work?

Dermatoscopes use light and magnification to help a dermatologist see how a person’s skin looks in more detail. Dermatoscopes help show details in the outer layer of skin that would not be visible to the naked eye.

Can a dermoscopy detect melanoma?

When used by specialists, dermoscopy is better at diagnosing melanoma compared to inspection of a suspicious skin lesion using the naked eye alone. Dermoscopy is more accurate when interpreted with the patient present rather than using dermoscopy images.

When do you use a dermatoscope?

The main purpose for using dermoscopy is to help correctly identify lesions that have a high likelihood of being malignant (i.e., melanoma or basal cell carcinoma) and to assist in differentiating them from benign lesions clinically mimicking these cancers.

What does a melanoma look like under a dermatoscope?

Melanomas have features indicating their melanocytic origin: Network. Aggregated brown or black globules. Site-specific features e.g. parallel pattern on palms and soles, follicular openings on facial skin.

How is dermoscopy performed?

Dermoscopy is performed with a handheld instrument called a dermatoscope. The procedure allows for the visualization of subsurface skin structures in the epidermis, at the dermoepidermal junction, and in the upper dermis; these structures are usually not visible to the naked eye [2-4].

What magnification is a dermatoscope?

Handheld dermatoscopes usually allow a 10-fold magnification, which is usually satisfactory for the daily practice.

What tool do dermatologists use to look at moles?

A dermatoscope is a handheld instrument, a bit like a magnifying glass. It can make things bigger (magnify) by up to 10 times. Your specialist puts some oil or gel onto your skin. They then hold the dermatoscope on to your skin so they can examine the area very closely.

How accurate is dermoscopy?

The sensitivity of dermoscopy has been reported to range from 60% to 100%, depending on, among other factors, the level of experience of the examiners and the diagnostic difficulty of the evaluated lesions. Although dermoscopy improves the diagnostic accuracy for melanoma, it cannot replace histopathologic examination.

Is Stage 1 melanoma serious?

It is the most serious type of skin cancer and can spread to other parts of your body. However, if you find melanoma early, treatment works well and can lead to a cure. One of the most important causes of melanoma is exposure to too much ultraviolet light in sunlight.

Can nodular melanoma be treated?

Treatment for Nodular Melanoma

Nodular melanoma is highly curable when diagnosed early. However, because nodular melanoma grows so quickly, it is often found at a more advanced stage. The goals for treatment of nodular melanoma are to: cure the cancer.

Can you survive nodular melanoma?

Outlook and survival

Nodular melanoma is the most dangerous form of skin cancer. It grows and spreads more quickly than other types, and a doctor usually diagnoses it at a later stage. If melanoma has not spread, the 5-year survival rate is 98.4 percent.

How long can you live with nodular melanoma?

According to research, the 5-year survival rate for nodular melanoma is 51.67 percent . However, statistics show that if any type of melanoma is found, diagnosed, and treated before it begins to spread, the 5-year survival rate is much higher, between 95 and 100 percent.
