What is the process of dermoscopy?

Dermoscopy is a minimally invasive skin examination technology. Through the dermatoscope, things that are invisible to the human eye can be magnified to 10 times or even 100 times. Skin structures and lesions that are generally invisible to the naked eye, such as the epidermis and the upper layer of the true epidermis, can be observed. This can effectively improve the accuracy of diagnosis. Dermoscopy is a non-invasive examination technology and can also avoid direct trauma to the skin caused by pathological sampling.

Examination scope and indications of dermatoscope:

1) Auxiliary diagnosis of skin pigmentary diseases such as: malignant melanocytic nevus, melanocytic nevus, blue nevus, solar lentigo, freckles, seborrheic keratosis, solar keratosis, chloasma, malar nevus, etc.

2) Auxiliary diagnosis of skin erythematous diseases such as psoriasis, eczema, seborrheic dermatitis, pityriasis rosea, lichen planus, etc.

3) Auxiliary diagnosis of skin tumors such as basal cell carcinoma, squamous cell carcinoma, cylindroma, cutaneous fibroma, etc.

4) Non-invasive assessment and diagnosis of nail diseases such as onychomycosis, nail lichen planus, nail trauma, subungual hemorrhage, nail melanoma, etc.

5) Non-invasive evaluation and diagnosis of hair, such as alopecia areata, androgenic alopecia, telogen effluvium, rosary method, bamboo hair, etc.

6) Auxiliary diagnosis of viral diseases such as common warts, flat warts, molluscum contagiosum, etc.

7) Selection of the scope of skin pathology resection: Due to the irregular morphology and blurred boundaries of the tumor, the scope of surgical resection can often only be appropriately expanded by resecting the area of ​​skin lesions visible to the naked eye, which is highly subjective. Dermatoscope can make the boundaries of skin malignancies more clear and assist in determining surgical margins.
