30% of skin tumors are misdiagnosed as pigmented nevi

Many people actively seek treatment for pigmented nevi because they are worried about their malignant transformation. In fact, the malignant skin tumor that is most closely related to pigmented nevi is melanoma, which is also the most malignant tumor in dermatology. Let our experts briefly introduce to you how to judge the misdiagnosis of skin tumors, hoping to help you!

How to judge misdiagnosis of skin tumor? Expert introduction:

Chinese people are more prone to acral malignant melanoma, so if you find pigmented moles on your hands or feet, it is best to go to a dermatologist for a check-up, and it is also best to be proactive in treatment.

There are some external manifestations when a mole turns into melanoma, such as pain and itching, ulceration, and changes in a short period of time. We should also be vigilant about some moles that are easily irritated by friction, have a large area, uneven color, and unclear boundaries. The diagnosis of melanoma requires skin pathology examination.

Pigmented nevus are easily confused with some common skin malignancies, such as basal cell carcinoma and squamous cell carcinoma. Many people are misdiagnosed as pigmented nevus in the early stages of these tumors. Although these skin malignancies have a relatively good prognosis, they often occur in exposed areas such as the head and face, and the ulceration and erosion in the later stage can cause serious disfigurement.

Therefore, if you find tumors or strange spots on your skin, you must go to a dermatologist for treatment.

It is now generally recognized that Mohs micrographic surgery is the best method for treating common skin malignancies. It can increase the five-year cure rate of primary skin basal cell carcinoma from 93% to more than 99%, while ensuring that the surgical incision is minimal. Therefore, patients with skin tumors are best to go to the dermatology department to choose this method for treatment. The Department of Dermatology of Peking University First Hospital has counted more than 100 cases of Mohs micrographic surgery and found that 30% of skin tumor patients were misdiagnosed as pigmented nevi. Therefore, it is very important to strengthen the pathological diagnosis of suspicious pigmented nevus-like skin lesions.
