“A mole on the face with unclear boundaries and changing shape, said to be a halo around the mole.” diagnosis

얼굴에 후광이 있는 점이 생겼어요.

A mole on the face with unclear boundaries and changing shape, possibly with a halo around it, could be concerning for a few conditions:

1. Halo Nevus: A halo nevus is a mole surrounded by a depigmented “halo.” While often benign, any changing mole, especially with unclear borders, warrants close monitoring.
2. Atypical Mole (Dysplastic Nevus): This type of mole has irregular borders, uneven color, and can grow or change shape. They are generally benign but can sometimes progress to melanoma, so they need careful observation.
3. Melanoma: Melanomas often show asymmetry, border irregularity, color variation, and changes over time. If the mole is evolving in appearance, it could be a sign of this more serious skin cancer.

In any case, a mole with these characteristics should be evaluated by a dermatologist, who may recommend a dermatoscopy or biopsy to assess the mole further.

Here is a medical illustration of a halo nevus (후광모반). It shows a mole at the center surrounded by a depigmented (lighter) halo. This is often seen in benign conditions but should still be monitored if there are significant changes in size, shape, or color.
