Patient's question:
A child recently developed a black spot on their waist, which felt like a small pea-sized lump. It was a bit painful when pressed hard. What is this? What could have caused it? What should be done?Doctor's answer:
According to the situation you described, it is more likely to be a pilomatricoma cyst. The reason for its recurrence may be due to skin decomposition metabolism, resulting in metabolic disorders, which then forms a small cyst below. It is a benign tumor of the skin and poses no harm to the body. Treatment is not necessary. If the contents inside are expelled, it can heal on its own. Currently, there is no need to address it, as it will gradually resolve and stabilize, possibly leaving behind a small nodule. It's best to leave it alone.
