Question
6/11: On the third day after my son’s birth, a millet-sized hard nodule was found on his right abdominal wall. There were no abnormalities in the color of the skin on the surface, and the nodule could only be felt by pressing slightly with a finger. When pressed, there was a reaction on the child’s face. We went to the hospital for color Doppler ultrasound and other checks, and everything was normal.
9/27: Due to the change in weather, he had a slight cold and recovered after taking medicine. Those two days, because of the colder weather, we dressed him more warmly and didn’t give him a bath. When we bathed him on the 29th, we found that the nodule on the right abdominal wall had expanded horizontally like a belt.
Answer
A biopsy should be performed to determine the nature and cause of the nodule.
