My son has had a square shaped rash? I really dont know what it is its not red just raised skin tone bumps in the shape of a square. And one on his hand but cluttered. He will be seeing his physician in a couple of weeks but wanted to get another opinion.
Hi, thanks for writing to Chat Doctor and sharing your sons' health problem!  If I were his consulting Doctor for this case of the square shaped bump on hand/rash, I would consider only one and one possibility and that is a nevus or congenital mole! However, it could be related to hormones and infections also. He needs a physical examination especially by a dermatologist for confirmation. Overall, its nature is of congenital and benign and not to worry at all! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing him good health.
