What would be the square shaped bump on hand?
Patient: My son has had a square shaped rash? I really don't know what it is it's 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. Doctor: Hi, thanks for writing to HCM and sharing your son's 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.
