In the study, the majority of cases with noninfectious skin lesions were diagnosed with conditions such as miliaria, transient neonatal pustular melanosis, and neonatal cephalic pustulosis. Miliaria, also known as heat rash, occurs due to blocked sweat ducts, leading to pustules. Transient neonatal pustular melanosis is a benign condition characterized by vesicles and pustules that resolve without treatment. Neonatal cephalic pustulosis is another common noninfectious cause, presenting as pustules on the face and scalp. These conditions are typically self-limiting and do not require extensive infectious workups.
