[On micropenis, diagnosis and differential diagnoses].

The term inconspicuous penis in children covers both micropenis with a penile length less than 2.5 SD for age and other conditions with a normal length of corpora, but when the penis looks smaller due to other diagnoses. Micropenis in a newborn is a serious condition that needs immediate attention by a paediatric endocrinologist. The boy should have a continuous support until adulthood. Other conditions that resembles micropenis are for example buried or webbed penis that only affects the skin or the adherence of the skin to the penile body, so that penis looks smaller even though the corpora are of normal length. Such conditions are treated and often operated by pediatric urologists. A proper clinical examination distinguishes between these diagnoses and gives a possibility to direct the child to the proper treatment without unnecessary concern for the parents.
