Differential Diagnosis for Penis Problem in Newborn
- Single Most Likely Diagnosis
- Phimosis: This is a common condition in newborns where the foreskin cannot be fully retracted over the glans penis. It's a normal finding in many cases and usually resolves on its own as the child grows.
- Other Likely Diagnoses
- Hypospadias: A congenital condition where the urethra opens on the underside of the penis, which can be noticed at birth. It requires surgical correction.
- Epispadias: A rare form of hypospadias where the urethra opens on the top side of the penis. It's less common than hypospadias but also requires surgical intervention.
- Circumcision complications: If the newborn has undergone circumcision, complications such as bleeding, infection, or improper healing can occur.
- Do Not Miss Diagnoses
- Testicular torsion: Although rare in newborns, testicular torsion is a surgical emergency that can lead to loss of the testicle if not promptly treated. It presents with severe pain and swelling of the scrotum.
- Necrotizing fasciitis: A severe infection that can quickly spread and is life-threatening. It's characterized by rapid progression of redness, swelling, and pain.
- Rare Diagnoses
- Diphallia: A rare congenital anomaly where there are two penises, which can be associated with other genitourinary anomalies.
- Penile agenesis: A condition where the penis is absent or underdeveloped, often associated with other congenital anomalies.
- Chordee: A condition where the penis curves downward, which can be isolated or associated with hypospadias or epispadias.
