A concealed penis mimicking penile agenesis in an infant with trisomy 13.
Penile agenesis results from failure in the development of the genital tubercle and is rarely associated with chromosomal abnormalities. We report on an echographic prenatal diagnosis of penile agenesis associated with trisomy 13. At birth, the contour of the penile shaft and the glans could not be seen. However, a careful palpation allowed us to determine that the penile shaft was concealed and normal in size, rather than penile agenesis being present. To our knowledge, a concealed penis associated with trisomy 13 has not previously been described.
