Abstract |
Hypomelanosis of Ito (incontinentia pigmenti achromians) is a cutaneous abnormality consisting of
bizarre, whorly, linear, or patchy hypopigmentation over variable portion of body surface. Multiple
assocaited defects in other systems occur in three quarters of the affected individuals. Most common-
ly, the central nervous system, eye, and musculoskeletal structures are involved. It is suggested that
the cutaneous abnormality, which is often detectable at birth or during infancy, may forewarn
pediatricians of the possible emergence of defects in other organ systems.
We have experienced a case of hypomelanosis of Ito accompanying hypomelanosis of hair color and
ureteral duplication. The involvement of hair in hypomelanosis of Ito as hypomelanotic hair is
reported for the first time.
The patient, a 2-year-5-month -old girl, was the product of non-related parents. At birth, linear or
whorl like depigmented macules of bizarre irregularity on whole body surface were found. As she
grew up, the depigmented macules on her lower extremities became less evident, but those on trunk
and upper extremities became more vivid. Concomittantly, scalp hair became hypomelanotic result-
ing a blond-like appearance. Extracutaneous manifestations were developmental delay, language
retardation, and toe-out gait. Intravenous pyelogram and voiding cystoureterogram disclosed right
ureteral duplication. The upper pole ureter formed ureterocele in urinary bladder. Ureteroceletomy
and reimplantation of ureter was performed successfully. |
