Double dermal sinuses: a case study.
BACKGROUND
Dermal sinus tracts are rare congenital lesions located in the midline characterized by a cutaneous pit or dimple. They occur all along the midline neuroaxis, from the nasion and occipital area down to the lumbar and sacral regions, most frequently in the lumbar and lumbosacral region.


METHODS
Here we report a 5-year-old girl who presented with occasional headache. There were two dimples, one on the dorsal aspect of her head and another on her neck.


CONCLUSIONS
Dermal sinuses are almost always singular and the co-existence of double dermal sinuses has not been reported previously.
