Abstract:
Spinal dysraphism, first described by Lichtenstein in 1940, is a congenital anom- aly due to incomplete fusion or malformation of the midline dorsal embryonic structures including the ectoderm, mesoderm, and neuroectoderm. Spina bifida occulta is a spinal dystraphism and a manifestation of a midline defect of osseous spine and related structures without cyst formation. Spinal dysraphism may be associated with hypertrichosis, lipoma, dimpling, pigmentation, hemangioma, congenital scar, sinus, cyst, or skin defect in the midline dorsal area. We observed a 23-year-old female patient with spina bifida occulta who had a blue scar surrounded by circumscribed hair growth of the lumbosacral area since 1-montb-old age. Histopathologic finding of the blue scar revealed common blue nevus showing intradermal melanocytes and melanophages. Spine X-ray showed hemivertebra of L5 and spina bifida occulta of Sl. There were no abnormal neurologic signs.
