There are numerous ocular and neurological lesions in ECCL, which occur ipsilaterally to the skin lesions. Particularly common, however, are what are called epibulbar choristomas; histologically these choristomas, like the skin lesions, are epibulbar dermoids10 or fibrolipomas. The severity of associated neurological disorders is important for the prognosis. These disorders, which do not correlate with the extent of the skin lesions2 or with radiological anomalies,4 range from no abnormalities at all to convulsions and severe psychomotor dysfunction. In conclusion, nevus psiloliparus is both a marker for and the first visible sign of ECCL. Meticulous ophthalmologic and neurological examination is crucial for any infant presenting with this particular fatty tissue nevus. Imagining studies should also be performed to rule out associated disorders.
