Oesophageal epidermal naevi as a feature of systematised epidermal naevus syndrome.

Systematised epidermal naevi are hamartomas developing from neural ectoderm that can be quite extensive, typically with involvement of the face, neck, scalp, arms, legs and trunk. Involvement of the gastrointestinal tract is rare. We report on a 38-year-old Caucasian woman with systematised epidermal naevus syndrome who presented with previously undescribed involvement of the oesophagus, as well as the right side of her scalp, forehead, cheeks, chin, oral mucosa, neck, arms and trunk.
