title: Recurrent bilateral corneal erosions due to an association of epidermolysis bullosa simplex Köbner and X-linked ichthyosis with steroid sulfatase deficiency.
abstract: Since early infancy a male patient now 24 years of age had suffered from painful, recurrent, bilateral corneal erosions and blister formation after minimal skin trauma. Corneal erosions are quite unusual in non-scarring types of epidermolysis bullosa. The dermatological examination disclosed that the patient had clinical hallmarks of two rare genetic skin disorders, epidermolysis bullosa simplex (Köbner) and X-linked ichthyosis. Both disorders could be traced back in the patient's maternal family to the mother's father and his brother, who were both said to have had similar eye complaints. Using biochemical means and electron microscopy of skin biopsy specimens, both diagnoses could be proven in the patient and his mother. We discuss the importance of lid hyperkeratoses in hemizygous males as a causative factor for the recurrence of bilateral corneal erosions due to the unique combination of epidermolysis bullosa simplex (Köbner) and X-linked ichthyosis with steroid sulfatase deficiency.
