Is it always blepharitis? Urbach-Wiethe syndrome (lipoid proteinosis)

A 12-year-old girl presented with recurrent crusty debris and dandruff at the base of both eyelashes despite having completed different medical treatments. She had had a hoarse voice since her early childhood. Upon anterior segment examination of the eyes, we found yellow-white, bead-like papules on the margins of the eyelids. An otolaryngologist detected multiple nodules on the vocal cords and buccal mucosa. Ultrasonography revealed salivary stones in the main parotid ducts. And a dermatological examination revealed thickened skin lesions on the elbows and knees with a biopsy showing histopathological findings of lipoid proteinosis. We diagnosed the patients as having Urbach-Wiethe syndrome or lipoid proteinosis, a rare autosomal recessive multisystem disorder with variable manifestations vary that difficult the diagnosis. The ocular manifestations are not well known among ophthalmologists, but the typical lid lesions are pathognomonic and ophthalmologists should be aware of this presentation to identify patients with Urbach-Wiethe syndrome.
