title: [Dermoid cyst in childhood, diagnosed as ptosis].
abstract: METHODS
  A four year-old boy, diagnosed of palpebral ptosis since he was 2 by his paediatrician. At the initial ophthalmological revies he had asymmetrical upper eyelids. In the follow-up a mild ocular hypotrophy appeared in his left eye and an increasing astigmatism, which made us suspect an orbital disease. The MRI confirmed a mass, compatible with a dermoid cyst.
  
  
  CONCLUSIONS
  Due to the slow growth of these tumours, it is only with clinical follow-up and the aid of imaging techniques that we may achieve the diagnosis and offer a definitive treatment with surgical extirpation.
