Bilateral Trichotillomania of Eyelashes Triggered by Anxiety due to Nocturnal Enuresis: A Case Report

الملخص EN

Purpose.

Trichotillomania is a behavioral and mental disorder and is characterized by a recurring habit of pulling out one’s hair.

The differential diagnosis between trichotillomania and other hair loss conditions such as alopecia areata is difficult for ophthalmologists.

We report a rare case of bilateral trichotillomania of the eyelashes that was triggered by anxiety about nocturnal enuresis.

Case Report.

A healthy 9-year-old Japanese boy presented with a bilateral loss of his eyelashes.

His parents had believed that his loss of eyelashes was due to alopecia, an autoimmune disorder that results in hair loss, of the eyelashes.

Our initial examination revealed that he had suffered from nightly nocturnal enuresis from childhood and was scheduled to go on a school trip the following month.

He feared that his school mates might find out about his enuresis, and he said that the anxiety was the cause of the eyelash trichotillomania.

The trichotillomania was resolved by discussion among the student, his family, teacher, and school counselor.

Conclusion.

To the best of our knowledge, this is the first report of eyelash trichotillomania caused by anxiety about nocturnal enuresis.

Ophthalmologists should be aware that a patient without eyelashes may not be due to alopecia but some anxiety-producing events.

In addition, discussion of the anxiety-producing factor among the parents, teacher, and school counselors can resolve the trichotillomania.
