ABSTRACT
Hairs cast is a common condition misdiagnosed worldwide. Hair casts
consist of thin, bright, yellowish-white tubular concretions distributed
along the hair, also known as pseudonits due to their macroscopic
characteristics, and they should be considered as a differential
diagnosis during the evaluation of a patient with a presumed diagnosis
of nits. In this article, we report the case of an 8-year-old girl with hair
casts with partial response to treatment. The relevance of knowing
the characteristics and pathophysiology of this condition is highlighted
in order to avoid a wrong diagnosis, and consequently inadequate
treatments for the patient.
