Monilethrix: The Use of Trichoscopy in Clinical Diagnosis

The document discussed Monilethrix, a rare genetic disorder characterized by brittle hair that does not grow beyond a few centimeters, primarily affecting the scalp and often presenting with alopecia and follicular keratosis. The study highlighted the use of trichoscopy in clinical diagnosis, which revealed moniliform alterations (alternating wide and narrow bands) in the hair structure. The condition is inherited in an autosomal dominant pattern and involves degeneration of the hair matrix and formation of a defective cuticle.
