Hair casts: a case of pseudonits.
Hair casts are often misdiagnosed because of their close resemblance to nits from an infestation with pediculosis capitis. In their clinical presentation both of these disorders may appear to have white keratinous material adherent to hair shafts and can look very similar. Microscopic examination provides the definitive and correct diagnosis. We report a case of hair casts, also referred to as pseudonits.
