Diagnostic Considerations

Also consider pili torti, trichorrhexis nodosa, and pseudomonilethrix.

Trichoscopy performed with a handheld dermoscope or a videodermoscope may be useful in distinguishing monilethrix from other scalp disorders. [21]

Hypotrichosis in one family was evaluated, with some members having monilethrixlike scalp hair. A novel deletion mutation in the DSG4 gene underlies autosomal recessive hypotrichosis with variable phenotype. [22] Thus, mutations in the DSG4 gene may result in both hypotrichosis and monilethrixlike scalp hair.
