A New Dermoscopic Finding in Healthy Children

Arch Dermatol. 2009;145(5):596-597. doi:10.1001/archdermatol.2009.58

Dermoscopy and videodermoscopy are increasingly being used in the evaluation of hair and scalp disorders to improve our diagnostic capabilities and ease clinical management.1-5 The term trichoscopy has recently been proposed to refer to hair and scalp examination with dermoscopy.6 To our knowledge, there are no reports of dermoscopic scalp findings in healthy children.

Dermoscopic images were obtained from 19 participants, ages 5 months to 14 years, with no prior diagnosis of hair or scalp disease, during the period January 2004 to May 2008. Images were acquired using a computerized polarized-light videodermoscopy system (FotoFinderdermoscope; Teachscreen Software, Bad Birnbach, Germany), with a water interface solution (Eau Thermale Avène, Paris, France), at magnifications ranging from ×20 to ×70. Two patients were reevaluated 3 years after their initial examination. An additional patient was examined within the same day, before and after shampoo of the scalp. Bacterial and fungal cultures were obtained from 2 subjects.
