We report a case of hairy tongue that developed in a young Caucasian
woman during systemic baricitinib therapy for severe alopecia areata.
Because she experienced good clinical regrowth of her hair during
treatment, she did not want to interrupt therapy. We recommended she
use a toothbrush to debride her tongue on a daily basis, which was
successful. Hairy tongue most commonly occurs in elderly, debilitated
males with poor oral hygiene. It is thought to occur because of overgrowth
of chromogenic bacteria and/or yeast on the tongue. This unusual side
effect during baricitinib therapy suggests that immune suppression may
play a role. Clinicians should be aware of hairy tongue development
during baracitinib therapy.
