RESA SERRANO, Elena  e  GONZALEZ JIMENO, Alicia. Black lingual injury in an infant, what is it?. Rev Pediatr Aten Primaria [online]. 2020, vol.22, n.85, pp.e31-e34.  Epub 03-Ago-2020. ISSN 1139-7632.

The black hairy tongue is a benign and self-limited pathology, rare in Pediatrics, caused by the colonization of chromogenic bacteria and yeasts and the concomitant presence of exogenous factors. Clinically it is characterized by brownish-black coloration of the lingual dorsum, associated with hypertrophy, hyperkeratosis and elongation of filiform papillae giving the tongue a villous appearance. Its diagnosis is fundamentally clinical, without other complementary studies being necessary. We present a case of a two-month-old baby with black hairy tongue with a good response to topical urea.
