Abstract:
Exogenous ochronosis is a condition characterized by hyperpigmentation of the face secondary to the use of hydroquinone-containing bleaching creams. Histopathologically, it presents a collection of yellowish-brown (ochronotic) globules in the papillary dermis. Two cases of exogenous ochronosis are reported, followed by a review of the literature.
