LONDONO, Ángela et al. Exogenous pigmentation by silver nitrate: Dermatological and toxicological aspects, case report. Biomed. [online]. 2021, vol.41, n.2, pp.234-239.  Epub 15-Jun-2021. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.5876.

Exogenous pigmentation by silver nitrate is a rare disease whose clinical manifestations appear even years after the contact, making its diagnosis difficult on occasions. It is characterized by the presence of blue-gray macules or plaques on the skin or mucosa in the contact area, sometimes very similar to melanocytic lesions and melanoma, which constitute the main differential diagnosis.

We report the case of a male patient from Medellín, Colombia, with a family history of melanoma and the presence of these lesions throughout his body.
