ABSTRACT: Chloroquine phosphate and hydroxychloroquine sulfate are organic compounds, known as aminoquinolines for containing an amino group attached to a quinoline ring. They have been used since World War II as antimalarial agents.The article search that made up this review was carried out in the PubMed database, using the keywords “Chloroquine”, “Hydroxychloroquine”, and“Oral Manifestations”, in the period including 2005 to 2020. The sample size was 7 female patients aged 40 to 66 years, with an age predominance of between 50 and 60 years old. The predominant lesion site was the hard palate with 6 cases. To reach the diagnosis of pigmented lesions in the oral cavity, meticulous anamnesis prior to physical examination is extremely important. In this pandemic and post-pandemic period, a more detailed investigation of the medications used by the patient in recent periods, such as chloroquine and hydroxychloroquine are essential to detect if the lesion was possibly caused by these drugs.
