Definition
An expanding number of medications have been implicated as a cause of oral pigmentation. The discoloration of the oral mucosa results from the deposition of drug metabolites or the stimulation of melanocytes by medications.
Oral pigmentations have been associated with use of phenolphthalein, minocycline, tranquilizers (chlorpromazine), antimalarial medications (chloroquine, hydroxychloroquine, quinidine, quinacrine), estrogen, and chemotherapeutic agents (doxorubicin, busulfan, cyclophosphamide, 5-fluorouracil). Some medications used in the treatment of AIDS may give increased melanin pigmentation (zidovudine, clofazimine, ketoconazole) (Lerman et al. 2009; Martin and Sharp 2004; Treister et al. 2004; Zelickson and Rogers 1986). Imatinib, a tyrosine-kinase inhibitor used for the treatment of several malignancies, including chronic myeloid leukemia and gastrointestinal stroma tumor (GIST) usually associated with skin hypopigmentation, may also cause skin and/or oral...
