Pigmented lesions of the oral cavity are important entities. The wide range of their clinical differential diagnosis includes such diverse systemic conditions as Addison's disease, Peutz-Jeghers syndrome, malignant melanoma, Kaposi's sarcoma, as well as specific oral lesions, such as amalgam tattoo or gingival melanosis. This paper reports a very rare cause of oral pigmentation, a melanic type, related to the use of Premarin.
