Abstract

Introduction: Purpuras are red lesions with variable shades depending on evolution, determined by localized extravasation phenomena in the skin or mucosa; semiologically polymorphic and diffe-rentiated into thrombocytopenic and non-thrombocytopenic according to their pathophysiology. Ob-jective: To present a clinical case of non-thrombocytopenic oral purpura and probably exacerbated by the patient’s metabolic condition. Case report: A 51-year-old woman, partially edentulous and treated with metformin due to a diagnosis of type II diabetes mellitus, who registered non-palpa-ble red-purple lesions, vitro-pressure negative, compatible with petechiae and vibeces, distributed on the floor of the mouth, ventral face and lateral surfaces of the tongue associated with chronic trauma.

A histopathological study is required to confirm
