úlcera eosinófila de la mucosa oral

eosinophilic ulcer of the oral mucosa, an entity, poorly deciphers in world-wide literature. it is defined as a self-limited, benign injury that although it can appear in different areas of the buccal cavity it presents a noticeable predilection via the ventral mucosa of the tongue. clinically, one looks like an ulcer with hard and risen edges. the histo-pathological findings are typical and consist of a rich infiltrated mix of eosinophils, as well as a population of large mononuclear cells. recent reports based on immunohistochemical studies allow us to confirm the presence of large atypical lymphocytes cd30+ and therefore include this lesion injury in the spectrum of lympho proliferative disorder simulators. despite this the etiopathogenic mechanism remains unknown and local trauma still plays an unexplained roll; although the majority of publications have explained the phenomena as a reactive mechanism. the importance of this injury is established by its differential diagnostic because of its clinical similarity to spinocellular carcinoma, histoplasmosis, syphilitic chancre, ulcer tuberculosis, epidermoid carcinoma and others. in our work the literature is reviewed and clinical characteristics, histo-pathologies and alternative therapies are discussed. we use the case of a young patient who has a biopsy in an effort to diagnose with certainty has a relapse of the lesion which directs the treatment towards combined surgery and local intra lesion cortico therapy which led to successful remission.
