Eosinophilic ulcer of the oral mucosa: a case report
Eosinophilic ulcer of the oral mucosa is considered to be a benign, reactive, and self-limiting lesion, with unclear pathogenesis, manifesting as a rapidly developing solitary ulcer.

Published in the National Journal of Maxillofacial Surgery, the authors report a case of a 42-year-old man who presented with a chronic indurated ulcer of buccal mucosa adjacent to the right upper wisdom tooth.

Histopathological examination showed polymorphic inflammatory infiltrate, rich in eosinophilis, involving the superficial mucosa, and the deeper muscle layer. Immunohistochemical analysis revealed single CD30+ cells scattered within an inflammatory infiltrate.

The lesion was excised, and healing was uneventful with no recurrence in more than a year.
