Úlcera eosinofílica linguala propósito de un caso clínico

Resumo

Introduction: The eosinophilic ulcer is a rare benign lesion of the oral mucosa. It is known for its rapid onset and chronic course. Due to its main location, the tongue, clinical features and its slowhealing process, a differential diagnosis with oral squamous cell carcinoma is necessary. It is suggested that it is caused by local trauma, yet it is missing in half of the cases. The histopathological findings include dense polymorphic inflammatory infiltrate, with large eosinophils. Objective: We aim to report a case of eosinophilic ulcer and an updated literature review to analyse its etiological factors and treatment options. Case report: We present a case of a 75-year-old woman, with a painful ulcer in the right border of the tongue, which appeared 4 months ago. It had a diameter of 1 cm. In a period of 3 months, it had been biopsied twice, due to its recurrence. Both histological findings confirm the presence of a dense polymorphic inflammatory infiltrate, epithelial dysplasia and no neoplastic evidence. Afterwards, the lesion was treated with topical application of triamcinolone acetonide 0.5% and it healed within 3 months. Conclusion: Eosinophilic ulcer has an undetermined etiopathogenesis. Trauma is considered as a contributing factor. Biopsy is the best approach for diagnosis and treatment. Although with no clear evidence, the application of topical corticosteroids improves lesion development and symptoms.
