Eosinophilic ulcer of the oral mucosa (also known as eosinophilic ulcer of the tongue, Riga–Fede disease, and traumatic eosinophilic granuloma) is a condition characterized by an ulcer with an indurated and elevated border. The lesion might be tender, fast-growing and the patient often not be aware of any trauma in the area.

Definition
Traumatic eosinophilic granuloma of the tongue (TEGT) is a reactive condition that commonly occurs on the ventral tongue.
Causes
It is often associated with trauma. However, other causes are suspected, such as drugs, inherent predisposition, immune reaction, or lymphoproliferative disorder.
Differential Diagnosis
Squamous Cell Carcinoma, Pyogenic granulomas, Lesions of a chronic granulomatous disease and Mesenchymal tumors
Treatment
When the lesion is excised, recurrence often occurs. Palliative care with nonsteroidal anti-inflammatory drugs (NSAIDs) may be used, and topical steroids can be curative. If the lesion does not respond to treatment, biopsy is required.
