title: Oral traumatic ulcerative granuloma with stromal eosinophilia: A clinicopathological study of 34 cases.
abstract: OBJECTIVE
  Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a special oral ulcerative lesion that shares many clinical features of an oral squamous cell carcinoma. This study reports the clinicopathological features of 34 oral TUGSE lesions in Taiwanese patients.
  
  
  METHODS
  Thirty-four TUGSE cases were retrieved from the files of the Department of Oral Pathology and Oral Diagnosis, National Taiwan University Hospital from 2003 to 2009. Their clinical data and histopathological features were examined, collected, and analyzed.
  
  
  RESULTS
  The study group included 22 male and 12 female patients (64.7% and 35.3%, respectively) with oral TUGSE. The mean age of the patients was 49 years (range, 8 to 80 years). The most common site for oral TUGSE lesions was the tongue (23 cases, 67.6%), followed by the buccal mucosa (6 cases, 17.6%), retromolar area (2 cases, 5.9%), floor of the mouth and lingual sulcus (2 cases, 5.9%), and lip (1 case, 3.0%). For 23 tongue cases, 19 occurred on the dorsum and the tip (82.6%) and 4 on the ventral surface (17.4%). Of the 34 oral TUGSE lesions, 13 (38.2%) had a mild, 11 (32.4%) a moderate, and 10 (29.4%) a severe eosinophilic infiltrate.
  
  
  CONCLUSIONS
  Oral TUGSE lesions occur more frequently on the dorsal surface and the tip of the tongue and in male patients between 41 and 60 years of age. The eosinophilic infiltrates in oral TUGSE lesions show a scattered or clustered pattern, and their density varies from case to case. Oral TUGSE is a self-limiting lesion, and aggressive surgical treatment is usually not required.
