title: [Clinical and pathological analysis of 151 cases of tumors in lacrimal fossa].
abstract: OBJECTIVE
  To investigate the clinical features and pathological classification of tumors in lacrimal fossa.
  
  
  METHODS
  A retrospective study of 151 cases of tumors in lacrimal fossa in recent 8 years from EENT hospital was performed to investigated the clinical features, histopathological classification and prognoses.
  
  
  RESULTS
  In 69 cases of benign lacrimal epithelial tumors, pleomorphic adenoma was the most common tumor (63 cases, 41.7%), followed by myoepithelioma (3 cases, 1.2%), lacrimal duct cyst (2 cases, 1.3%). In 34 cases of malignant lacrimal epithelial tumors, adenoid cystic carcinoma was the most common tumor (15 cases, 9.9%), followed by pleomorphic adenocarcinoma (14 cases, 9.3%), adenocarcinoma (4 cases, 2.6%). There were 48 cases of lacrimal non-epithelial lesions. Mucosa-associated lymphoid tissue (MALT) lymphoma was the most common tumor (17 cases, 11.3%), followed by pseudotumor (12 cases, 7.9%), benign lymphoepithelial lesion (7 cases, 4.0%).
  
  
  CONCLUSIONS
  There are a variety of tumors in lacrimal fossa. The treatment of pleomorphic adenoma and the diagnosis of MALT lymphoma are the most difficult tasks in present clinical work.
