OBJECTIVE: To study the clinicopathologic characteristics, immunophenotypes, pathologic diagnosis and differential diagnosis of @entity72891 ( @entity1127 ). METHODS: The clinical data, histologic features and immunohistochemical results of 6 cases of @entity72891 were analyzed, with review of literature. RESULTS: There were altogether 5 @entity1 and a @entity1 . The age of @entity1 ranged from 44 to 87 years (median age = 61 years and mean age = 62 years). The sites of involvement included stomach (number = 2), jejunum (number = 2), distal ileum (number = 1) and rectum (number = 1). The @entity1 often presented with @entity490 or discomfort and tarry stool. All the cases studied showed similar morphology, were submucosa-based and composed of bland spindle cells associated with loose collagenous stroma and perivascular @entity4 . Prominent concentric fibroblastic proliferation ("onion-skin" appearance) and eosinophilic infiltrate were characteristics. Three of the @entity1 underwent surgical resection. The remaining @entity1 had the lesions removed with endoscopy. Follow-up data were available in 5 @entity1 and none of them had disease recurrence or @entity3 . CONCLUSIONS: @entity1127 is a rare @entity1820 . Correct diagnosis primarily relies on pathologic examination. It needs to be distinguished from @entity674 or @entity5 .
