title: Lymphocele: a clinical analysis of 19 cases.
abstract: OBJECTIVE
  To summarize the clinical manifestations, diagnosis, and treatment of lymphocele.
  
  
  METHODS
  19 cases of lymphocele diagnosed by postoperative pathology from January 2003 to September 2012 were retrospectively analyzed, especially the general information, clinical manifestations, imaging, operations, and pathological findings.
  
  
  RESULTS
  In 19 cases, the common locations were in retroperitoneal, abdominal wall, and neck. There were no typical clinical manifestations with lymphocele. 6 cases visited hospital because of pain, while 13 cases were diagnosed incidentally with imaging or surgery. Fourteen cases undergoing CT were all displayed as cystic lesion. In 12 of 14 cases undergoing type-B ultrasonic, the masses were shown to be cystic lesion without special signs. 19 cases were all treated by surgical resection, and testified to be lymphocele with pathological analysis. The sensitivity of D2-40 was 89.5% (17/19) in our study.
  
  
  CONCLUSIONS
  Lymphocele is very rare with no specific clinical manifestations. The preoperative diagnosis was based on imaging examinations, while definite diagnosis was based on the pathological, and (or) immunohistochemical examination with D2-40. The prognosis of lymphocele is good after it is removed completely.
