Pelvic lymphocysts occur infrequently after radical surgery for cervical cancer. The problem is one of recognition. In a retrospective analysis of patients seen over 10 years in this department, the incidence was 25.3%. All were diagnosed by bimanual, clinical examination only. The only factor that appears to relate to the formation of lymphocysts is the presence of poorly differentiated tumors; 70.8% of patients developing lymphocysts had poorly differentiated tumors. All the lymphocysts in this series resolved spontaneously and did not produce any major complications.
