Background: Lymphedema is the chronic, progressive enlargement of tissue due to inadequate lymphatic function. Although lymphedema is a specific condition, patients with a large extremity are often labeled as having "lymphedema," regardless of the underlying cause. The purpose of this study was to characterize referrals to a center to determine if lymphedema should be managed by specialists.
Methods: Patients treated in our Lymphedema Program between 2009 and 2013 were reviewed. Diagnosis was determined based on history, physical examination, photographs, and imaging studies. Lymphedema type (primary or secondary), location of swelling, patient age, sex, and previous management were documented. The accuracy of referral diagnosis and the geographic origin of the patients also were analyzed.
Results: Two hundred twenty-five patients were referred with a diagnosis of "lymphedema"; 71% were women and 29% were children. Lymphedema was confirmed in 75% of the cohort: primary (49%) and secondary (51%). Twenty-five percent of patients labeled with "lymphedema" had another condition. Before referral 34% of patients with lymphedema received tests that are nondiagnostic for the disease, and 8% were given a diuretic which does not improve the condition. One third of patients resided outside our local referral area. The average time between onset of lymphedema and referral to our Lymphedema Program was 7.7 years (range, 1-59 years).
Conclusions: Patients presenting to a center with "lymphedema" often have another condition, and may be suboptimally managed before their referral. Patients with suspected lymphedema should be referred to specialists focused on this disease.
