title: Hereditary late-onset lymphedema.
abstract: Two different types of hereditary late-onset lymphedema are presented. In one family the father and one son had recurrent streptococcal lymphangitis beginning in childhood. In the son there was lymphatic hypoplasia in both legs with the infection having only occurred in one. Prophylaxis with penicillin prevented the recurrent lymphangitis. Because of 30 years of untreated lymphangitis, the father has chronic severe lymphedema. The second type, lymphedema associated with extra eyelashes (distichiasis) and a wide spinal canal, occurred in a woman whose lymphedema began at age 12 but in whom the hereditary nature of the disorder was not recognized until she was 29. Both of these types of late-onset lymphedema, lymphedema with lymphangitis and lymphedema with distichiasis, are due to autosomal dominant genes. Both families would have benefited from early diagnosis of the cause of the lymphedema.
