title: Concurrent familial myeloma in Northern Ireland.
abstract: Three families are presented containing two members of each family with myeloma over a 13-year period in Northern Ireland. In all three families, the disease was concurrent, and the first reported cases of concurrent myeloma in a father and son and also identical twins are included. This incidence represents a greater frequency than would be expected and gives credence to the idea of an etiologic agent in this disease.
