Gamma heavy chain disease--presenting as pancytopenia and splenomegaly.
A patient with gamma heavy chain disease (Franklin's disease) was discovered during evaluation for pancytopenia and splenomegaly. Lymphadenopathy, palatal edema, and infiltration of the bone marrow palatal edema, and infiltration of the bone marrow with abnormal cells were all absent. Serum and urine protein electrophoresis demonstrated a monoclonal protein migrating in the beta region. Immunoelectrophoresis showed that it reacted with antibodies against the Fc fragment of IgG heavy chains (gamma chains) but not with antibodies against kappa and lambda but not with antibodies against kappa and lambda light chains of Fab fragments. In the first year after detection of the disease, the patient had acute cholecystitis and disseminated herpes zoster. Sixteen months after diagnosis he died of overwhelming pneumonia caused by Pseudomonas aeruginosa and lebsiella neumoniae. A striking feature of his illness was his asymptomatic presentation, with pancytophenia and splenomegaly the only indication of this disease.
