Prolonged administration of diphenylhydantoin (DPH) has been implicated as a possible etiologic factor in immunological aberrations and lymphoproliferative disorders. Diphenylhydantoin may account for the increase in susceptibility to lymphoproliferative diseases, as a result of its immunosuppressive effect. We report a case of amyloidosis with monoclonal gammopathy which developed during DPH treatment, without multiple myeloma or lymphoproliferative disorders. The association between DPH and monoclonal gammopathy is very rare, and such a case of amyloidosis associated with DPH has not been reported previously. DPH, however, may have played a role in the development of monoclonal gammopathy, which was the precursor of amyloid protein.

D009404	Nephrotic Syndrome	A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D010672	Phenytoin	An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.

D004834	Epilepsy, Post-Traumatic	Recurrent seizures causally related to CRANIOCEREBRAL TRAUMA. Seizure onset may be immediate but is typically delayed for several days after the injury and may not occur for up to two years. The majority of seizures have a focal onset that correlates clinically with the site of brain injury. Cerebral cortex injuries caused by a penetrating foreign object (CRANIOCEREBRAL TRAUMA, PENETRATING) are more likely than closed head injuries (HEAD INJURIES, CLOSED) to be associated with epilepsy. Concussive convulsions are nonepileptic phenomena that occur immediately after head injury and are characterized by tonic and clonic movements.
