TEMPI syndrome

Signs and symptoms

The patients were all diagnosed at middle age. A monoclonal gammopathy was implicated in all patients tested.

Cause

The cause of the syndrome is unknown. Abnormal plasma-cell clone and monoclonal gammopathy are suggested to be triggers of the disease.

Diagnosis

The diagnosis is based on the five characteristics described above.

Treatment

Complete and partial disappearance of the symptoms of the TEMPI syndrome was reported with the drugs bortezomib, daratumumab and autologous stem cell transplantation.

History

In 2010, the case of a man with unexplained erythrocytosis and perinephric fluid collection as main features was described in the Case Records of the Massachusetts General Hospital.
