Herpes zoster infection of the chest wall and the syndrome of inappropriate antidiuretic hormone secretion.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) can result from diverse conditions. There have been only two published reports linking this syndrome with herpes zoster infections--one disseminated and the other confined to the chest wall. We have reported a case in which herpes zoster infection of the chest wall probably precipitated the development of this syndrome.
