title: Pyrexia of unknown origin: an approach to diagnosis and management.
abstract: Fever of unknown origin is one of the supreme diagnostic challenges in medicine. Most cases are caused by common problems presenting in unusual ways. Infections account for 40%, neoplasms 20% and collagen vascular diseases 15% of cases. Repeated clinical evaluation and individualization in planning investigative procedures are the keys to early diagnosis. Several possible causes of pyrexia are discussed.
