Formerly a fatal condition. Wegener's granulomatosis is now treated wi
th good results. Clinical morbidity is often due to failure by clinici
ans to make the diagnosis. Many patients (including our cases reported
here) present with atypical symptoms, and only a high index of suspic
ion will ensure early diagnosis. Classical chest and renal symptoms of
ten indicate late stage disease. We present two cases that underline t
he limitations of current 'diagnostic' immunological tests whilst emph
asising the importance of clinical features in diagnosis. Standard tre
atment with Cytotoxic agents and corticosteroids are effective but car
ry considerable morbidity. We have followed the current trend of incor
porating a less toxic antibiotic agent in the management of this enigm
atic condition.
