Review of isolated ascending aortitis: differential diagnosis, including syphilitic, Takayasu's and giant cell aortitis.
The image of tree-barking and proximal aortic root dilatation is firmly entrenched in the minds of practising pathologists as representing syphilis until proven otherwise. We discuss the differential diagnosis of syphilitic aortitis, Takayasu's disease, and giant cell aortitis, with a review of the literature and brief overview of other types of aortitis. As a starting point, we report a case of non-specific, or idiopathic, aortitis with aneurysm that was initially misdiagnosed as syphilitic aortitis. ⋯ It is still unclear if there are histological features that separate Takayasu's disease and giant cell arteritis. In the majority of patients presenting with aortic root aneurysms, aortitis is an isolated finding not associated with autoimmune disease. Despite a plethora of literature, a histological classification of aortitis has yet to be attempted.

To determine the frequency of anaphylactic deaths amongst coronial autopsy cases performed in the greater Auckland region from 1985 to 2005, and review the circumstances of death and autopsy findings. ⋯ Anaphylactic reaction is an uncommon cause of sudden death. In many cases, no specific macroscopic or microscopic findings were detected at autopsy. In the presence of a typical clinical history, postmortem measurement of serum tryptase levels can be a useful diagnostic aid.
