Brain abscess caused by Enterococcus faecalis following a dental procedure in a patient with hereditary hemorrhagic telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is a disease characterized by arteriovenous malformations (AVMs). Brain abscess is a complication of HHT with AVMs. Literature provides evidence that Enterococcus faecalis can cause endodontic infections. We present the case of an HHT patient who developed brain abscess due to E. faecalis after a dental procedure.

Cutaneous polyarteritis nodosa in adult onset Still's disease.

Adult onset Still's disease (AOSD) is a well recognized clinical disorder characterized by a typical rash. However, there have been several atypical cutaneous findings reported in patients with AOSD. Cutaneous polyarteritis nodosa (PAN) is a necrotizing vasculitis of the small and medium sized arteries, distinguishing itself from systemic PAN by its restriction to the skin and to the neurological and osteo-muscular systems. We report the case of a patient with AOSD who is unique in having developed cutaneous polyarteritis nodosa (PAN) during the active phase of her disease. To the best of our knowledge, no previous cases of AOSD associated with a cutaneous variant of PAN have been reported.
