Thrombangiitis obliterans (Buerger disease) is a rare vascular disease, cha
racterized by a multilocular, segmental, non-arteriosclerotic, thrombotic i
nflammation of small and medium size arterial and venous vessels and nerves
. The precise etiology is unknown, but there is a cause-effect relationship
with tobacco smoking. Autoimmunological, immunogenetical, infectious and h
emostatic processes have been discussed as pathogenetic factors. The clinic
al picture is typically characterized by acrally localized, non-healing ulc
erations, which frequently prompt patients to see a dermatologist. We prese
nt two patients with thromboangiitis obliterans and discuss the clinical fe
atures, the resulting differential diagnostic spectrum and possible therape
utic approaches.
