Buerger’s Disease
The histopathological findings vary according to the duration of the disease. The findings are most likely to be diagnostic in the acute phase of the disease
The hallmark of the acute-phase lesion is an occlusive, highly cellular, inflammatory thrombus, with less inflammation in the walls of the blood vessels. Polymorphonuclear leukocytes, microabscesses, and multinucleated giant cells may be present

First reported by von Viniwalter in 1879 but first detailed description in 1908 by Leo Buerger.
