Abstract:
Digital gangrene due to arterial thrombosis can occur due to a variety of causes. There have been reports of patients who have presented with digital gangrene with no known predisposing factors, but with positive anti-centromere antibodies (ACA). Despite that they did not have features suggestive of disorders like Scleroderma or CREST syndrome. We report a patient with digital gangrene, who was asymptomatic before this episode and was found to have both ACA positivity and Polycythemia Vera.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
