acute blue finger syndrome: a case report

Acute blue finger syndrome is a rare benign condition with an unknown etiology. it predominantly affects middle-agedfemales and may be associated with pain, itching, or a burning sensation. the bluish discoloration is usually idiopathic, and it is necessary to rule out other causes of blue fingers. the syndrome is a diagnosis of exclusion and has a good prognosis. the sudden color change can lead to patient anxiety, but the physician’s insight regarding the benign nature can alleviate unnecessary distress. we present the case of an adult female with bluish discoloration of the proximal phalanx of the left index finger, which was sudden in onset and asymptomatic. following a thorough history and workup, the patient was counseled, and on follow-up, a spontaneous resolution was observed. we intend to report this case due to the rarity of blue finger syndrome as well as to highlight the significance of its benign nature and spontaneous resolution.
