Band acro-osteolysis in a Black woman: a case report and review of the literature

Abstract

Acro-osteolysis is a bone resorption reaction that progresses slowly in the distal phalanx of the hand and foot and is associated with various diseases. It can be classified as idiopathic or secondary. Although the mechanism of acro-osteolysis has not been fully elucidated, the presence of a chronic ischemic injury appears to have a significant effect, and bone metabolism dysregulation due to the accompanying calcinosis or peripheral neuropathy also appears to contribute. Acro-osteolysis can show various clinical and radiological features, and the differential diagnosis of the underlying etiology is essential. It is a rare and sporadic disease worldwide. The authors experienced a case of acro-osteolysis suspected of idiopathic cause in a Black woman; therefore, we report this case with a literature review.
