Bi-acromial dimples: a series of seven cases.

Seven patients with bi-acromial dimples are reported, with a family history in only one. This skin condition presented as an anatomic peculiarity without associated abnormalities. Although it has been previously documented as a finding in malformation syndromes such as the 18q syndrome, we point out that it may be found quite frequently in isolation and without morbidity. Therefore, it should be mainly considered as an anatomic variation without pathologic significance.
