Abstract: To the Editor: I read with interest the article by Spencer et al on bilateral skin dimples of the shoulders (Pediatr Dermatol I993;10:I6-18). Although little has been written about this subject, I was under the impression that this finding is rare based on the available literature (1). However, since publication of my case (1) I have noted shoulder dimpling as an incidental finding in over 15 patients. In one series, a mother and daughter had single right shoulder acromial dimpling. Most of the patients reported a family history of dimpling on further questioning, again suggesting an autosomal dominant inheritance pattern. I have also seen numerous individuals (wearing temk tops) with shoulder dimpling while walking in public. Based on these observations I now believe that this is not an uncommon finding.
TL;DR: A term female neonate who was noted on routine new-born check to have bilateral symmetrical shoulder dimples was otherwise healthy, had normal range of shoulder movements and was not dysmorphic and on further assessment it transpired the father has the same bilateral shoulder dimple but was not aware of their existence.
Abstract: Congenital Acromial or Shoulder dimples are cutaneous depressions overlying the acromial process of the scapula. They are usually bilateral and symmetrical. Isolated biacromial dimples are usually benign and warrant no further investigations. Family history in an autosomal dominant pattern, as in our case, is frequently obtainable but the majority of isolated bilateral shoulder dimples are sporadic. There are few reports of syndromic associations as well as two cases of associated maternal cocaine abuse. Our case is a term female neonate who was noted on routine new-born check to have bilateral symmetrical shoulder dimples. She was otherwise healthy, had normal range of shoulder movements and was not dysmorphic. On further assessment it transpired the father has the same bilateral shoulder dimples but was not aware of their existence. No further investigations were carried out. This case add to the few reported cases of Biacromial Dimples with autosomal pattern of inheritance in an otherwise normal baby
