Steatocystoma multiplex is a condition characterized by numerous skin cysts that tend to develop during puberty. Cysts most often develop on the chest, upper arms and face, but may develop all over the body in some cases. The cysts may become inflamed and cause scarring when they heal. The condition can be caused by mutations in the KRT17 gene and is inherited in an autosomal dominant manner. Some cases are sporadic (where there are no other cases in the family). Some researchers have suggested that the condition may be a mild variant of pachyonychia congenita type 2. Treatment may include minor surgery to remove cysts and oral antibiotics or oral isotretinoin to reduce inflammation.
