Secondary pseudoainhum in a patient with Turner syndrome.

Secondary pseudoainhum is an autoamputation that develops in individuals aged approximately 20 to 50 years and is caused by diseases such as keratodermas, trauma, or congenital factors. The authors report a novel case of secondary pseudoainhum in a patient with Turner syndrome (45,X) who presented with bandlike constrictions in the toes bilaterally. To the authors' knowledge, secondary pseudoainhum has not been reported to be associated with Turner syndrome. However, physicians should be aware of this potentially deforming disease in patients with Turner syndrome.
