A Woman with Multiple Joint Dislocations

 

Am Fam Physician. 2018 May 15;97(10):673-674.

A 65-year-old woman was admitted to the hospital with a left elbow fracture after a fall. She had a history of recurrent joint dislocations since childhood and orthopedic procedures on several joints. When she was younger, she could rest her palms on the floor in a standing position while flexing the trunk forward with knees fully extended.

On physical examination, the patient was in no acute distress other than pain in her elbow. She could touch her forearm with passive flexion of her right thumb. Hyperelasticity of the skin (Figure 1) was noted.

Question

Based on the patient's history and physical examination findings, which one of the following is the most likely diagnosis?

A. Cutis laxa.

B. Ehlers-Danlos syndrome.

C. Elastoderma.

D. Pseudoxanthoma elasticum.

Discussion

The answer is B: Ehlers-Danlos syndrome. This syndrome encompasses a group of distinct inherited connective tissue disorders.1 Marked skin hyperelasticity, widened cutaneous atrophic scars, and generalized joint hypermobility are features of classic Ehlers-Danlos syndrome. Easy bruising, subcutaneous spheroids, and molluscoid pseudotumors may also occur.

In the vascular form of Ehlers-Danlos syndrome, the skin is thin and translucent with visible underlying vessels, but not hyperelastic. Possible complications of vascular Ehlers-Danlos syndrome include aortic dissection, rupture, and aneurysms.2 Other forms of the syndrome are hypermobile, kyphoscoliotic, arthrochalasic, cardiovalvular, myopathic, periodontal, musculocontractural, dermatosparactic, and brittle cornea syndrome. Kyphoscoliotic Ehlers-Danlos syndrome is an autosomal recessive condition, whereas the other forms are autosomal dominant.
