acroosteolysis

ac·ro·os·te·ol·y·sis

(ak'rō-os-tē-ol'i-sis), [MIM*102400]
Congenital condition manifested by palmar and plantar ulcerating lesions with osteolysis involving distal phalanges of the fingers and toes. Acquired acroosteolysis has been reported in workers exposed to vinyl chloride. There is an autosomal disorder, Cheney syndrome [MIM*102500], in which this finding is combined with sutural (wormian) bones, hypoplasia of the mandibular rami, and basilar osteoporosis.
See also: Cheney syndrome.

[ak′rō·os′tē·ol′isis]
destruction of the digit tips, including the bone, usually caused by vasospasm. It is characterized by Raynaud's phenomenon, loss of bone tissue in the hands, and sensitivity to cold temperatures. Causes include scleroderma, Raynaud's disease, Buerger's disease, frostbite, and exposure to vinyl chloride.
