Файл:Acroosteolysis- x-rays.png
Early changes of acroosteolysis can be detected by x-ray. In this radiograph there is dissolution and fragmentation of the bone in several of the terminal phalanges.~CDC

Acroosteolysis is resorption of the distal bony phalanges. Acroosteolysis has two patterns of resorption in adults: diffuse and bandlike.

The diffuse pattern of resorption has a widely diverse differential diagnosis which includes: pyknodysostosis, collagen vascular disease and vasculitis, Raynaud's neuropathy, trauma, epidermolysis bullosa, psoriasis, frostbite, sarcoidosis, hypertrophic osteoarthropathy, acromegaly, and advanced leprosy.[1][2][3]

The bandlike pattern of resorption may be seen with polyvinyl chloride exposure and Hadju-Cheney syndrome.[1]

A mnemonic commonly used for acro-osteolysis is PINCHFO.[4] Pyknodysostosis, Psoriasis, Injury (thermal burn, frostbite), Neuropathy (diabetes), Collagen vascular disease (scleroderma, Raynaud's), Hyperparathyroidism, Familial (Hadju-Cheney, progeria), Occupational (polyvinyl exposure),

Acroosteolysis may be associated with minimal skin changes or with ischemic skin lesions that may result in digital necrosis.[5]Шаблон:Rp
