Abstract
BACKGROUND: A vast number of conditions ranging from simple trauma to hereditary and collagen vascular disease had been described in association with acroosteolysis. OBJECTIVE: To demonstrate that severe cold exposure not mounting to frostbite may be associated with acroosteolysis. METHODS: A 16-year-old girl with acroosteolysis presenting with brachyonychia was fully investigated for possible cause of her nail and bone deformity. RESULTS: Lab investigations including Parathormone levels, Anti Scl 70, ANA, Anti-CCP and RF levels were all normal. X-ray imaging revealed resorption of the tufts of the terminal phalanges bilaterally. Disruption of nail fold capillaries with sluggish flow in capillary loops was evident on capillaroscopy. CONCLUSION: It had been repeatedly reported that frostbite, Raynaud's disease and diseases associated with repeated chilblains may be associated with secondary cold-induced acroosteolysis. Here, we present a case of acroosteolysis associated with brachyonychia following exposure to severe cold not mounting to frostbite.
