Acrosclerosis in Sarcoidosis.

Areas of sclerosis in the phalanges, particularly the terminal phalanges, are common in sarcoidosis despite the rarity of osteosclerotic changes in other bones. Of 37 patients with sarcoidosis with osseous changes of the hands or feet, 20 (54%) has sclerosis either alone or in combination with bone destruction. Of 48 patients with acrosclerosis, 20 (40%) had sarcoidosis. In the authors' experience with a largely black population, sarcoidosis was found to be the most common causes of acrosclerosis.
