Summary
Sarcoidosis frequently causes bone sclerosis in the phalanges, often mimicking acrosclerosis. This study found sarcoidosis to be a common cause of acrosclerosis, especially in Black populations.
Area of Science:
- Rheumatology
- Radiology
- Dermatology
Background:
- Bone sclerosis in the phalanges is a known manifestation of sarcoidosis.
- Osteosclerotic changes are rare in other bones in sarcoidosis patients.
- Acrosclerosis is a condition characterized by sclerosis of the distal extremities.
Purpose of the Study:
- To investigate the prevalence of phalangeal sclerosis in patients with sarcoidosis.
- To determine the frequency of sarcoidosis in patients diagnosed with acrosclerosis.
- To identify sarcoidosis as a potential cause of acrosclerosis.
Main Methods:
- Retrospective review of patients with osseous changes in hands or feet due to sarcoidosis.
- Analysis of patients diagnosed with acrosclerosis to identify underlying sarcoidosis.
- Evaluation of patient demographics, focusing on a predominantly Black population.
Main Results:
- Sclerosis was present in 54% of sarcoidosis patients with osseous hand/foot changes.
- Sarcoidosis was identified in 40% of patients with acrosclerosis.
- Sarcoidosis was the most common cause of acrosclerosis in the studied population.
Conclusions:
- Phalangeal sclerosis is a common finding in sarcoidosis.
- Sarcoidosis should be considered in the differential diagnosis of acrosclerosis.
- The association between sarcoidosis and acrosclerosis is significant, particularly in specific populations.
