Abstract
Objectives
We aimed to clarify whether acute lipodermatosclerosis (LDS) progress to chronic LDS without continued compression therapy.
Methods
Between April 2015 and November 2021, 30 patients with acute/subacute LDS, which was diagnosed clinically by presence of isolated, poorly demarcated, tender erythema, and induration limited to the lower leg(s), visited our clinic and were able to be followed up for longer than a year. We reviewed their treatment results and the post-treatment courses.
Results
In all cases, the symptoms in the acute phase subsided with compression bandages. After the discontinuation of compression therapy, 18 legs (56%) progressed to chronic LDS, and 14 legs (44%) did not. In the legs without progression, subcutaneous tissue in the affected leg was thicker compared with that in the contralateral leg (median 19.1 mm vs. 13.4 mm, p < 0.05) on the initial visit. In the legs with progression, the difference in subcutaneous tissue thickness between the affected and unaffected legs was not significant (10.0 mm vs. 7.6 mm).
Conclusions
Our findings suggest that in legs which later progress to chronic LDS, subcutaneous tissue contraction due to panniculitis is already present during the acute phase; therefore, long-term compression therapy is unlikely to improve the prognosis.
