Rheumatoid necroses in the forefoot.

BACKGROUND

The incidence and morphological features of rheumatoid necroses (RN) in the forefoot are unknown.

METHODS

Biopsy material from 223 patients with seropositive rheumatoid arthritis (RA) was examined morphologically. The incidence and morphological features of RN in the forefoot were evaluated.

RESULTS

RN was found in 65% of cases, which had not been suspected clinically. It was correlated with pain in 69% of cases.

CONCLUSIONS

Rheumatoid necrosis contributes to the development of pain and foot deformation. It can be a significant factor worsening the clinical behavior in seropositive RA patients.
