Abstract:
We describe two patients, aged 70 and 71, respectively, with poststreptococcal erythema nodosum and arthritis. The arthritis affected the ankles in both patients and the knees in one of them. In view of the pronounced erythema nodosum in both patients, the arthritis is considered as an associated symptom of poststreptococcal erythema nodosum. Therefore, this is an example of a third variant of poststreptococcal arthritis, in addition to rheumatic fever and poststreptococcal reactive arthritis. This type of arthritis can be seen even in the geriatric population.
