Diagnosis


This patient has micrognathia, arthropathy of terminal interphalangeal joints and a past history of maculopapular rash (lesion) caused by Still’s disease (aetiology).


Notes



• The classic triad of Still’s disease is fever, oligoarticular arthritis and an evanescent salmon-coloured rash (which typically appears with the fever spikes), although the rash is persistent in up to one-third of patients.


• A sore throat is characteristic.


• Elevated ferritin levels, leukocyte counts, serum liver enzyme, and ESR are common.


• Still’s disease usually occurs in patients younger than 35 years of age.
