de Quervian tenosynovitis
- Due to thickening and stenosis of the synovial sheath from chronic overuse of the wrist or hand, trauma or repetitive activity
- pain on the radial side of the wrist and positive Finklestien maneuver.
Diagnose adult-onset Still disease
Quotidian fever, evanescent rash, arthritis, and multisystem involvement.
Diagnosis is based on typical clinical presentation with exclusion of infection and malignancy, particularly leukemia and lymphoma.
Laboratory abnormalities in patients with leukocytosis, anemia, thrombocytosis, elevated erythrocyte sedimentation rate, elevated serum ferritin level (≥1000 ng/mL [1000 µg/L]), and abnormal liver chemistry tests; antinuclear antibodies and rheumatoid factor typically are negative.
Diagnose Löfgren syndrome.

Henoch-Schönlein purpura
purpuric rash predominantly affecting** the distal lower extremities, arthritis, **abdominal pain, and hematuria.** Skin biopsy specimens reveal the presence of leukocytoclastic **vasculitis with deposits of IgA.** Kidney biopsies obtained in patients with persistent hematuria and proteinuria or kidney disease following an attack reveal a **glomerulonephritis with IgA deposition consistent with lesions seen in IgA nephropathy
