Rationale:
- Other types of arthritis may be accompanied by subcutaneous nodules, most commonly rheumatoid arthritis, sarcoidosis, and
osteoarthritis. Other entities that may produce subcutaneous nodules and should be distinguished from gout include rheumatic
fever, chloromas, erythema nodosum, panniculitis, metastatic tumors, lupus profundus, and foreign bodies or foreign substances
injected under the skin.

Evidence:
- Some patients have tophi as the presenting physical finding. This finding may be peculiar to elderly women taking diuretics
in whom tophi may develop in the Heberden's nodes (osteoarthritis of distal interphalangeal joint) or finger pads (29; 30).
