Summary Tophi develop during the most advanced clinical stage of gout, and are usually located on or around the joints. However, unusual skin features caused by intradermal and/or subcutaneous deposition of tophaceous material at locations other than articular regions have been reported. We present the case of a patient with a condition that has been recently termed ‘miliarial gout’. which is only the second such case, to our knowledge. A 51‐year‐old woman, who had a chronic joint disease that had been diagnosed and treated as psoriatic arthritis, presented with multiple asymptomatic, yellowish‐white, firm papules (1–3 mm in size) on erythematous areas on the outside of her left leg. On histological examination of a skin biopsy, uric acid crystals were seen in the dermis and subcutis. The patient also had a raised level of serum urate, consistent with a diagnosis of gout. Treatment with allopurinol led to rapid improvement. Intake of corticosteroids and diuretics was a possible triggering factor for the development of cutaneous tophi in this patient.
