Introduction

|---|
A 60-yr-old man presented with a 15-yr history of episodic,
inflammatory polyarthritis with subcutaneous tophi over the
left elbow. He was diagnosed with polyarticular gout after gouty
crystals were demonstrated from joint fluid. He was treated
with colchicine and allopurinol. He was seen after 1 month when
he complained of the spontaneous development of multiple intradermal
bullae over the lateral and medial aspects of the feet, heels
and in the skin overlying the tendoachillis (
Fig. 1; see also
supplementary Figs 2 and 3 available at
Rheumatology Online).
The deposits were mildly painful and yellowish white without
signs of inflammation. Aspiration from the deposits revealed
chalky fluid containing needle-shaped crystals. The patient
was diagnosed as tophaceous gout with bullous tophi.
Tophi are usually firm nodular subcutaneous deposits, but may
rarely be intradermal pustules or plaques. Tophi presenting
as superficial bullae have only once been reported in the English
literature [
1]. That case was precipitated by a burn causing
local tissue injury in one patient. In our patient, the tophi
presented as intradermal bullae only on the margins of the sole
and heel. Since acute or repetitive trauma is a known precipitating
factor of gouty attacks, it could be postulated that imperceptible
trauma to the feet precipitated the tophaceous bullae. The skin
deposits did not invite the inflammatory response, possibly
because the patient was on colchicine.
The authors have declared no conflicts of interest.
