A 66-year-old male traveller returning from Costa Rica presented with a 4-week history of a gradually enlarging painless boil above the lateral malleolus of his right ankle. He was systemically well, and had no recollection of an insect bite. Examination revealed a 2 cm furuncle (fig 1A) with two central pores. When occluded, a breathing tube extended through the larger pore.
