Clinical pathologic conference case 4: Just an extravasation mucocele?

Abstract

In 2007, a 58-year-old man sought medical attention for soreness of his mouth. He first experienced problems 1 year earlier when he used an inhaler for a chest infection and this apparently led to thrush, which was treated and resolved. Since then, his mouth had been intermittently sore. He described development of raised white areas on the lower lip mucosa, which might have been blisters or ulcers, which burst after half a day. His upper and lower lips and tongue had been particularly sore. He found it impossible to eat anything with any flavour in it and had difficulty using toothpaste. A similar subsequent lip lesion is shown in Figure 1.
