Lingua villosa nigra.

In March, 2010, a 53-year-old woman developed a black discolouration of her tongue. 4 weeks before developing the discolouration, she had had elective gynaecological surgery, from which she was recovering as an inpatient under our care. She did not smoke, but had a high intake of caff einated drinks, including six cups of tea and two cups of coff ee each day. During the course of her hospital stay she completed a 3-week course of amoxicillin clavulanate and metronidazole for a suspected postoperative pelvic infection. Tongue scrapings confi rmed Candida infection, and we diagnosed our patient with lingua villosa nigra (black hairy tongue) caused by a Candida infection
