In a report published in the medical journal BMJ Case Reports, doctors described how a 60-year-old Japanese woman started taking her prescribed medication and then saw her tongue turn black and hairy.
About 14 months ago, the woman was diagnosed with rectal cancer and started chemotherapy.
Doctors prescribed her minocycline, an antibiotic that was supposed to help her body fight the harmful effects of chemotherapy. At first it seemed to help, but after a while, the Japanese woman noticed that her tongue was covered with tiny black dots and growths that looked like hair.
After the examination, doctors diagnosed the woman with chronic hypertrophy of the filiform papillae, a disease that causes the appearance of large bumps on the tongue.
In patients with geographic tongue, hard, filiform papillae grow on the surface of the tongue. This disease is acquired, caused by taking a prescribed antibiotic. Lenta.ru .
