Nail discoloration in a child with brucellosis

Brucellosis is a frequent zoonotic disease. During the course of brucellosis treatment, antibiotics can result in side effects. Nail discoloration due to doxycycline is a rare, benign, and self-limited presentation. It is important to recognize it in patients on antibiotic therapy in order to prevent overdiagnosis and unnecessary laboratory tests. Here, a case of an 11-year-old boy with nail discoloration during brucellosis treatment was presented.
