A nthrax is a zoonotic disease, which is caused by Bacillus anthracis, whose incidence is decreasing gradually in the world and is more common in underdeveloped countries. Anthrax is transmitted to humans through the cutaneous route by trauma that disrupts skin integrity, the lungs by inhalation, and the gastrointestinal tract by ingesting infected meats. Anthrax occurs in three clinical forms, depending on the route of infection: cutaneous, pulmonary, and gastrointestinal anthrax. Cutaneous anthrax accounts for 95% of anthrax cases. [1] Cutaneous anthrax is most commonly seen in the head, neck, and upper extremities, and although palpebral involvement is rare, it has an important place in eyelid complications. [2] Palpebral anthrax accounts for only 4% of anthrax cases. In cases of palpebral anthrax, complications such as cicatricial ectropion, eschar formation, and lagophthalmia may develop despite treatment. It has been reported that the prevalence of complications decreases with early diagnosis and appropriate antibiotic treatment. [2,3] Anthrax is a rare zoonotic disease in humans caused by Bacillus anthracis. The most common form of this disease is cutaneous anthrax. Rarely, eye involvement may occur. In this case, a nine-year-old male patient with anthrax on his left eyelids is presented. From the patient's history, it was learned that a slight papular reaction occurred on the left side of the eye, then the lesion enlarged within three days, and edema developed around the eye. On the fifth day of the patient's preseptal cellulitis diagnosis, progress in eye lesions and necrosis and eschar formation around the eyes were detected, while Bacillus anthracis polymerase chain reaction (PCR) positivity was detected on the fifth day of the patient's complaints. The patient was treated with ciprofloxacin and clindamycin and a clinical response was achieved. Anthrax should be kept in mind in the differential diagnosis of preseptal and orbital cellulitis, especially in patients who have close contact with animals. If palpebral anthrax is not treated effectively on time, it can leave scars on the eyelids and cause permanent deformities and loss of function. Early diagnosis and initiation of antibiotic therapy significantly reduce the occurrence of complications. In this case report, a pediatric case with eyelid anthrax, which is rarely seen in anthrax disease, is presented.
