A 56-year-old female was referred to King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, with central corneal thinning in her left eye and a scar. She reported a painless decrease in vision following the self-application of alum substances to her left eye for eye redness and discomfort. There was no history of previous trauma, surgery, or any ophthalmic disorder. There was no history of any systemic illness or use of any systemic or topical medications. Ophthalmic examination indicated the best-corrected visual acuity of 20/20 in the right eye (OD) and counting fingers at 1 m in the left eye (OS). Intraocular pressure measured with applanation tonometry was within the normal range bilaterally. Examination of the right eye was unremarkable except for a mild cataract. Slit-lamp examination of the left eye indicated a quiet conjunctiva and central corneal scar with no corneal epithelial defect; there was corneal thinning without descemetocele, nuclear sclerosis, and a hazy view of the fundus []. B-scan ultrasonography OS indicated no pathology at the posterior pole. The alum substance was analyzed using scanning electron microscope (SEM) and revealed the elements shown in .
A 55-year-old Pakistani female with metastatic melanoma underwent branding with a metal rod heated over coal to multiple sites of cutaneous metastases including the right ear, angle of the mandible, middle of the neck and left axillary area (Figure ). The metallic ash was then rubbed onto the resulting wounds. Three days later she presented with fever, tachycardia and hypotension. Physical examination revealed multiple circular full-thickness burns and blisters with central sparing ranging in size from 1 to 6 cm in diameter. The burn margins were erythematous and indurated. Aggressive management of her burns was performed on an inpatient basis. Broad-spectrum oral antibiotics were administered and the wound was treated with topical silver sulfadiazine and clean dressings. Since normal skin acts as a defense mechanism in the body, in our patient, who was already immunocompromised, branding created third degree burns and breached the intact skin seeding the metastatic lesions with infection. Blood and wound cultures grew the same Staphylococcus aureus. She was started on intravenous vancomycin and levofloxacin. Despite aggressive measures, she died in the hospital a week later. Thus, it was either inflicting third degree burn wounds in our immunocompromised patient, or wound contamination due to unsterile techniques that had led to complications in our patient, or a combination of both.
