Resumo

To the Editor: A 17-year-old Italian male with Down syndrome presented to the dermatology department with a 2-cm ulcerative lesion on the right tip of his tongue (Fig 1). The onset was about 7 days earlier with mild swelling. The patient's parents described a persistent vesicular eruption in the same area during the previous 2 months. They attributed it to biting and self-inflicted injuries and treated it with multiple but inefficacious drugs (nystatin, metisoprinol, diflucortolone, and chloramphenicol). The physical examination revealed that the right submandibular lymph nodes were slightly enlarged and tender. Fever and malaise were not reported, and neither were any other symptoms. Routine hematologic parameters were normal, apart from a chronic low leukocyte count. These findings were similar to his previous laboratory examinations. His medical history, as reported by the parents, was negative for any kind of recurrent infection. He was otherwise in good health and had never been institutionalized. An HIV test was negative. An oral swab revealed significant growth of multiple anaerobic bacteria. Cancrum oris was strongly suspected, and a 3-mm punch biopsy of the lesion was performed. Histologic examination revealed a nonspecific acute process characterized by a heavy inflammatory infiltrate mainly comprised of neutrophilic abscesses and blood vessel endothelial swelling, suggestive of bacterial infection. As indicated by microorganism culture and sensitivity tests, an intramuscular dose of lyncomicin 600 mg (2 mL) twice per day was initiated, along with oral doses of multivitamin supplements. Dequalinium chloride was applied topically three times per day. After 10 days, the oral lesion was dramatically improved and the ulceration had almost completely resolved (Fig 2).Fig 2After 10 days of antibiotic therapy, the patient experienced dramatic improvement.View Large Image Figure ViewerDownload Hi-res image Download (PPT)Cancrum oris, also known as noma, is an acute gangrenous stomatitis that may affect the oral mucosa, the labiomental, and/or the labiomaxillary structures.
