Acinetobacter baumannii orofacial cellulitis: report of 2 cases Publication date: June 2019 Source: Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, Volume 127, Issue 6 Author(s): Thaís dos Santos Fontes Pereira, Denise Vieira Travassos, Raissa Cristina Costa Silva, Laiz Fernandes Mendes Nunes, Maria Edileusa Santos, Célia Regina Lanza, Gabriela Assunção Goebel, Fabiana Maria Kakehasi, Tarcília Aparecida Silva Acinetobacter baumannii infection of skin and soft tissues is uncommon and usually associated with trauma. The present report describes 2 pediatric cases of cellulitis in the orofacial region, caused by A. baumanniiinfection with a fatal outcome. A 12-year-old male patient, diagnosed with acute promyelocytic leukemia, presented with an ulcerated lesion on the lip suggestive of local trauma. The condition progressed to cellulitis, epithelial necrosis, and nonspecific vesicles and blisters. The second case occurred in a 10-year-old male patient with a diagnosis of Burkitt lymphoma. The patient's condition progressed to World Health Organization Grade IV mucositis and cellulitis. In both cases, hemoculture was positive for multidrug-resistant A. baumannii. In conclusion, A. baumannii should be considered a potentially multidrug-resistant pathogen in the presence of skin and soft tissue cellulitis. Ulcerated oral lesions may place hospitalized pediatric patients at risk for A. baumannii infection.
