Actinomyces lymphadenitis.

Actinomyces lymphadenitis. Proc (Bayl Univ Med Cent). 2020 Jul;33(3):444-445 Authors: Kim J, Wood C, Sandkovsky U, Rokadia H Abstract Actinomyces is a gram-positive anaerobe that colonizes the human oral cavity. Its pathogenesis involves the disruption of the mucosal membrane, leading to suppuration and subsequent abscess formation, most commonly in the cervicofacial region. The bacteria form masses consisting of aggregates of branching, filamentous bacilli. They typically spread by direct tissue invasion and less commonly through hematogenous spread. Lymphatic spread is extremely uncommon. To the best of our knowledge, only two cases have been reported with lymph node involvement. Clinically, lymphadenopathy associated with Actinomyces may be misinterpreted as malignancy, causing unnecessary surgical interventions when only antibiotics are warranted. This case highlights the importance of properly diagnosing a rare phenomenon of Actinomyces lymphadenitis. PMID: 32675981 [PubMed]
