放线菌属和丙酸蛛是生长缓慢的革兰氏阳性细菌，是正常口腔植物群的一部分。显微镜下，它们具有丝状结构，使它们具有真菌样外观。由这些细菌引起的感染被称为放线菌病。颈面部放线菌病通常是无痛的，生长缓慢，坚硬的肿块，可产生皮肤瘘，一种通常称为舌颌的疾病。较少见的是，面颈部放线菌病是一种急性的、压痛的、波动的肿块，提示急性化脓性感染。1 -4以下是3例面颈部放线菌病的儿科病例。2例下颌骨骨髓炎和下颌旁脓肿，均表现为急性木质肿块，无全身性疾病。
Actinomyces species and Arachnia propionica are slow-growing, Gram-positive bacteria which are part of the normal oral flora. Microscopically, they have a filamentous structure which gives them a fungus-like appearance. Infections caused by these bacteria are termed actinomycosis. Cervicofacial actinomycoses are usually painless, slow-growing, hard masses which can produce cutaneous fistulas, a condition commonly known as lumpy jaw. Less frequently, cervicofacial actinomycosis is an acute, tender, fluctuant mass suggestive of an acute pyogenic infection.1-4 Following are three pediatric cases of cervicofacial actinomycosis. Two cases, one of mandibular osteomyelitis and one of a paramandibular abscess, both occurred aytpically as acute woody masses without systemic illness.
