Actinomycosis is a rare chronic infectious disease, most commonly affecting the cervicofacial, pulmonary, or genitourinary areas. It is caused by the Actinomyces spp. bacteria, which are facultative anaerobes and gram-positive, nonsporing rods. The disease ischaracterized by the formation of cold abscesses or fistulas, as well as granulomatous tissue, reactive fibrosis, and necrosis, which can resemble local malignancy. Cutaneous actinomycosis in the trunk or extremities is extremely rare and is usually related to previous surgical procedures or trauma. However, we report one such rare case of cutaneous actinomycosis of the forearm without previous precipitating factors, which was successfully treated with prolonged antibiotherapy.
放线菌病是一种罕见的慢性感染性疾病，最常累及头颈部、肺部或泌尿生殖系统。它由放线菌属细菌引起，这些细菌是兼性厌氧菌，为革兰氏阳性、无芽孢杆菌。该疾病的特征是形成冷脓肿或瘘管，以及肉芽肿组织、反应性纤维化和坏死，这些表现可能类似于局部恶性肿瘤。躯干或四肢的皮肤放线菌病极为罕见，通常与先前的外科手术或创伤有关。然而，我们报告了一例无前驱诱发因素的前臂皮肤放线菌病罕见病例，该病例通过延长抗生素治疗成功治愈。
