Abstract：
Although actinomycosis is frequently seen in the cervicofacial region, it is very rare in the parotid gland. Furthermore, it can be confused with salivary gland malignancies in imaging. The most important underlying causes are cervicofacial trauma, tooth extraction history and poor oral hygiene. A 43-year-old male patient was admitted to otorhinolaryngology department with a complaint of progressive swelling on his cheek. The histopathological examination of fine-needle aspiration (FNA) biopsy showed acute suppurative polymorphous leukocytes and actinomycese hyphae balls within histiocytes. The patient was started on amoxicillin 2 gm per day for two months. With antibiotherapy, the swelling in the patient\'s parotid gland decreased and completely healed at the end of six months. Primary parotid actinomycosis has been rarely reported in the literature, differential diagnosis is usually problematic as both clinical and radiological findings may mimic parotid tumour; however, it can be useful to apply FNA cytology for a quick diagnosis and treatment.
摘要：
虽然放线菌病常见于颈面部，它在腮腺中非常罕见。此外，在影像学上可与唾液腺恶性肿瘤混淆.最重要的根本原因是颈面部外伤，拔牙史和口腔卫生差。一名43岁的男性患者因脸颊进行性肿胀而入院耳鼻喉科。细针穿刺活检（FNA）的组织病理学检查显示，组织细胞内有急性化脓性多形性白细胞和放线菌菌丝球。患者开始每天服用2克阿莫西林，持续两个月。通过抗生素治疗，患者腮腺肿胀减轻，并在6个月后完全愈合。原发性腮腺放线菌病在文献中鲜有报道,鉴别诊断通常是有问题的，因为临床和放射学发现都可能模拟腮腺肿瘤;然而，应用FNA细胞学检查可用于快速诊断和治疗。
