Filariasis is a parasitic infectious disease caused by filarial nematode worms. These worms mainly dwell in subcutaneous tissues and lymphatics of the human host, with a predilection for lower limbs, retroperitoneal tissues, spermatic cord, and epididymis. Oral or perioral involvement of the filarial nematode is rare. This case report describes a filarial abscess in the right submandibular region. Fine needle aspiration cytology of the abscess revealed the presence of microfilaria of Wuchereria bancrofti species. The parasite was also present in the peripheral blood smear. Filarial infection presenting in this region is unusual and can cause diagnostic dilemma. The clinician can consider filariasis as one of the differential diagnosis while treating those abscesses in the orofacial region that are unresponsive to routine management, especially, patients hailing from endemic areas.
丝虫病是由丝虫线虫引起的一种寄生虫感染性疾病。这些蠕虫主要寄居于人类宿主的皮下组织和淋巴管，以下肢、腹膜后组织、精索和附睾为好发部位。丝虫线虫累及口腔或口周的情况罕见。本病例报告描述了一例右下颌下区的丝虫性脓肿。脓肿的细针穿刺细胞学检查显示存在班氏吴策线虫微丝蚴。外周血涂片也发现了该寄生虫。在这个部位出现丝虫感染并不常见，可能导致诊断困境。对于口面部区域常规治疗无效的脓肿患者，尤其是来自流行地区的患者，临床医生在治疗时可将丝虫病列为鉴别诊断之一。
