Abstract

Filariasis caused by nematodes affects the structure and function of lymphatic vessels. Lymphedema due to lymphatic blockage and lymphadenitis is the usual mode of presentation of filariasis. However, rarely extralymphatic filariasis has been reported in uncommon sites, including skin and soft tissue. is the most common nematode causing extralymphatic filariasis. We report a rare case of a 25-year-old man with live extralymphatic filarial infestation presenting as a facial subcutaneous soft-tissue swelling confirmed by ultrasonography (USG), which revealed the filarial dance sign. Filariasis can present in many different ways and pose a significant dilemma for the clinician. It is essential to be aware of atypical presentations of filariasis for prompt diagnosis and further treatment.
