Abstract: Dirofilariasis is a zoonotic parasitic infection caused by filarial nematodes of the genus Dirofilaria, with humans serving as accidental dead-end hosts. It most commonly affects middle-aged adults, presenting as pulmonary or subcutaneous nodules. Pediatric involvement is uncommon and may mimic benign or malignant lesions, leading to diagnostic challenges. We report the case of a 2-year-old female from a rubber plantation region who presented with a gradually progressive, painless submental swelling. Ultrasound revealed a hypoechoic lesion with mobile linear echogenic structures, suggestive of dirofilariasis. Surgical excision and subsequent histopathological examination confirmed the diagnosis of Dirofilaria infection. This case highlights an unusual pediatric presentation of dirofilariasis and emphasizes the importance of considering parasitic infestations in the differential diagnosis of head and neck swellings in endemic regions.
