Filariasis, a neglected tropical disease, is a global health problem and is endemic to 73 countries including India. It is caused by nema- todes of Filariodidea family, namely, W. bancrofi and B. malayi in India, which have a predilection for the lower limbs and testis. We report a never before reported case of flariasis of the main parotid duct in a 25-year-old male that resolved on medical management, exemplifying the importance of maintaining a high index of suspicion and careful examination of cytological smears in endemic countries, allowing for an early diagnosis and treatment, decreasing the morbidity of this debilitating disease. 1. Introduction Filariasis, a neglected tropical disease, is a global health prob- lem afecting 73 countries, including India, with a population of over 1.2 billion at risk for infection [1]. It is caused by infection with nematodes of the family Filariodidea, namely, Wuchereria bancrofi (90% cases), Brugia malayi (majority of remainder cases), and B. timori (rare), of which the former two are found in India. Although these parasites have a marked predilection for lower limb lymphatics, the epididymis, and the spermatic cord [2], they have also been reported to occur at unusual sites such as the thyroid gland [3], body fuids [4], skin [5], breast [6], and the oral or perioral region [7]. Salivary gland involvement is very rare and has been reported only once previously [8]. Here, we report a previously unreported case of flariasis of the parotid duct in a young adult male. 2. Case Report A 25-year-old man, resident of Uttar Pradesh, presented to the otorhinolaryngology outpatient department with a painless swelling of the lef cheek, gradually increasing in size since he frst noticed it 1 year earlier. He gave a history of temporary increase in size of the swelling while eating, with subsequent return to previous size on completion of a meal. On examination, a 2 cm × 1.5 cm globular swelling was present just below the lef malar prominence, which, on palpation, was nontender, euthermic, frm, and mobile in all directions with no fxity to skin or underlying tissues and a grossly normal overlying skin. Te swelling increased in prominence when the patient was made to clench his teeth. He was afebrile, with no lymphadenopathy or organomegaly. His complete blood counts revealed absolute eosinophilia (1100/mm 3 ), with an essentially normal peripheral smear. On ultrasonography, a cystic dilatation of the middle part of the lef Stensen’s duct was seen with minimal lobulated sof tissue contents and a mildly thickened duct wall. A contrast enhanced computed tomography scan was done that showed a small, well defned, hypodense cystic lesion superfcial to the anterolateral aspect of the lef masseter muscle indenting its surface, communicating with a tubular hypodense struc- ture communicating with the parotid gland, suggestive of a dilated Stensen’s duct with a sialocele formation (Figures 1(a) and 1(b)). Afer clinical and radiological examination, the diferen- tial diagnosis that came to our mind was that it is either a sialolith blocking the duct that has lead to the infammatory swelling or cysticercosis but further investigations showed a diagnosis which was very diferent and rare.
