Background Lymphatic filariasis leading to the passage of white urine or chyle is a rare manifestation in children. Filarial parasite infiltration leading to abnormal lymphatic–urinary communication occurs with prolonged infection. The incubation period ranges from 5 to 20 yrs., thus relatively infrequent in the pediatric age group. Index of suspicion should be high when a child presents with the passage of white urine because the subclinical manifestation of filarial infection is difficult to recognize. Moreover, more pathognomonic clinical manifestations such as lymphoedema or hydrocoele are present in adulthood. It should also be differentiated from non-parasitic causes like nephrotic syndrome, urates and phosphates in urine, and congenital lymphatic-urinary communication. Case Presentation We report two pediatric cases with the intermittent passage of milky white urine since one year. Institutional ethical committee approved the study. In both patients, urine triglycerides were high, and the presence of positive filarial antigen test confirmed the diagnosis. Medical management showed remission of symptoms. Our cases highlight the rare presentation of LF in children and the use of point of care diagnostic tests, management, and outcome in them. Conclusion LF is a rare condition in children, and the index of suspicion should be high for early management.
