Pediatric trichinosis: A case report.

Background: Trichinellosis is a zoonosis, caused by roundworms of the genus Trichinella. Domestic pigs, wild boars, bears, rodents and horses are reservoir animals. We report a case of neck trichinosis presenting as lateral neck swelling. The diagnosis of trichinosis was confirmed by the presence of larvae on muscle biopsy. Furthermore, lateral neck swelling may provide a diagnostic challenge by clinically mimicking a lymphoma or other causes of lateral neck swelling. Due to its rarity and its tendency to pose a clinical diagnostic challenge, we decided to report it.

Case Presentation: A-10 yr old male patient presented with a 6 × 4 cm firm; non-tender left lateral neck swelling. Histopathology examination confirmed the diagnosis of trichinosis and the patient was started on albendazole 15 mg/kg/day, divided into two doses and prednisolone 20 mg by mouth, two times daily, for 14 days. Having completed his medication, he had a smooth course and was discharged with appointment scheduled for follow-up after 3 months.

Discussion: Trichinella spp. occur worldwide, most frequently in regions with temperate climates. About 10,000 human infections occur annually worldwide. Cultural factors such as traditional dishes based on raw or undercooked meat or meat-derived products play an important role in the epidemiology of the disease.

Conclusion: In the clinical evaluation of a patient with lateral neck swelling, trichinosis must be considered as a differential diagnosis in subjects from endemic areas for early diagnostic workup and management.
