Sparganosis in a patient with diffuse large B cell lymphoma.

Sparganosis is the human infection by plerocercoid, the larvae of sparganum. Clinically, subjective symptoms do not occur in the incipient stage, but as the worm migrates, pruritus or tenderness may occur. On physical examination, soft, palpable, and sometimes migratory, subcutaneous nodules are found in sparganosis patients. As rare cases; sparganosis from the orbit, the abdominal viscera, and the breast have been reported. However, there have been no reports relating such disease to the patients' immunocompromised status.We experienced a case of sparganosis from a patient with lymphoma whose immune system was suppressed by anticancer therapy, suggesting that the immunosuppression might affect the onset and the exacerbation of the disease. We report our case with a review of the literature.
