title: A case of Epstein-Barr virus-associated pulmonary leiomyosarcoma arising five yr after a pediatric renal transplant.
abstract: EBV-associated SMTs in immuno-compromised patients have recently been reported. We report on a case of EBV-associated pulmonary leiomyosarcoma arising five yr after renal transplantation. The patient was an eight-yr-old girl, who received a living related kidney transplant from her mother. She had had bilateral giant Wilm's tumors as an infant and underwent bilateral nephrectomy at one and two yr of age. At the age of seven, she suffered from bronchitis several times, and a year later, two nodules were detected in her left lung by X-ray and computed tomography. We suspected a recurrence of Wilm's tumor and performed surgical resection. The pathological finding was SMT with moderate mitosis and no evidence of Wilm's tumor. The fact that the tumors were positive for EBER suggested an association with the EBV. Six months later, there was a recurrence in her left lung. Surgical resection was performed, and immunosuppressive agents were reduced. Two yr after the second operation, she is well with no recurrence. We report the first case of EBV-associated pulmonary leiomyosarcoma in a pediatric patient after renal transplantation owing to a malignant tumor.
