Epstein-Barr Virus-Associated Smooth Muscle Tumor of the Bronchus After Peripheral Blood Stem Cell Transplantation.

Epstein-Barr virus (EBV)-associated smooth muscle tumors (SMTs) are rare mesenchymal neoplasms that typically develop in patients with congenital or acquired immunodeficiency and after solid organ transplantation. However, their occurrence after hematopoietic stem cell transplantation has rarely been reported. Furthermore, EBV-SMTs appear as multifocal tumors that can be manifested in a range of anatomic locations. Here, we present a case of successful excision of an EBV-SMT in the proximal bronchus by complex segmentectomy after partial hepatectomy for a liver lesion. Given the recurrence risk of EBV-SMTs, segmentectomy was identified as a successful surgical procedure for preserving pulmonary function.
