METTA, Humberto et al. Endobronchial leiomyoma: an unusual non-defining neoplasm in a patient with AIDS. Rev. Inst. Med. trop. S. Paulo [online]. 2009, vol.51, n.1, pp. 53-55. ISSN 1678-9946. http://dx.doi.org/10.1590/S0036-46652009000100010.
Smooth muscle neoplasms are more frequent in human immunodeficiency infected children than in HIV seropositive adults. Endobronchial leiomyoma is a rare benign tumor in HIV infected adult patients. Epstein-Barr virus (EBV) has been implicated in the pathogenesis of these tumors. Here we describe an adult patient with HIV infection with atelectasis of the left upper pulmonary lobe as the first clinical expression of an intrabronchial leiomyoma. In this case, we can not show the association with EBV. Our report suggests that smooth muscle tumors as leiomyoma should be included in the differential diagnosis of endobronchial masses in AIDS patients.
