Vulvar Mass

Smooth muscle tumors in immunocompromised patients have a strong association with Epstein-Barr virus (EBV) infection. EBV-associated smooth muscle tumors (EBV-SMT) are considered as a distinct group of smooth muscle tumors with different clinicopathologic features from conventional smooth muscle tumors. A 31-year-old female patient presented with a 2-cm mass at the left labium majus, the clinical diagnosis of which was a Bartholin lesion. She had acquired immunodeficiency syndrome diagnosed 29 months before. Excisional biopsy revealed a cellular tumor composed of round- to spindle-shaped cells with mild to moderate nuclear atypia. The tumor cells were immunoreactive for smooth muscle actin and muscle actin (HHF-35). Evidence of EBV infection was confirmed by in situ hybridization for EBV-encoded small RNA-1. To our knowledge, this is the first case of EBV-SMT presenting as a vulvar mass. EBV-SMT should be included in the differential diagnoses of mesenchymal tumor in patients with immunosuppression and in the differential diagnoses of smooth muscle tumor in uncommon sites, including the vulva.

Abstract Epstein-Barr virus infection has been linked to the development of smooth muscle tumors in immunocompromised patients with organ transplants and acquired immunodeficiency syndrome. A 52-year-old female recipient of a renal transplant presented with enlarging masses of the left iris. Incisional biopsy of the mass revealed a smooth muscle tumor of the iris. Epstein-Barr virus infection was confirmed by in situ hybridization for Epstein-Barr virus–encoded, small RNA in tumor cells. Eight months after total iridectomy the patient was free of disease. Although the prognosis and classification of Epstein-Barr virus–associated smooth muscle tumors are controversial, mortalities caused by these tumors are rare.

Abstract The Epstein-Barr virus (EBV) is associated with distinct forms of human lymphoid malignancies, including the endemic (eBL) and sporadic forms of Burkitt's lymphoma (sBL) and acquired immunodeficiency syndrome- associated non-Hodgkin lymphoma (AIDS-NHL). However, whether EBV has a pathogenetic role in these tumors or is a passenger virus has not been conclusively demonstrated. One element to distinguish between these two possibilities is to determine whether EBV infection has preceded and, thus, possibly contributed to clonal expansion, or whether infection has occurred after clonal expansion and thus is unlikely to contribute to pathogenesis. Toward this end we analyzed the structure of the heterogeneous genomic termini of EBV as markers of clonal infection in a panel of eBL (11 cases), sBL (9 cases), and AIDS-NHL (10 cases) biopsies. We show that EBV termini are uniformly clonal in sBL, eBL, and AIDS-NHL, strongly suggesting that EBV infection has preceded and, thus, most likely contributed to clonal expansion in these malignancies.

We describe the clinicopathologic features of an Epstein-Barr virus (EBV)-associated smooth muscle tumor arising in the basal ganglia of a 10-year-old human immunodeficiency virus (HIV)-positive child. Only a few cases of intracranial smooth muscle tumors are reported in the literature and virtually all of these have been extra-axial, involving the dura or sinuses in HIV+ adults. Our case underscores the need to include an EBV-associated smooth muscle tumor in the differential diagnosis when evaluating intracranial mass lesions in immunodeficient children.

EBV was found in all smooth muscle tumors from the six HIV-infected cases, but not in smooth muscle tumors from HIV-negative controls. All tumors studied stained for CD21 (EBV receptor), but levels were higher on tumor cells from HIV-infected cases than controls. This suggests that perturbation of the immune system (as in AIDS) may increase the production of the EBV receptor and/or that EBV infection itself causes increased receptor expression. It is postulated that EBV may contribute to smooth muscle tumorigenesis in HIV infection and potentially in other immunosuppressed states.
