  • Title: Cutaneous Epstein-Barr virus-associated smooth muscle tumor in immunosuppression.
    Author: Matin RN, Ieremia E.
    Journal: J Cutan Pathol; 2021 Feb; 48(2):325-329. PubMed ID: 33245561.
    Abstract:
    A 36-year-old renal transplant recipient presented 15 months post-transplantation with a cutaneous spindle cell neoplasm with features of smooth muscle differentiation treated with local excision. 1.4 years later, a magnetic resonance imaging liver scan with gadolinium demonstrated multiple bilobar enhancing hepatic lesions, in keeping with metastases. A core biopsy revealed morphological appearances similar to the previous cutaneous spindle cell neoplasm. Epstein-Barr virus early RNA (EBER) in situ hybridization demonstrated strong diffuse staining of both cutaneous and liver tumor cells for EBER indicative of Epstein-Barr virus (EBV) infection. This is a rare presentation of multifocal EBV-associated smooth muscle tumors first presenting in the skin in an adult renal transplant recipient, which, despite being multifocal and involving the liver, may confer a better prognosis than predicted.
