Spontaneous regression of an EBV-associated monoclonal large B cell proliferation in the mastoid of a young child following surgical biopsy.
We report the spontaneous regression of an Epstein-Barr virus-associated monoclonal lymphoid proliferation in an immunocompetent child. A 2-year-old male with acute otitis media presented with a right-sided facial palsy secondary to acute mastoiditis. During mastoid decompression a polypoid mass, a histologically diffuse large B cell lymphoma, was found. Staging revealed localized disease. At surgical re-exploration 5 weeks later the disease had resolved. Retrospective serological testing was consistent with an acute Epstein-Barr viral infection and in situ hybridization of the tumour tissue was positive for Epstein-Barr RNA.
