Biopsies of suspected lymphoma cases with history of pre-biopsy corticosteroid therapy present several diagnostic issues, such as the inability to demonstrate the neoplastic hematolymphoid cells, the similarity of post-corticosteroid changes with inflammatory demyelinating lesions, and the possibility of a demyelinating lesion preceding a central nervous system lymphoma. This report presents the case of a 51-year-old immunocompetent male with a solitary callosal mass, with immunomorphologic features suggestive of a demyelinating lesion on initial biopsy, and upon re-biopsy after three months revealed a diffuse large B-cell lymphoma. Awareness of these issues in post-corticosteroid stereotactic biopsy specimens, together with adequate clinical and radiologic data, is important for proper diagnosis and further therapeutic guidance.
