High-grade Burkitt Lymphoma Presenting as a Buttock Mass and Foot Drop

Abstract

Burkitt lymphoma (BL), a highly aggressive B-cell non-Hodgkin lymphoma (NHL), usually presents in children and young adults with large extranodal masses involving jaw bones, gastrointestinal tract, and central nervous system. The three main subtypes of BL are endemic, sporadic, and immunodeficiency variant. Extranodal involvement is common in each variant of BL, although muscle tissue involvement is distinctly rare. Mode of spread may be hematogenous or via direct extension of the primary tumor. In this report, we present a case of a 41-year-old male who presented with a palpable mass in the buttock leading to foot drop as the initial manifestation of BL. An exhaustive review of the literature failed to discover any previous reports of BL occurring in this location.
