Aggressive muscular non-Hodgkin lymphoma

Diagnosis of B‐cell lymphoma from gluteal muscle mass

“…Extranodal involvement of NHL is approximately 20%‐30% . Primary extranodal, located only on the extranodal site, commonly arise from gastrointestinal tract whereas, primary skeletal muscle non‐Hodgkin's lymphoma (PSM NHL) is rare, and constitutes up to 0.1 to 0.5% of NHL . Skeletal muscle is involved by lymphoma either in the course of disseminated disease, spread from contiguous lymph node or as a primary extranodal lesion.…”
