Abstract

Extranodal nasal-type natural killer/T-cell lymphoma may arise anywhere outside the lymph nodes, predominantly including the nasal cavity, nasopharynx, oropharynx, upper respiratory tract, gastrointestinal tract, skin, testes, and salivary glands, whereas primary tumor arising in muscle is rarely documented. We report FDG PET/CT findings of primary extranodal nasal-type natural killer/T-cell lymphoma in the muscles of the right lower limb in an 82-year-old man.
