Clinico-Radiologic Findings in Primary Cutaneous Extranodal Natural Killer/T-Cell Lymphoma, Nasal Type Mimicking Cellulitis of the Left Arm

Extranodal natural killer (nk)/t-cell lymphoma is a very rare and aggressive disease characterized histopathologically by an epstein-barr virus (ebv)-positive atypical lymphoid cytotoxic infiltrate, extensive vascular destruction, and prominent tissue necrosis. it commonly shows cutaneous lesions that primarily or secondarily mimic cellulitis at the primary site. we report on a very rare case of extranodal nk/t-cell lymphoma, nasal type of skin/soft tissue, in a 64-year-old man, and describe the radiological findings. the condition was misdiagnosed as cellulitis of the left arm based on initial noninvasive clinical and radiologic work-up.
