CLINICO-RADIOLOGIC FINDINGS IN PRIMARY CUTANEOUS EXTRANODAL NATURAL KILLER/T-CELL LYMPHOMA, NASAL TYPE MIMICKING CELLULITIS OF THE LEFT ARM (CASE REPORT)

摘要

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/Tcell 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.
