ABSTRACT
Abstract Nasal type extranodal NK/T-cell lymphoma is a distinct entity according to the World Health Organization classification. Although 60% to 90% of patients with this disease present with a destructive mass in the midline facial tissues, it may also primarily or secondarily involve extranasal sites, like the skin. We report the case of a 77-year-old patient that came to our department with erythematous plaques of the right leg and eczematous lesions of the trunk. These lesions were biopsied and the patient was diagnosed with extranodal NK/T-cell lymphoma, nasal type. He was treated with multi-agent systemic chemotherapy but died 5 months after diagnosis. This case highlights the rarity and variability of cutaneous features of this disease and its aggressive course and poor prognosis.
