A nasal swelling revealing a metastatic testicular extranodal NK/T-cell lymphoma: A case report and a review of literature.

Testicular ENKTCL is a rare disease. Asia is the most affected. Primary testicular NK/T-cell lymphoma is rare. Metastases are early and the prognosis is poor. Metastases mainly involve the lymph nodes, skin, contralateral testis, bone marrow, spleen and central nervous system. Nasal metastasis giving rise to bifocal presentation is extremely rare. We report the management of a patient initially seen for a nasal swelling with a hidden history of scrotal swelling, in whom nasal biopsies as well as the analysis of the orchidectomy part made it possible to retain the diagnosis of ENKTCL of the testis with a nasal metastasis.
