title: [Extranodal NK/T cell lymphoma of the nasal type].
abstract: The vast majority of lymphoma occurring in the testis are diffuse large B-cell Lymphoma. We report on a case of natural killer/T cell lymphoma in a forty four year old male, with bilateral testicular and cutaneous involvement with a highly aggressive course. The tumor cells were positive for both CD56 and Epstein Barr Virus, encoded EBER molecules, and showed focal angiocentric growth thus fullfilling the criteria for NK/T cell lymphoma of nasal type. Dermatopathologists and uropathologists should be aware of this rare entity which may only be diagnosed after extensive inmunohistochemical studies.
