We describe a 74-year-old woman with the diagnosis of natural killer (NK)-cell leukaemia and autoimmune pathology. Four years previously, a diffuse large B cell non-Hodgkin's lymphoma had been diagnosed and treated effectively. Although NK-cell leukaemia has been thought to be a distinct highly aggressive clinicopathological entity, our case shows no further evolution at the present time. As far as we know, this association has not been previously described in the literature.

Lymphomas are classified as either Hodgkin's or non-Hodgkin's. The 2 subtypes of non-Hodgkin's lymphoma that can present primarily in the skin are cutaneous T-cell lymphoma and cutaneous B-cell lymphoma, both of which tend to be low-grade malignant neoplasms. Recently another distinct subtype of lymphoma was discovered, the natural killer (NK)/T-cell lymphoma, which can involve the skin in a primary or secondary fashion. The NK/T-cell subtype of lymphoma is characterized by the expression of the NK-cell antigen CD56. These CD56(+) lymphomas are further subdivided into nasal NK/T-cell lymphomas that commonly present as midfacial destructive disease and non-nasal NK/T-cell lymphomas that often arise in extranodal locations, including the skin. We report a case of aggressive NK-cell leukemia/lymphoma with numerous secondary cutaneous lesions and review the clinical and histopathologic spectrum of non-nasal CD56(+) lymphomas, with an emphasis on the dermatologic findings.

To analyze the clinicopathologic characteristics of childhood non-Hodgkin's lymphoma (NHL) associated with Epstein-Barr virus (EBV), EBER in situ hybridization was performed in 80 cases of NHLs. EBER-positive lymphomas account for 25% (20/80) and include NK/T-cell lymphoma (6/6), aggressive NK-cell leukemia (1/1), peripheral T cell lymphoma (5/11), diffuse large B-cell lymphoma (5/14), hydroa-like T-cell lymphoma (1/1), marginal zone B-cell lymphoma (1/2), and post-transplantation lymphoproliferative disorder (1/1). Other types including 19 cases of Burkitt's lymphoma were negative. For 9 EBER-positive cases, immunohistochemical staining for LMP-1, and EBNA-2 was performed to determine the EBV latency pattern. Two of nine EBER-positive cases expressed both LMP-1 and EBNA-2. Clinically, patients with EBV-positive B-cell lymphomas were cured with chemotherapy, whereas EBV-associated NK- and T cell lymphomas pursued fatal clinical course. In conclusion, EBVs infected in childhood NHLs are frequently associated not only with NK- and T- cell lymphomas but also large B-cell lymphomas.
