The authors describe five white patients with peripheral T‐cell lymphoma. Four patients were older than 65 years. All cases presented with a short clinical course and advanced stage at the time of diagnosis. Clinical manifestations included asthenia, weight loss, peripheral and abdominal lymphadenopathy. One case showed tonsillar involvement and subcutaneous lymph node enlargement; hepatomegaly was present in four cases, two of them with splenomegaly. Only one case presented peripheral lymphocitosis and antibodies to human T‐leukemia virus. Although three cases were classified as diffuse mixed lymphomas and two as poorly differentiated lymphocytic lymphomas, there were some common characteristics: diffuse infiltration by different proportions of small lymphoid cells and large immunoblasts, some of them multinucleated and similar to Reed‐Sternberg cells; accumulation of histiocytes, plasmacytosis, eosinophilia, venular proliferation and compartmentalization were also found. Bone marrow infiltration was observed in two patients. Results of monoclonal markers showed four cases to be OKT4+ and the other OKT8+. The morphologic and immunologic characteristics of these patients were typical and similar to those reported from other geographical areas.
