Introduction: Anaplastic Large T cells Lymphoma is a rare pathology, determined by expression of CD30 and differences in presentation and aggressiveness according to the ALK expression. Objectives: This study seeks to determine the epidemiological, clinicopathological and prognosis of patients with Anaplastic Large T-cell Lymphoma.
