Lymphoblastic lymphoma/leukaemia presenting as perichondritis of the pinna

Extra-nodal non-Hodgkin's lymphoma (NHL) of the pinna has only been reported once in a patient with immunodeficiency. We report an unusual case of lymphoblastic lymphoma in a patient without any immunodeficiency, presenting as an inflammatory lesion of the pinna, which illustrates the need to biopsy any non-healing lesion as soon as possible to ensure that such a treatable malignancy is diagnosed at an early stage.
