A case report of adult T-cell leukaemia/lymphoma (ATLL).

Adult T-cell leukaemia/lymphoma (ATLL) is a unique disease with distinct manifestations, a characteristic phenotype and a likely retroviral aetiology. It is unusual in Southeast Asia, though more commonly seen in some countries like Japan. We report a case of this disease in a 71-year-old man in Singapore who presented with papular erythematous eruptions for 6 years and subsequently developed generalised lymphadenopathy. He was diagnosed to have ATLL and, despite an initial response, became resistant to combination chemotherapy. We discuss the aetiology, characteristics and management of this interesting disease.
