Occurrence of Acute Myeloid Leukaemia in a Patient with Cutaneous Sarcoidosis

Abstract

There is a close relationship between sarcoidosis and malignancy, which is more pronounced in patients with cutaneous sarcoidosis. An intense T helper cell response occurs in sarcoidosis, with an imbalance between the activity of effector and regulatory T cells, which could be responsible for the coexistence of malignancy. We present a patient who developed acute myeloid leukaemia one and a half years after she was diagnosed with cutaneous sarcoidosis.
