Sweet's syndrome associated with cutaneous T cell lymphoma.

Although the association of Sweet's syndrome with haemoproliferative disorders or solid malignant tumors is well known, only two previous observations associated with T lymphoma have been reported. We report the first observation of Sweet's syndrome associated with cutaneous T cell lymphoma. The role of a cytokine cascade released by an abnormal T cell clone is discussed as an initiating event responsible for secondary infiltration with neutrophils.
