Abstract

Cutaneous T-cell lymphomas (CTCL) are diseases characterized by cutaneous infiltrates of malignant clonally expanded T cells. CTCL cells exhibit a cytokine profile consistent with T helper-2 type (TH2) cells. Eosinophilic pneumonias are individual syndromes characterized by eosinophilic pulmonary infiltrates and commonly peripheral blood eosinophilia. CTCL and chronic eosinophilic pneumonia are rare clinical entities. We report a patient with the association of CTCL and chronic eosinophilic pneumonia. To understand the mechanism leading to the eosinophilia, we examined the patient's cytokine profile. This was consistent with a high TH2 activity. Her interleukin (IL) 5, 6, and 10 levels were extremely high, while her IL-2 and interferon-γ (IFN-γ) levels (TH1 profile) were low. We believe that eosinophilic pneumonia in this patient is probably secondary to high TH2 cytokine levels induced by tumor cells. We suggest that eosinophilic pneumonia should be considered as a possible diagnosis in patients with CTCL who have respiratory complaints.
