Thrombocytosis in Chronic Eosinophilic Pneumonia

Thrombocytosis has not yet been described in chronic eosinophilic pneumonia. A typical patient with chronic eosinophilic pneumonia is described. The patient's thrombocyte count was up to 900,000 per cu mm, which returned to normal under steroid therapy. Thrombocytosis may be associated with chronic inflammation and should not require further investigations such as lung biopsy, in an otherwise usual case of chronic eosinophilic pneumonia.
