Chronic Eosinophilic Pneumonia: Unraveling Recurrent Chest Infections in a Female Patient With a Family History of Atopy.

Eosinophilic pneumonia is a rare condition characterized by the infiltration of eosinophils in the lungs. We present a case of eosinophilic pneumonia in a 51-year-old British Caucasian female with a history of lichen sclerosus, deranged liver function tests, and a family history of atopy. The patient presented with fever, shortness of breath, lethargy, dry cough, and weight loss over a three-month period. Initial treatment with antibiotics did not yield improvement, and further investigations revealed marked eosinophilia on blood count. Bronchoscopy and biopsies confirmed the diagnosis of eosinophilic pneumonia, and the patient responded well to a tapering dose of prednisolone. This study highlights the importance of considering eosinophilic pneumonia in patients with unexplained respiratory symptoms and eosinophilia and emphasizes the role of bronchoscopy in establishing a definitive diagnosis.
