Pneumonic-Type Non-Mucinous Adenocarcinoma of Lung Presenting With Progressive Respiratory Failure - A Case Report

Introduction: Non-mucinous lepidic adenocarcinoma with pneumonic presentation is a rare form of lung cancer. Its ability to mimic infectious and inammatory diseases in both patient presentation and diagnostic imaging can result in a delayed diagnosis.1 A 58-year-old non-smoker female, known case of T2DM presented with complaints of Case Report: persistent cough with bronchorrhea (1000ml/ day) for 8 months and progressive dyspnea (MMRC-4), fatigue, loss of appetite with weight loss of 5kg in the last 2 months. Multiple hospitalizations in the past for similar complaints and was treated empirically as respiratory tract infection. The distinctive feature of this patient's presentation was that the classic imaging features like presence of nodular masses, usually seen in malignancy and bronchoscopy ndings of airway lesions or other abnormalities were not seen. Diagnosis of lepidic adenocarcinoma was possible after transbronchial biopsy (TBLB). It is prudent to have high index of suspicion in patients presenting Conclusion: with bronchorrhea with persistent alveolar opacity due to its ability to mimic both infectious and inammatory diseases
