This is a case description of a female patient, 77 years-old, who presented with progressive dyspnea and cough. She had a mild hypoxemia in the arterial blood gases (PaO2 72 mmHg) and normal spirometry. The chest computer tomography revealed diffuse “ground glass” opacities, segmental alveolitis, bronchiectasis, fibrotic lesions and numerous micronodules. A thoracoscopy was performed and the obtained biopsy showed carcinoid tumorlets, with positive CK8/18, CD56, TTF-1 and synaptophysin immunohistochemical markers. Pulmonary carcinoid tumorlets are rare, benign lesions and individuals with tumorlets are typically asymptomatic. Our report presents a symptomatic clinical case of carcinoid tumorlet.
