Abstract.
A 3-month-old female child suffered from tachypnea and dyspnea with abnormal blood gas values. Chest X-rays revealed an increased transparency of the left lung and a mediastinal shift to the right side. High resolution computed tomography (CT) documented a narrowing of the left upper stem bronchus. Ensuing endoscopy detected an occlusive endobronchial tumor mass that did not infiltrate the bronchial cartilage as confirmed with endobronchial ultrasonic monitoring. Based on gross histological examination of the surgical specimen obtained using sleeve resection, the highly vascularized tumor exhibited an adenomatoid growth pattern with a rather homogeneous population of nuclei. The light microscopical presentation was consistent with a juvenile (infantile) hemangioma, which was confirmed using immunohistochemical examinations despite the display of neuroendocrine features. Although endobronchial juvenile hemangiomas are an extremely rare event in early childhood, this case underscores the necessity to not neglect its occurrence in differential diagnosis.
