Carcinoid Tumor Presenting as Hemoptysis and Elevated Diaphragm

Area of Science:

• Pulmonology
• Oncology
• Radiology

Background:

• Bronchial carcinoid tumors are rare pulmonary neuroendocrine neoplasms.
• Patients may present with nonspecific respiratory symptoms.

Observation:

• A patient presented with recurrent hemoptysis and dyspnea on exertion.
• Initial chest X-ray revealed an elevated right hemidiaphragm and atelectasis.
• Computed tomography (CT) identified a large tumor obstructing the right main stem bronchus.

Findings:

• Bronchoscopy with biopsy confirmed a pulmonary carcinoid tumor diagnosis.
• The tumor occluded 90% of the bronchial lumen.
• Surgical resection (right upper lobe sleeve lobectomy) and lymph node dissection achieved complete tumor eradication.

Implications:

• This case underscores the necessity of a broad differential diagnosis for hemoptysis and elevated diaphragm.
• Early and accurate diagnosis of pulmonary neuroendocrine tumors is crucial for effective management.
• Multidisciplinary approaches involving pulmonology, oncology, and radiology are vital for rare lung tumors.
