Cardiothoracic Surgery: Other Lung Tumors

Isolated Lung Metastases

• Second Most Common Site of Metastasis
• Common Primary Sources:
  • Colorectal Cancer (Most Common)
  • Breast Cancer
  • Head & Neck Cancers
  • Prostate Cancer
  • Sarcoma
  • Bladder Cancer
• Treatment: Resection (If Not Otherwise Contraindicated)

Pulmonary Hamartoma

• Tumor of Fat, Cartilage & Connective Tissue
• The Most Common Benign Tumor
• CT Appearance: “Popcorn” Calcifications (Pathognomonic)
  • Only Seen in < 10% of Cases
• Treatment: Nothing

Pulmonary Mesothelioma

• Tumor of the Mesothelium
• Sites:
  • Pleura (Most Common)
  • Peritoneum
  • Pericardium
  • Tunica Vaginalis
• Malignant with Poor Prognosis
• Typically Related to Asbestos Exposure
  • *Primary Lung Cancer Still More Common than Mesothelioma After Asbestos Exposure
• Presentation: Chest Pain, Dyspnea, Cough, Hoarseness or Dysphagia
• Imaging Findings: Pleural Plaque, Diffuse Pleural Thickening or Pleural Effusion
• Treatment:
  • Resectable: Extrapleural Pneumonectomy with Chemotherapy and/or Radiation Therapy
  • Unresectable: Chemotherapy

Pulmonary Carcinoid Tumor

• *See Small Intestine: Carcinoid Tumor
• Primary Treatment: Surgical Resection

Other Lung Tumors

• Primary Pulmonary Sarcomas
• Primary Pulmonary Leiomyosarcoma
• Primary Pulmonary Angiosarcoma
