  • • Uncommon

    • < 1% of pulmonary tumors

    • Include:

    • -Fibromas

      -Leiomyomas

      -Neurofibromas

      -Myoblastomas

      -Benign metastasizing leiomyomas

    • Most lesions peripheral

++

Symptoms and Signs

+

  • • Peripheral: Asymptomatic

    • Central lesions: Cough, wheezing, hemoptysis, recurrent pneumonia

++

Imaging Findings

+

  • Chest film: 1-2 cm well-circumscribed, bosselated lower lung nodule with calcifications in 10-30%

+

  • • May be difficult to distinguish from malignant lesions; distinction may occur only after excision

+

  • • Chest x-ray

    • Bronchoscopy may be needed for central lesions

    • Pathologic diagnosis obtained by surgery or fine-needle aspiration

+

  • • Wedge resection

    • Lobectomy if involves proximal airway and associated with infections or bronchiectasis

++

Surgery

++

Indications

+

  • • Tissue diagnosis, if unobtainable by bronchoscopy

++

Prognosis

+

  • • Excellent
