Diagnosis With Brief Discussion

Diagnosis
Pulmonary Chondroid Harmatoma
Radiologic Findings
Pulmonary chondroid hamartoma, as a subtype of pulmonary harmatoma, is defined when chondroid tissue predominates in the composition of the tumor. Harmatoma is the most common benign tumor of the lung, which accounts for 8% of pulmonary neoplasms. Most patients with pulmonary hamartoma are asymptomic, whereas some patients may have respiratory symptoms such as hemoptysis, cough, or chest pain. Solitary pulmonary hamartoma is a common benign tumor that is usually seen in males, whereas multiple pulmonary hamartomas are rare and predominate in females. On radiology, a rounded shadow with well-defined margins and surrounded by normal looking lung parenchyma, with occasional foci of calcification. The typical 'popcorn' calcification which strongly suggests the harmatoma is present in about 10-30% of chest radiographs. CT scans are more sensitive for detecting calcification and adipose tissue but they may not be able to demonstrate the salient features each time and it may be difficult to distinguish benign from malignant lesions.
