Area of Science:

  • Pulmonology
  • Oncology
  • Pathology

Background:

  • Pulmonary hamartomas are rare lung neoplasms of dysontogenetic origin, typically presenting in adults with cartilaginous tissue.
  • They are often asymptomatic and discovered incidentally on chest radiographs.

Observation:

  • A rare case of a 25-year-old student with a large (7 cm) pulmonary hamartoma is presented.
  • The hamartoma exhibited a predominantly vascular histological nature, mimicking angiosarcoma macroscopically, with peripheral calcifications noted on CT scan.
  • The patient's young age at onset (around 10 years) and the tumor's significant size are exceptional features.

Findings:

  • The histological examination revealed a primarily vascular hamartoma, distinct from the usual cartilaginous type.
  • Imaging studies, including CT scan, identified peripheral calcifications within the lesion.

  • The tumor size exceeded typical reported parameters for pulmonary hamartomas.

    • Implications:

    • This case expands the understanding of the diverse histological presentations and potential size variations of pulmonary hamartomas.
    • The findings suggest that vascular hamartomas, despite their rarity, should be considered in the differential diagnosis of lung neoplasms, especially in younger individuals.
    • Further research into the growth rate and doubling time of such exceptional cases is warranted to improve diagnostic and therapeutic strategies.
