Adult biphasic pulmonary blastoma

Area of Science:

• Oncology
• Thoracic Surgery
• Pathology

Background:

• Pulmonary blastoma is a rare malignant lung tumor resembling fetal lung tissue.
• Fewer than 200 cases reported globally since 1945.
• Predominantly affects children but occurs in adults, peaking in the fourth decade.

Observation:

• A 51-year-old adult patient presented with a large biphasic pulmonary blastoma.
• The tumor's histological appearance did not predict its variable clinical course.
• Surgical excision was performed as the treatment modality.

Findings:

• The patient remained disease-free 11 months after surgical treatment.
• Biphasic (type 2) tumors are associated with high relapse rates.
• Close monitoring is crucial for patients with large biphasic pulmonary blastoma.

Implications:

• Pulmonary blastoma, though rare in adults over 20, must be considered in adult lung mass differential diagnoses.
• This case demonstrates the potential for successful surgical management in adult pulmonary blastoma.
• Long-term surveillance is essential for patients with large biphasic pulmonary blastoma to detect potential recurrence.
