Adult pulmonary blastoma.

Area of Science:

• Oncology
• Thoracic Surgery
• Pulmonology
• Pathology

Background:

• Pulmonary blastoma is a rare, aggressive primary lung tumor with challenging diagnosis due to vague symptoms.
• Chronic smokers are at increased risk for various lung pathologies, including rare malignancies.

Purpose of the Study:

• To present a case of biphasic pulmonary blastoma in a middle-aged male smoker.
• To emphasize the diagnostic challenges and the importance of integrated diagnostic approaches.
• To highlight the role of histopathology and immunohistochemistry (IHC) in confirming the diagnosis and guiding treatment.

Main Methods:

• Clinical presentation of a chronic smoker with cough and hemoptysis.
• Radiological assessment including Computed Tomography (CT) scan revealing a left upper lobe mass.
• Diagnostic challenges with CT-guided biopsy, leading to surgical resection for definitive diagnosis.
• Histopathological examination and immunohistochemistry (IHC) for confirmation.
• Initiation of adjuvant chemotherapy postoperatively.

Main Results:

• Surgical resection was essential for diagnosing biphasic pulmonary blastoma after inconclusive biopsy.
• Histopathology and IHC confirmed the rare tumor type.
• Adjuvant chemotherapy was administered post-surgery.

Conclusions:

• This case underscores the diagnostic difficulties associated with pulmonary blastoma.
• Accurate diagnosis relies on comprehensive evaluation including histopathology and IHC.
• Further research is needed to define optimal management strategies for pulmonary blastoma.
