Pulmonary sarcomatoid carcinoma presenting as a lung abscess: A case report

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Pulmonary sarcomatoid carcinoma (PSC) is an uncommon non-small cell lung cancer variant.
• Distinguishing PSC from benign conditions like lung abscess can be diagnostically challenging.

Observation:

• A 69-year-old male presented with fatigue and anorexia.
• Chest CT revealed a right lower lobe mass with unusual imaging characteristics.
• Initial treatment for suspected lung abscess with antibiotics proved ineffective.

Findings:

• Histopathological examination post-lobectomy confirmed sarcomatoid carcinoma.
• The tumor exhibited smooth margins and lacked internal contrast enhancement on CT.
• The case underscores the difficulty in differentiating PSC from lung abscess based on initial presentation.

Implications:

• This case highlights the importance of considering rare malignancies in the differential diagnosis of lung masses.
• Accurate histopathological diagnosis is crucial for appropriate treatment and patient management.
• Further research into early diagnostic markers for PSC may improve patient outcomes.
