Pulmonary artery sarcoma masquerading as pulmonary embolism: an under-recognised entity

Area of Science:

• Oncology
• Cardiovascular Surgery

Background:

• Pulmonary artery sarcoma is a rare malignancy with limited reported cases.
• It presents with diverse histological subtypes including leiomyosarcoma and spindle cell sarcoma.

Observation:

• The disease is frequently misdiagnosed as pulmonary thromboembolism, leading to delayed diagnosis and treatment.
• This diagnostic delay contributes to significant mortality, exacerbating an already poor prognosis.

Findings:

• Complete surgical resection is the primary treatment modality for pulmonary artery sarcoma.
• Adjuvant therapies like chemotherapy and radiation have shown variable efficacy.

Implications:

• Early and accurate diagnosis is crucial for improving patient outcomes.
• Aggressive surgical management followed by regular surveillance is indicated due to the tumor's aggressive nature.
