Primary pulmonary angiosarcoma: Three case reports and literature review

Area of Science:

• Oncology
• Pathology
• Vascular Biology

Background:

• Primary pulmonary angiosarcoma is an exceptionally rare vascular malignancy.
• It is characterized by aggressive behavior and poor prognosis.
• Limited case reports exist in English literature, complicating diagnosis.

Observation:

• Three cases of primary pulmonary angiosarcoma are presented.
• Patients exhibited symptoms including cough, hemoptysis, and progressive dyspnea.
• These symptoms highlight the clinical presentation of this rare tumor.

Findings:

• The rarity of pulmonary angiosarcoma leads to a low index of clinical suspicion.
• Diagnosis is often delayed due to its infrequent occurrence.
• This report contributes valuable data to the scarce literature.

Implications:

• Increased awareness may improve early clinical suspicion and diagnosis.
• Further research into clinical characteristics, diagnosis, treatment, and prognosis is warranted.
• Understanding this rare tumor can potentially improve patient outcomes.
