Primary pleural angiosarcoma associated with pneumoconiosis: An autopsy case

Area of Science:

• Oncology
• Pathology
• Pulmonology

Background:

• Pleural angiosarcoma is a rare malignant vascular tumor.
• Pneumoconiosis is a group of interstitial lung diseases caused by inhalation of dust particles.

Observation:

• A case of pleural angiosarcoma in an adult male was confirmed by autopsy.
• The patient presented with thickened pleura and nodular tumors in both lungs.
• Histological examination revealed epithelioid cells positive for CD31, CD34, vimentin, and cytokeratin, but negative for calretinin.

Findings:

• The autopsy also revealed pathological findings consistent with pneumoconiosis, including dystrophic ossification, anthracosis, and dust particles.
• These findings were present in the lung parenchyma and a hilar lymph node.

Implications:

• This case suggests a potential link between pneumoconiosis-associated pathologies and the development of pleural angiosarcoma.
• Further research is warranted to explore the etiological relationship between dust exposure and this rare malignancy.
