Summary
This study reports the first case of a hemangioma in a pulmonary hilar lymph node. This rare vascular tumor requires differentiation from malignant vascular neoplasms.
Area of Science:
- Pathology
- Vascular Biology
- Pulmonology
Background:
- Lymph node vascular proliferations are uncommon.
- Hemangiomas within lymph nodes are exceptionally rare.
Observation:
- A 73-year-old male presented with a lung nodule diagnosed as squamous cell carcinoma.
- Post-lobectomy, a pulmonary hilar lymph node revealed a distinct hemangioma characterized by capillary proliferation.
Findings:
- Histopathological and immunohistochemical analysis (Factor VIII, CD34 positive) confirmed a primary lymph node hemangioma.
- The resected squamous cell carcinoma showed no lymph node metastasis.
Implications:
- This case highlights the importance of distinguishing intranodal hemangiomas from malignant vascular tumors.
- Accurate diagnosis is crucial for appropriate patient management and prognosis.
