Mediastinal hemangiomas
Abstract:
Hemangiomas of the mediastinum are rare tumors. Fewer than 100 have been reported. This study reviews the cases of 15 patients with mediastinal hemangiomas confirmed pathologically. We analyzed and evaluated the presentation, evaluation, and treatment. Follow-up is available for 14 of the 15 patients and ranges from 15 months to 15 years. Eight of the 15 patients were seen with signs and symptoms related to the tumor. This presentation correlated with invasion of contiguous mediastinal structures by the tumor. Six patients underwent total excision and 6, subtotal excision. During follow-up, residual tumor did not spread, become symptomatic, or show evidence of malignant degeneration. Based on this analysis, we believe that in patients in whom total excision of this tumor can be accomplished only by hazardous resection, a subtotal resection should be performed.
Insights
Mediastinal hemangiomas are rare. Subtotal resection is recommended when total excision of these benign tumors poses significant risks, as residual tumors showed no adverse progression.
Area of Science:
- Thoracic Surgery
- Surgical Oncology
- Pathology
Background:
- Mediastinal hemangiomas are uncommon benign vascular tumors.
- Fewer than 100 cases have been documented in medical literature.
- These tumors can cause symptoms due to invasion of adjacent structures.
Purpose of the Study:
- To review and analyze the clinical presentation, diagnostic methods, and treatment outcomes of mediastinal hemangiomas.
- To evaluate the long-term follow-up of patients treated for mediastinal hemangiomas.
- To establish recommendations for surgical management based on observed outcomes.
Main Methods:
- Retrospective analysis of 15 pathologically confirmed cases of mediastinal hemangioma.
- Review of patient records for presentation, diagnostic imaging, surgical procedures, and follow-up data.
- Correlation of presenting symptoms with tumor characteristics and invasion.
Main Results:
- Eight of 15 patients presented with symptoms, often related to tumor invasion.
- Six patients underwent complete tumor excision, and six had subtotal excision.
- Follow-up for 14 patients (15 months to 15 years) showed no tumor spread, recurrence, or malignant transformation in residual masses.
Conclusions:
- Subtotal resection is a viable and safe option for mediastinal hemangiomas when complete excision is technically challenging or hazardous.
- Benign mediastinal hemangiomas, even when incompletely resected, demonstrate a low risk of progression or malignant change.
- Careful patient selection and surgical strategy are crucial for optimal outcomes in managing these rare tumors.
