Abstract
Background: Pulmonary epithelioid hemangioendothelioma is a rare malignant disease, and most cases are found as multiple lung nodules, rarely as a single nodule.
Case: Computed tomography( CT) in a 71-year-old man revealed a growing 3-mm lung nodule in the left S6 after rectal cancer operation. Wedge resection was performed. A pathological examination resulted in a diagnosis of pulmonary epithelioid hemangioendothelioma based on CD31 and CD34 positivity in immunohistochemistry.
Conclusion: When new nodules are noted on routine CT scans of other malignancies, it is essencial to make a pathological diagnosis, bearing in mind that pulmonary nodules can arise from a variety of causes.
