Epithelial granuloma occurring on the staple‐stump after segmentectomy for ovarian cancer lung metastasis
When a mass occurs at the staple line following lung resection, it can be difficult to distinguish between local cancer recurrence and granuloma. We present a case of a staple‐line granuloma with 18F‐fluorodeoxyglucose‐positron emission tomography uptake and elevated serum carbohydrate antigen 19–9 (CA19‐9) in a patient with ovarian cancer lung metastasis. After granuloma resection, serum CA19‐9 levels normalized, and CA19‐9 positive cells were identified in the resected tumor. Therefore, serum CA19‐9 elevation does not rule out a staple‐line granuloma. Whereas granulomas on computed tomography (CT) scans tend to show smooth shadows along the staple line unilaterally, detailed CT evaluation may help diagnostic differentiation. Differentiation based on imaging and tumor markers has limitations. However, core needle biopsy has the risk of misdiagnosis and tumor cell dissemination, therefore surgical resection should be considered when comprehensive findings indicate a potential recurrence.
期刊介绍:
Thoracic Cancer aims to facilitate international collaboration and exchange of comprehensive and cutting-edge information on basic, translational, and applied clinical research in lung cancer, esophageal cancer, mediastinal cancer, breast cancer and other thoracic malignancies. Prevention, treatment and research relevant to Asia-Pacific is a focus area, but submissions from all regions are welcomed. The editors encourage contributions relevant to prevention, general thoracic surgery, medical oncology, radiology, radiation medicine, pathology, basic cancer research, as well as epidemiological and translational studies in thoracic cancer. Thoracic Cancer is the official publication of the Chinese Society of Lung Cancer, International Chinese Society of Thoracic Surgery and is endorsed by the Korean Association for the Study of Lung Cancer and the Hong Kong Cancer Therapy Society.
The Journal publishes a range of article types including: Editorials, Invited Reviews, Mini Reviews, Original Articles, Clinical Guidelines, Technological Notes, Imaging in thoracic cancer, Meeting Reports, Case Reports, Letters to the Editor, Commentaries, and Brief Reports.
