Resection of a capillary haemangioma using robotic‐assisted thoracic surgery: A case report

Abstract

Abstract Capillary haemangioma is a rare condition that is difficult to diagnose preoperatively because of its rarity and nonspecific imaging findings. In this report, we describe a case of capillary haemangioma diagnosed by robot‐assisted thoracic surgery (RATS). A 72‐year‐old man was incidentally found to have an anterior mediastinal tumour on chest computed tomography. The preoperative imaging findings were indicative of thymoma, and surgical treatment by RATS was selected. The intraoperative findings suggested that the tumour was a haemangioma originating from the pericardiophrenic vein. The pathological findings revealed a well‐defined tumour with capillaries in a vascular‐like structure and some thrombus formation. The pathological diagnosis was capillary haemangioma. The patient was discharged unaided at 7 days postoperatively and no recurrence was observed at 16 months postoperatively.
