Core Tip

Core tip: A retroperitoneal cavernous hemangioma is a rare disease. This case of retroperitoneal hemangioma had uniquely invaded into the duodenum and pancreas head, and thus required treatment with pylorus preserving pancreaticoduodenectomy. Although hemangiomas are typically benign, clinicians should be aware of the possibility of invasion into the surrounding organs such as with this case. In the event of invasion, we recommend a combined resection of both the tumor and affected organs to reduce the chance of local recurrence that may be associated with inadequate resection.
