Abstract
Purpose: Haemangiomas and vascular malformations are not easy to differentiate clinically. We describe a patient who was initially thought to have a scrotal venous malformation (VM) but after pathological examination was diagnosed to be afflicted with an arteriovenous malformation (AVM) with a micro-fistula in pathorogical photo. We think that even if there are suspicions of VM before the operation, the importance of resection with an ample margin of safety is indicated. Material and Method: A 38-year-old man who noticed a mass in his scrotum. The patient was seen at our hospital in May 2009 with concern for progression of the scrotal mass. That mass appeared to indicate a simple case of VM of the scrotum. Result and Conclusion: A biopsy of the mass was performed and was diagnosed to be a micro-fistula AVM, with no tumour growth in the vascular endothelial cells. Resection was performed in September 2009. And there is no recurrence. Even if there are suspicions of VM before the operation, the importance of resection with an ample margin of safety is indicated.
Highlights
There are two types in vascular anomalies, one shows endothelial hyperplasia designated as hemangiomas, and the other, which does not show endothelial hyperplasia, is called malformation
We report a patient who was initially believed to have a scrotally-positioned venous malformation (VM) before the operation and later diagnosed as an arteriovenous malformation (AVM) upon biopsy and pathological analysis
The patient, was not able to provide the diagnosis of the VM AVM arteriovenous fistula (AVF)
Summary
There are two types in vascular anomalies, one shows endothelial hyperplasia designated as hemangiomas, and the other, which does not show endothelial hyperplasia, is called malformation. We report a patient who was initially believed to have a scrotally-positioned venous malformation (VM) before the operation and later diagnosed as an arteriovenous malformation (AVM) upon biopsy and pathological analysis. A complete resection was performed of the lesion. Haemangiomas and vascular malformations are not easy to differentiate clinically and even if there are suspicions of VM before the operation, the importance of resection with an ample margin of safety is indicated (Table 1)
