Misdiagnosed Scrotal Arteriovenous Malformation and the Role of Clinical Assessment: A Case Report.

Vascular anomalies usually present at the beginning of life and vary in their course of progression and treatment. The pinpoint diagnosis of each lesion is often misdirected, owing to the complexity surrounding the classification. At the broadest level, differentiation between tumoral structures such as hemangiomas and other vascular malformations is required to not only select the correct procedure, but more importantly determining whether treatment is necessary. A 3-year-old patient presented to our institution with a vascular lesion in the scrotum, which had been labeled as a hemangioma. The unusual prognosis and continuous growth of the lesion suggested otherwise. Comprehensive clinical assessment was conducted, and the physical examination allowed for the accurate diagnosis of an arteriovenous malformation. The lesion was successfully excised without harm to the underlying structures. The authors uphold that misdiagnosis across vascular lesions is preventable through the correct clinical approach.
