Acral Arteriovenous Hemangioma: A Case Report and the Utility of Ultra-High Frequency Ultrasound (UHFUS) in Diagnosis

Acral arteriovenous hemangioma is a rare vascular lesion with an uncertain etiology predominantly affecting middle- aged adults. The lesion typically manifests as a painless 0.5-1 cm erythematous-violaceous papule, predominantly affecting the face and extremities [1]. We present a case study of a middle-aged female diagnosed with acral arteriovenous hemangioma of the lower lip. The clinical, histological, dermoscopic, and immunohistochemical features of this condition are discussed, highlighting the importance of a multidimensional diagnostic approach. Additionally, the application of ultra-high frequency ultrasound (UHFUS) with color Doppler as a diagnostic tool is introduced. © 2024 Guida et al.
